European Photovoltaic technology development vision and strategic planning

Currently the European solar generator photovoltaic technology has begun to commercialize and has been widely used in Europe to improve its energy security, increase employment opportunities and improve the living conditions of citizens in remote areas to improve the welfare of civil society has played an increasingly important effect. With solar photovoltaic power generation system products are widely used in Europe, it is in improving Europe's energy supply security plays an increasingly important role and because it has a particularly suited to provide energy to remote areas of the characteristics, it is possible to improve education in these areas and the level of health care, providing more opportunities for economic development and to ease the flow of people in remote areas to big cities. In 2005 the European solar photovoltaic industry for the European citizens about 2500 jobs (per MWp production capacity will create 20 jobs per MWp installed capacity of the installation to create 30 jobs), although with the price of solar power systems decline in labor demand will decline, but with the rapid development of its market, will still provide more employment opportunities for Europe.

Europe the current price level of the solar photovoltaic power generation system enables solar power to meet the electricity demand during peak periods, and can alternate with other independent power systems: competition (such as diesel power generation system), but its price has not been reduced to the electricity consumers acceptable level.

Strategic Objectives: at European level the EU has developed to achieve by 2010 3GWp of the total installed capacity of portable solar generator development goals "of the European Community Strategy and Action Plan" white paper. In addition, the European Photovoltaic Technology Platform proposed in the early days in order to accelerate the development of sustainable energy power solar photovoltaic industry in Europe, and in 2030 making European solar photovoltaic power generation target of 4% of global reach. After the European Photovoltaic Technology Platform was established soon, solar photovoltaic technology Research Advisory Committee (PV-TRAC) released a report titled "Photovoltaic Technology Foresight", the report proposes a realistic and ambitious development goals: to make the EU's solar photovoltaic power system installed capacity in 2030 reached 200GWp (then the world's solar photovoltaic systems installed about 1000 GWp).

European technology platform in July 2007 released a strategic research agenda, the European Photovoltaic Technology Platform detailed description of its overall short-term research and development goals: By 2015, in southern Europe solar off grid solar system reaches the consumer price acceptable level, this goal can be quantified in the cost of solar photovoltaic power generation system for 0.15 euros / kwh, or the entire solar photovoltaic system price of 2.5 euros / Wp.

About off grid solar system

The principle of solar generator photovoltaic system Diagram in the daytime, under the light conditions, solar modules produce a certain amount of force is formed by series-parallel solar cell matrix components, making the square voltage reaches the system input voltage requirements. Through the charge controller to charge the battery, it will be converted from light energy stored up energy.

 

Evening batteries provide input power to the inverter, by the action of the inverter, the direct current into alternating current supplied to the power distribution cabinet, distribution cabinet by the switching action of the power supply. Discharge of the battery pack case is controlled by the controller to ensure that the normal use of the battery. PV power plant system also limited load protection and lightning protection devices to protect the system equipment from lightning and over-load operation, maintenance, use of safety system equipment. Solar energy  → electrical energy → light energy → chemical energy.

 

Part of the photovoltaic system is composed of square solar cells of off grid solar system, battery, charge controller, inverter, AC power distribution counters, automatic solar tracking system, automatic dust removal system, solar modules and other equipment. Its role is to various pieces of equipment: solar cell matrix in the presence of light (either sunlight or other light emitters generate light), the cells absorb light energy, different signs appear accumulated charge across the battery terminals, which produce photovoltage which is the" photovoltaic effect. " In the photovoltaic effect the role of force is generated at both ends of the solar cell, light energy is converted into electrical energy, energy conversion devices. Silicon solar cell is generally divided into single crystal silicon solar cells, polycrystalline silicon solar cells and amorphous silicon solar cell three. Its role is to store the battery pack power when the solar cell matrix issued by the light and are ready to supply the load.

The basic requirement for solar backup power are used:

a. Self-discharge rate

b. Long life

c. Strong deep discharge capability

d. High charging efficiency

e. Low-maintenance or maintenance-free

f. Wide operating temperature range

g. Low prices.

