The solar industry is still a market trend today

From the current situation the shipments and quotations of photovoltaic solar generator product are higher, it is beginning to recover the vocational, but not out of the woods to say now. Trina Solar Chairman CEO thought, the career internal shuffling process is not over really want to revive it, it will take two to three years from the inside, it also needs to be a better combination of annexation , career planning inside the larger better company operations carried out the annexation of combining the advantages of skills, handling advantages and exploit the advantages of industry products, get very good competition advantage. However, numerous shopping malls optimistic about the latter part of the organization to carry out the photovoltaic solar industry.

"The overall judgment of 2013 - 2014 will still be in the economic recovery, 2014 the occupation format capable of exhibiting tight supply and demand situation, the continuous career earnings recovery trend." Organized thought, Details landing approach will promote the domestic launch of Distributed PV , along with estimated installed power plant construction will be presented to grab market from a long time to see a large burst will promote the use of domestic PV end mall, explore the distributed end business model will become the key of the solar energy storage to the future for some time.

Guoxin Securities believes that the fourth quarter is expected to all career advancement. "The current tariff policy introduced on the one hand to give the mall determination, it also plans to build a large power plant to supply conditions, on the whole profession to ensure normal work to bring. And despite the current end of the entire industrial manufacturing overcapacity still face difficulties, but because there is no sharp rise in commodity quotations and therefore this year the company presented decomposition, large companies gross margin and cash flow have shown significant improvement, while small and medium companies because cash flow cracking gradually withdraw mall, facing the annexation bound situation, all the supply and demand side tends to improve career. "

"Although the domestic price subsidies than-expected stocks can move back to the beginning part of the company's main shopping malls, but the experience of the owners two-year down cycle will be more careful on the resumption of production, so supply and demand side estimate will be further improved in the coming year, while domestic shopping malls If you need to render substantial installed capacity in the fourth quarter of this year, we will further improve the company's leading balance sheet and income statement, solar career upward trend and establish. "

China's PV industry to carry out prosperity in the face of Europe under the dual pressure, development of the domestic market, encouraging the use of distributed PV is correct. But relevant supporting guidelines must establish the correct understanding of the use of distributed photovoltaic solar off grid system skills to fit the economic laws, firmly grasp "the use of new energy sources in order to decrease the use of polluting emissions of power," the middle of the intention to make encouraging distributed PV fiscal spending effective role to play.

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.

For the largest solar-powered aircraft flight around the world

Now the advantage of solar technology not only reflected in the portable solar generator for home, its use is very extensive, such as the "Solar-driven" (Solar Impulse) is a Swiss-designed solar-powered aircraft, the prototype made of carbon fiber material with a seat, the wing has an elongated shape with a wingspan 63.4 m. and Airbus A340 aircraft considerably. The wing is covered with solar panels, total 11,628, which can be four total weight of 400kg battery charging. Due to the extensive use of lightweight carbon fiber composite materials, "Solar-driven" was weighing about 1600kg, equivalent to only the weight of a small truck. July 2010, the aircraft has created a manned solar aircraft 26 hours 10 minutes 19 seconds of flight time record, but also set an altitude of 9235 meters altitude record.

Today the "solar-driven" was also unveiled the second generation of the world. following the recent successful test flight, fly around the world are now ready to implement. "Solar-driven" 2 Payerne airbase in western Switzerland are tested for stability and driver training. Driving "the sun-driven"  5 days and nights global journey required two pilots, Borschberg has 25 years of experience in the Air Force is one of them. He said that in order to maintain focus and quick response in a long flight, he is trying to adapt twice a day for 20 minutes of sleep training.

According to plan, "Solar-driven" World Tour No. 2 departed from the Gulf, the Arabian Sea, has entered India, Burma, China, and then across the Pacific to the United States before flying to southern Europe and North Africa, and finally back to the starting point.

Borschberg said the project team early last year came into contact with the relevant Chinese authorities, permission to apply for flight, taking into account China's huge potential for green solar energy storage technology market, he looked forward to China will be "Solar-driven" Global Challenges 2 the indelible mark.

According to project founder, Swiss explorer Picard, the "Solar-driven" 2 covered by the more than 17,000 pieces of its wings thin solar panels convert solar energy into electrical energy, in addition to supply four engines, the excess energy can be stored in high energy density batteries, day and night non-stop flight.

April this year, the official debut of "Solar-driven" on the 2nd, is the world's largest solar-powered aircraft volume. Its wingspan of 72 meters, the size comparable to a Boeing 747-800 aircraft, but the weight is 2.3 tons.

"Solar-driven" when the 2nd actual flight, will first climb to 9,000 meters in height, gliding in slow decline is less dependent on electricity, while ensuring storage needs more power to deal with night flight. In theory, the sun never drive number can fly down, but the driver's physical but not guaranteed. "Solar-driven" 2 can be described as the current green energy-saving technology optimization portfolio to 16 aircraft bright landing lights, for example, only 100 watts of power consumption comparable home bedroom lighting, in addition to the energy loss of aircraft engines only 6%. The project team took core elements of solar panels and fuselage skeleton on display. If not personally seen, it is difficult to imagine the thickness of the plane solar panels equal to only hair thickness, good flexibility and flexibility; airframe made of carbon fiber, its strength level used in aviation, under the same conditions of paper weighs only one-third one.

Turning to prospects for solar-powered aircraft, Picard said that at present a large number of passengers transported on solar power generator isn’t feasible, but if the industry developed a better performance of solar cells and technology, the future of solar-powered aircraft may do more.

Solar power generation will be the window glass, curtains

Perhaps many people think that when the big city is not suitable for large solar energy storage station installation products, but also in top shape is not so fashionable in the city of skyscrapers, these gorgeous building that we are building more and more feel beautiful city. However, almost all the city buildings have a common that the appearance of glass-based. So with respect to such a vast place, we can be to play some role in it, in order to achieve conservation and utilization aspects of it?

MIT engineers recently developed a use of organic molecules can be used as windows panels of solar generator, Such panels can’t only take advantage of infrared energy from the sun also can make the natural light into the interior.

The new solar panels can be installed vertically in the window frame and has three major advantages: the accumulation of clean energy and convert it into electricity or heat chamber; of natural