Our current batteries and solar power generation systems supporting the use of lead-acid batteries and are mainly nickel-cadmium batteries. Supporting more than 200Ah lead-acid batteries, generally used fixed or sealed lead-acid industrial batteries, each battery is rated at 2VDC; supporting the following 200Ah lead-acid batteries, generally used in small sealed maintenance-free lead-acid batteries, each only the rated battery voltage is 12VDC. Charge controller is able to automatically prevent battery overcharge and over-discharge device. Because of the battery charge and discharge cycles and the depth is an important factor in the decision to discharge the battery life, so they can control the battery overcharge or over-discharge charge controller is essential equipment. The inverter is a direct current into alternating current equipment. Since solar cells and batteries is a DC power supply and the load when the AC load, an inverter is necessary. The inverter according to operating mode can be divided into stand-alone inverters and grid inverter. Stand-alone inverters for solar power generation systems operate independently, as a separate load. Grid inverter for solar backup generator and network operation. The inverter output waveform can be divided by the square wave inverter and sine wave inverter. Square wave inverter circuit is simple, low cost, but large harmonic components, generally used for several hundred watts and less demanding on the harmonic system. Sine wave inverter high cost, but it can be applied to a variety of loads.

Inverter protection function:

a, Overload protection

b, Short circuit protection

c, Reverse protection

d, Undervoltage protection

e, Overvoltage protection

f, overheating protection

AC power distribution cabinet which is on standby inverter switching a major role in solar power kit off , to ensure the normal power supply system, as well as measurement of electrical energy on the line.

Road solar power be reality

With the continuous development of science and technology to enhance scientific and technological content of solar energy storage, Road power has become a reality. the Netherlands Organization for Applied Scientific Research (TNO) consortium 25 kilometers from Amsterdam's city Keluomoni laying of a 70 m-long solar cycle paths, the total cost of the project, it’s scheduled Nov. 12, open to the public.

In fact the plan in early 2011 began planning the development, originally it planned to be completed by 2012, but for various reasons in recent days was formally commenced laying. This solar bicycle path by the solar panels covering the surface of a block of concrete cement blocks mosaic, covering the surface of crystalline solar cell panel is only 1 inch (about 2.5cm) thick, was able to withstand the weight of a truck. Although solar panels can’t move for maximum sunlight range, but Article 70 m long driveway three families to provide adequate electricity.

Vision Netherlands TNO is extensive paved driveway solar generator, It is producing enough electricity supply electric vehicles, road lighting and household electricity companies, and ultimately reduce the ultimate goal of the world's dependence on fossil fuels, renewable energy to create a system of supply and demand. But the biggest obstacle currently facing the plan is expensive cost.

So far the production cost of the project is about 1.5 million euros, complete the laying of the construction project will cost a total of up to 3 million euros. Although costly, but the prospect of TNO in the Netherlands this project is still very optimistic, they said when the solar panels become cheaper, the cost of production of the off grid solar system project will be greatly reduced. TNO in the Netherlands plans to expand the 2016 bike lanes to 100 meters and may indicate that the item to other regions.

Seven-step solar portable solar generator for homes

Now when the increasing awareness of environmental protection and as well as full support for families of small- portable solar generator construction projects in the country. Household solar power plant is also one of the most flexible and the most popular family. Solar power as long as the place where the sunlight can build their own small home solar power stations. However, after the family built a small power stations, and to achieve the net, we need to take the seven steps of the electricity sector.

Home solar power station and network seven-step:

1、  Electric Power Bureau to apply for the operating room, fill out the application and the network form. (It is necessary with identity cards and a copy of the head of household, real estate license and other related documents when families apply.)

2、Home electricity sector survey and issue personalized and programs of off grid solar system in 10 working days.

3、Family and confirm net programs

4、According to the network solutions, the family design photovoltaic power stations detailed.

5、In accordance with the relevant technical requirements to purchase equipment, the average family 5 kilowatts 6 kilowatts of capacity has been sufficient. Contact a professional for installation.

6、Family raised grid network debugging application, power companies install metering meter, organizational acceptance, and signed relevant agreements

7、After testing, the grid network has officially completed.

Of course solar generator power stations and network application is free. Completed the individual and the state power grid, the solar generator can be their own excess electricity sold to the state and get some appropriate subsidies. Meanwhile make their own cost to recover faster.

In addition for 380 volts and below the solar grid project, the electricity sector commitment in 35 working days to complete the grid and network flow;10 KV level and network project commitments in 45 working days to complete the grid and network processes.

Who Restricting the market of Chinese PV application? 3-3

Policy measures to support PV unsound

The high cost of solar generator and grid has been a difficult two problems hinder the development of the domestic PV market. So while the Government through the development of price subsidies to get rid of the high price of photovoltaic power generation "bottleneck" to shorten the payback period investors; on the other hand to support through the introduction of photovoltaic power generation and network and network policies. Development and implementation of national policy determines the size of the PV market. At present, China's PV support policies are not perfect, there are some problems in the operation mechanism.

Supporting policies is not perfect one reflected on the support of distributed applications in photovoltaic electricity subsidies based on the current investment subsidies have not yet introduced, the lack of household, commercial and industrial companies to install photovoltaic systems initial investment subsidy, soft loan deals or tax breaks, and other related policies.

Due to the high initial investment of photovoltaic solar energy storage, based on China's current per capita income levels, only to reduce the initial investment in order to mobilize their personal passion for installation, while China's current policy does not address the photovoltaic. Supporting policies is not perfect and is also reflected in the absence of the introduction of network policies for large-scale photovoltaic power plants and large-scale photovoltaic power plants net flow is still cumbersome and lengthy.

State Grid Corporation in October 2012 26 issued a "do a good job of distributed photovoltaic power generation and network service Work", the process is simplified and the network 6 megawatts of distributed PV power plant, theoretically solve the distributed photovoltaic grid problems. And subsidies, as this policy is also only "opinions", the lack of laws and regulations to protect their execution.

Look subsidies, how to ensure that one country subsidy funding. PV subsidies, mainly from renewable energy tariff surcharge, state funding accounted for a smaller proportion. 15 July 2013, the State Council issued the "Opinions on promoting the healthy development of off grid solar system," he pointed out that by 2015 China's total installed capacity of PV to reach 35 million kilowatts (35GW) above. By the end of 2013, China's cumulative installed PV about 18.1GW, generating 110 billion a year to 120 billion degrees, according to subsidize 0.42 yuan / kWh basis, the corresponding need more than 400 billion yuan of subsidies. If the completion of the annual installed capacity of 35GW generation can reach 2000-2500 million degrees, the annual subsidy needed to 840w ~ 1050 yuan.

1.5 cents per kilowatt of renewable energy tariff additional criteria from 25 September 2013 in accordance with the beginning of the implementation of the (previously 0.8) and 2013 to calculate the whole society electricity consumption 5.3223 trillion kwh, electricity additional income was only 800 billion. It should be noted that the tariff surcharge levied not only established as PV, is renewable energy, count wind, biomass, etc., really very little money left for the photovoltaic industry. And additional tariff only except residents and other agricultural production of electricity levy. Current photovoltaic subsidies have a gap, 2015, the funding gap will be even greater.

The second is how to ensure that government subsidies fair, in full, on time and persistence paid. Subsidy arrears in the country has built large-scale ground photovoltaic power plants are prevalent, it can be said to have been the origin of a long time. Large-scale ground photovoltaic power station construction and operation need to take a lot of money, subsidies are not in place, the power plant to sell electricity grid can only get 0.4 to 0.5 yuan desulfurization sales price, the proceeds to repay even the interest on the loan operation and maintenance of power plants are often mouth not enough. Investors not only through the construction of photovoltaic power plants can’t be profitable, but also a loss is likely to occur. This situation will undoubtedly affect the enthusiasm of the other investors in the construction of solar backup generator plants.

In addition, the implementation of the results and net policies and subsidies can also be seen reflected in the 2013 case of distributed PV installed capacity in 2013, China's installed capacity of distributed PV 3GW, most of which come from 2012, had been approved the "Golden sun" demonstration project, based on real electricity subsidy model projects a few hundred megawatts, and none of these big projects and networks.

Technical standards and certification system is not perfect

Photovoltaic power generation projects with huge investment, the project is completed long running time, harsh operating environment, and the project operation and production and life are closely related features. Therefore, to ensure that quality is the key photovoltaic power projects, and is a prerequisite for photovoltaic applications PV industry development. Ensure quality PV products and photovoltaic power plant safe and stable operation of the need to improve product standards and strict certification system. The lack of standards and certification of photovoltaic products easily lead to uneven quality, unstable system operation, and low power generation efficiency, thereby affecting the reputation of the industry, the public investment in the fight against the construction of photovoltaic power generation project enthusiasm, and ultimately impede the orderly development of the PV market.

All along, China's photovoltaic industry chain are facing the problem of lack of standards, from the PV original, specification and auxiliary materials to the photovoltaic cell, product performance testing components, and power station construction application terminal, etc., are in part or all of the missing state standards . Meanwhile, China's current portable solar generator standards already lack the practical implementation of mandatory authority, many of the standard has not been implemented. In addition, subject to the limits of the annual publication of the number of national standards published by the speed it is difficult to meet the market demand for rapid development of the industry in some areas led to the existence of standards do not apply or do not scale to follow the case, the urgent need to strengthen the standards system revision.

Compulsory certification is international practice, strict certification system can provide photovoltaic applications escort, but China has not yet officially launched the field of photovoltaic-related certification, already insufficient to carry out certification authority. Resulting in many domestic enterprises need to get the foreign certification of photovoltaic products, increased product costs. The lack of accreditation of photovoltaic products difficult to obtain market acceptance, sales limited.

At present, China PV application market development is still in its infancy, the future with the expansion of market size, lack of standards and certification restraining effect on market development will become more apparent.

Lack of photovoltaic professionals

Although China has opened several universities Photovoltaic, relevant research institutions are also the training of professionals PV, but because of the photovoltaic industry is the emerging technology-intensive industries, the development time is short, fast growth, the lack of industry and related in-depth understanding of discipline, training programs, etc. imperfect conditions and teachers, resulting in the quantity and quality of talent photovoltaic research and development, design, production, construction and other aspects difficult to meet the needs of China's photovoltaic enterprises. Lack of talent makes a considerable number of photovoltaic solar electric generator enterprises lack independent innovation capability and autonomous technology, the overall R & D and mass production technology and international advanced level there is a certain gap. Some enterprises can only dig everywhere, additional human resources costs.

On the other hand, the lack of appropriate vocational schools, technical schools and vocational skills training related to photovoltaic power generation, the current number of employees and professional quality photovoltaic power generation is difficult to guarantee. And for the ordinary people of publicity, education, training popularize basic knowledge of photovoltaic power generation has not yet carried out.

Who Restricting the market of Chinese PV application? 2-3

Since the photovoltaic of solar power generator system by weather big impact. The absence of large energy storage devices, encountered continuous rainy weather if the photovoltaic system generating capacity can’t meet the continuous industrial and commercial users of electricity demand, the user may face today with a photovoltaic power grid for tomorrow's embarrassment, will cause the user the reverse psychology is investors need to consider.

Low price of residential electricity, off grid solar system in the civilian market unattractive. If the national electricity subsidies, based on the local government and then give a certain amount of electricity or government subsidies to install photovoltaic systems users give a certain percentage of the initial investment subsidy, so that the civilian PV system becomes as profitable. Based on our country's specific national conditions, it is also facing a lot of problems.

In the city the majority of people living in a dozen layers, 20 layers of the building's residents, most of the roof space drainage air conditioning systems, solar generator hot water systems and other ancillary facilities to occupy the property, can really be used to PV very limited. Investors need to spend a lot of manpower and resources to find the idle roof, potentially increasing construction costs. Even found a suitable roof, because it belongs to the public area, you want to install photovoltaic systems on the roof requires unanimous consent of all the owners. The national grid solar system in a distributed power plant projects receiving the application, the applicant must also required to provide identity cards, real estate license and other materials; occupy public areas to provide proof of the consent of other owners, property, neighborhood. So, we want in China's urban residents roof construction of photovoltaic power plants, regardless of the owner or a third party builder, his public relations capacity requirements are very high.

In our countryside, although abundant resources and household roof house roof farmers call the shots, but the problem may be facing more. Less electricity and off grid solar system infrastructure is poor, the farmers can’t afford the high initial investment. Resulting in less power installed capacity is limited; resulting in poor grid infrastructure requires additional substantial investment; farmers can’t afford, and if the introduction of outside investors, the roof was dispersed in every household, administrative costs will be high.

Indeed the investors and investment experience will encounter obstacles far more than those listed above, there are many obstacles that investors can’t control or can’t be expected, national policies are also difficult to solve.

The issue of Technical and institutional of photovoltaic grid solar system

Now China has built large-scale ground photovoltaic power plants and generally facing difficult network problems. One reason is that large-scale ground photovoltaic power plants mainly in the construction of the western desert region in China. These areas far from load centers, economic underdevelopment, low industrial and population, not much electricity, hydropower, wind power already can’t consumptive. So often it requires long-distance transmission to the photovoltaic transported to the load centers. However, due to the local grid infrastructure is extremely inadequate, and to network, many photovoltaic solar energy storage plant builders have additional investment to spend money to purchase and installation of network equipment, and even the construction of transmission lines and substations, and net amount of money reduce the cost of power station construction economy.

Grid PV power plant has been due to receive restricted grid capacity and other factors, resulting in brownouts have occurred, plus subsidies paid in time, have built a lot of PV power plant is idle; there is a reason that the rv solar power company cumbersome and network processes, photovoltaic power plant builders to spend at least six months to a year, photovoltaic power plants to the grid. And around the grid company will continue to transform the requirements, but also to the cost of photovoltaic power plant in an unexpected layers accumulated. Since the grid company can determine whether a photovoltaic power station and the network, so no matter whether the reasonable requirements of the power grid company, photovoltaic power plants must meet.

PV is mainly distributed in the eastern part of the development of grid infrastructure is much better compared to the western region, builders do not need to invest in the power facilities, the State solar off grid kit Corporation also introduced support for distributed PV grid policy, but difficult grid the problem still remains. Residents in the submission of an application to access the distributed photovoltaic project country network operating room, met a variety of issues, such as the need for natural persons approved projects, the construction unit of qualification requirements, leading to the application and the network is not through combat the enthusiasm of the residents.

Grid Company "difficult" PV Grid reason lies first and foremost technical problems. Since PV affected season, weather, environment and circadian turnover, continuity and stability of poor shortcomings, coupled with China's power grid and other infrastructure behind, and large-scale photovoltaic power generation grid network will interfere with the normal scheduling on the grid safe and stable operation of the threat.

Compared with the technical issues, the more important reason is that the portable solar power system damaged the interests of the company. Grid standing business point of view, it did not receive any benefit PV: First, self-occupied photovoltaic electricity will directly lead to reduction in income once the electricity grid. Second, in order to acquire photovoltaic grid company also invested a lot of infrastructure, spend huge amounts of money. Third, China's coal industry overcapacity, thermal power generation rich. And since entering 2013, coal prices decline, dramatically reducing the cost of thermal power generation. In addition to the energy saving this reason, the power grid really do not want cheap coal-fired power lay not, try and accept the high cost of network problems the addition of PV.

Currently, the power grid enterprises distributed PV "friendly" attitude mainly forced national political pressure, but also because a small number of distributed power generation capacity, not amount to anything, grid companies temporarily support the fundamental interests will not pose a threat to it. If the interests of the future large-scale application of distributed photovoltaic power grid enterprises are still not taking into account, I believe that they treat distributed PV change attitudes will occur immediately.

National Grid does not support photovoltaic grid deeper reason is that China's electric solar portable generator. In China, the monopoly power grid transmission from the sale of electricity to end all aspects, both grid electricity buyers to purchase unique power plant, it is the only vendor to sell users of electricity. This vertically integrated monopoly, fundamentally hinder the development of photovoltaic and other new energy power.

The difference of inverter between off grid solar system and grid solar system

The difference of inverter between off grid solar system and grid solar system isn’t very big. If we know about it, it is very good for choose the product of solar generator and considered after the safe operation of the grid and the grid.

The inverter of Off grid solar system input voltage is fixed, 12/24/48/110 / 220V, it needs to keep the battery charged and then reverse into alternating current; but the inverter of grid solar system has a wide voltage range input voltage 100V- 1000V, directly connected with the solar panels together; understanding of solar inverters of off grid solar power kits and grid-connected inverters difference, take a look at their features:

Features of PV off grid solar system inverter 

After the inverter of solar off grid kit leaving the grid can work independently, the equivalent of a small independent power grids, mainly to control their voltage is a voltage source. Available with resistive-capacitive and inductive motors and other loads, fast response interference, adaptability and practical, the power supply and emergency power supply of choice for outdoor power products.

The inverter of PV solar kit off grid is suitable for electric power systems, communication systems, railroad systems, shipping, hospitals, shopping malls, schools, outdoor and other places, access to electricity can trickle charge the battery, you can set the priority rife photovoltaic electricity reserve, or electricity priority scenery solar backup power.

Features of PV grid solar system inverter 

                       

The inverter of PV grid solar system need to be connected with the electricity grid, it doesn’t work off the grid, it is necessary to detect the output of the local power grid network and bring the case before the action. To power transmission grid due to be consistent when and net output in phase, frequency, voltage and power grids.

The inverter of PV grid solar system does not need storage, but the energy can’t control, how much electricity photovoltaic power line transmission go out how much electricity, like a small power plant.

How the new lithium solar energy storage technology to enhance the efficiency of the PV system

University of Southampton and REA Psystems collaborative research discovered a new type of lithium battery as the solar energy storage device PV systems, solar energy storage efficiency can be increased to 95%, can greatly reduce the cost of solar power.

Most current PV system also uses lead-acid batteries as the solar backup generator device, there is far, lithium iron phosphate battery replacement can give full play to its advantages, including improved storage efficiency, long life, low unit cost, and so on. The type lithium is used as an solar energy storage device, the energy efficiency can be increased to 95%, far more than 80% of the traditional lead-acid batteries, and has 1,600 charge-discharge life.

Lead-acid battery of solar generator energy storage device is used in most traditional photovoltaic systems. However, as the energy storage device, lithium batteries, especially the LiFePO4 batteries we use, have more favorable characteristics.

Collect these data, it is necessary to connect the lithium iron phosphate battery and off grid Solar System，PV systems installed in the building at the University of use provided by the REA Psystems specially designed battery management system. someone added, "Research shows that 95% of the lithium battery energy efficiency, and the most commonly used lead-acid batteries, only about 80 percent, while the lithium battery lighter and has a longer use than lead-acid batteries life. charge and discharge times can reach 1600 cycles, which means they do not need regular replacement.” 

Although before commercial photovoltaic systems, batteries need further testing. But studies have shown that, LiFePO4 battery is expected to improve the efficiency of solar power kit off grid generation system, and helps reduce installation and maintenance costs.

For a variety of energy sources (renewable or non-renewable), solar energy storage devices, such as batteries, plays an important role in terms of energy solar backup generator use, with the traditional lead compared acid batteries, LiFePO4 battery has a higher efficiency, longer life, lighter weight, cost less. we expect to be able to see such batteries are widely used in photovoltaic systems and other renewable energy off grid solar systems.

The difference between grid and off grid solar generator system

The difference of Grid solar system and off grid solar power kits are different only the english word initially , now meant in the context of photovoltaics is an existing electricity grid. The two grid and off grid are essential for the photovoltaic.

A.      Grid solar System in photovoltaics

In a grid solar system is a photovoltaic system that produces electricity, this solar energy storage is then fed into an existing to public network. The solar backup power generator is NEBEM (the interconnected modules) an inverter necessary because in public power grids alternating current flows. In the grid solar systems, a distinction is in photovoltaics between different concepts:

1.       Grid Solar systems in which the photovoltaic system is used to supply a load parallel to the public grid. The decentralized solar energy storage is produced close to the consumer, so large transport losses can be excluded.

2.       Grid solar systems in which the photovoltaic system supplies the consumer an alternative to the public network. Here, the consumer is indeed also connected to the public network, the solar power backup generator is decentralized, so the draw-off produced. But instead feed surpluses into the public grid, these are primarily stored in the energy storage. This Grid Solar System provides mainly for a higher security of supply and is often used in weaker supply networks, as so-called backup system.

3.       Grid Solar systems supply consumers in parallel with the public network,the known grid solar  systems, such as are used in Germany and other industrialized countries. Grid systems that exert a so-called backup function are rather used in emerging markets or developing countries.

B.      Off Grid solar System in photovoltaics

In an off grid solar system is a stand-alone system. Such a photovoltaic system is therefore not connected to a public electricity grid and only works with energy storage. Such off grid solar systems or stand-alone systems have greater market share in the early days of Phovoltaik. Today they are primarily in cottages used, which are not connected to a public network because of the distance. Off grid solar power kits photovoltaic systems are also used in boats or caravans. Another application for Off Grid solar system photovoltaic is for example in the operation of desalination plants or water pumps. the market share is growing, especially in developing countries. 

How to use off grid solar system products and get return on investment

Now by the financial market downturn, the stock market is always ups and downs, the real chance to earn from small, most investors only cast money into and be rewarded. If there is a product off grid solar system not only meet our daily needs and can easily earn high fees, over three to five years to be profitable during this period can’t be charged extra electricity costs.

Now all over the world to respond to the needs of environmental protection, encourage the use of solar generator energy storage products, which introduced a series of measures of financial subsidies generally high capacity PV off grid solar system energy storage power station not only for their own use can also be the transmission to the public grid. The each country can subsidize these additional power.

The following I will be in Germany, for example, a table clearly shows that ROI so that we can according to the size of their own area to install solar panels to convert solar compute power, the wider region to install more solar panels, and produce conversion of more power. that we can choose the higher capacity of photovoltaic solar energy storage products. the faster the greater the capacity of our returns generated.

Compared to the uncertainty of the stock, it is not that PV portable solar generator production capacity product is a good choice? Either support our cause, to meet our demand for electricity, and can be recovered in a short time we invested in solar energy storage products before buying costs. why not? As long as we together reduce the demand for traditional non-renewable energy, environmental protection of our road will go farther and farther, farther good. can according to the size of their own area to install solar panels to convert solar compute power, the wider region to install more solar panels, and produce conversion of more power. that we can choose the higher capacity of photovoltaic solar energy storage products. the faster the greater the capacity of our returns generated.

The attention of safety knowledge for installation of photovoltaic solar generator

"Safety " is the basic principle firstly. In order to successfully complete the photovoltaic solar generator installation tasks, you must something as the following.

1. Equipment manufacturers comply with the provisions of installation specifications and the necessary application codes and standards.

2. Prepared completamente

Full preparatory work for construction in remote areas is particularly important, we must ensure that all the materials needed to build power plants, equipment, tools, installation drawings and information brought to the scene. Site for a variety of emergency situations that may arise must have the appropriate preparations. Site construction leaders and key personnel should be familiar with the venue, transportation, topography, climate, and human environment, should know how to injured people evacuated as soon as possible. Be sure to prepare a communication tool with the outside world. Bring enough clothes, food and temporary accommodation appliance, which in the wild is very necessary temporary overnight.

3. Reasonable arrangements and strengthen coordination

The installation site of solar generator must be given ample time to work aside to ask, which is particularly important in inaccessible remote areas. Only in this way can calmly work site staff, to avoid in order to finish the work, the phenomenon appears hectic at work and accidents.

Construction project can not be completed on time may cause a lot of problems, such as increased costs. Inconvenience to local users, but also to the installers trouble. To install work smoothly requires a reasonable time, at the same time pay attention to the coordination of the progress of work solar backup generator . Whenever the next step before installation, all the necessary preparatory work must be done according to the requirements.

4. Prepare construction drawings and technical documents

Site preparation and placement of equipment must be accountable to all construction workers clear the site of all buildings, foundations, cable trenches, pipes, cable laying paths and walls and so must be accurately marked on construction plans and technical detailed log file.

5. Enhanced environmental awareness, the use of new materials and new technology

Stand-alone PV power plant built in remote areas generally untapped, near agricultural areas or water. Unreasonable installation may result in water pollution and damage to crops, livestock and even affect wildlife survival. The installer of off grid solar system should have the basic knowledge and understanding of environmental protection of certain hazardous substances. Note the use of new materials and new technology emerging as an alternative to harmful traditional materials and old craft.

All the people must remember that, in the power engineering construction, there is always the potential danger and insecurity, time can’t be taken lightly. Throughout the installation of photovoltaic solar energy storage and the installation is completed to ask the inspection process, we must carefully check each part of the system to ensure the safe operation of power plants and the safety of nearby residents or pedestrians construction workers.

Stand-alone photovoltaic systems are often located in remote areas, so the design and installation work will encounter difficulties such as transport, installation materials and other aspects. When designers or installers in planning the installation of photovoltaic systems in remote, should be planned and ready to install the tools and materials needed. It may not have specialized electrical shop near the remote installation site, so well-planned pre-construction is necessary. Due to the specific circumstances of each construction site is different, the installer should first examine the site before construction, detailed study should be required to list the tools and materials of off grid solar system.

The applicability of new energy product portable solar generator

The technology of solar energy storage systems as the key to new energy development and the new energy era, it will change the energy landscape of the whole world. As long as solar energy storage system technology is more economical, it will open a gateway to a new era of global energy. Effective integration of electric vehicles, energy storage technologies and wind power, solar energy, can form an effective substitute for petroleum, energy security, and therefore the development of solar energy storage technology is more and more important and urgent, so its importance is self-evident.

With the continuous development of portable solar generator energy storage system technology, diversification and cost reduction, in line with the more different needs of families so as to be accepted by all, such off grid solar system is completely independent of the public grid system, Any place is very suitable for non-grid areas or travel, light and easy to carry portable solar power system. the networking system can be connected to the public grid system in order to achieve complementarity electricity, and even delivered to the grid system. system capacity to be based on each family or individual's own electricity consumption demand, personalized design.

Portable solar generator storage systems or solar off grid  kit system installation is very easy, you only need to connect solar panels can charge while and net system by simply connecting the public grid for charging. Convenient and flexible, simple to apply in line with the requirements of each consumer.

How to choose a solar generator kit for home accurately

When customers choosing a solar generator system, first of all according to their own needs that for pure lighting or household electric appliances, in addition installed off-grid or grid. If you are living without electricity shortage areas, you can only choose off-grid power systems and 1000 watts of small portable solar generator; en the area with electricity easily grid system and optional 2000W or more, so as to achieve the purpose of saving electricity costs.

1.The use of pure lighting or using appliances

Solar generator system is divided into two types according to their functions, family of DC lighting system one simple lighting; the second is that is can lighting and can be used for household appliances have 220V / 110V AC output power generation system. Lighting system features a simple and cost-effective, but not for household electric appliances.

2. Which is better the portable solar generator or modular

The portable machine is a portable and free installation features, ideal for outdoor camping, but due to the limited volume, storage capacity is too small, the high cost. Need a simple modular installation, large capacity storage, both practical and affordable more suitable for home users and home use outdoors.

3.Off grid solar system or grid

Current types of solar power generation systems have off-grid and grid, grid energy storage and two types of non-storage devices. Each of the components has the difference and suitable for use not the same place. Cost varies widely, higher cost of off-grid systems and network systems, energy storage devices and network storage devices and those without network system. Off-grid solar power system is suitable for use anywhere, but is only suitable for the grid can be incorporated into the public grid places.

4.About the size of system capacity

System capacity is the size of the solar power system size or the number of solar panels installed, and whether it is in the net or off grid solar power kits power systems for power generation systems from net buyers need to pay attention to distinguish the size of the panel or inverter the size of the output, the inverter output capacity is not associated with the system.

Solar power system is not a standardized product and suitable for all users, to be based on the user's situation to design and configuration, in different places, using the type will be different. To have the intention to install solar power systems in order after the customer must understand clearly the right choice for solar power systems.
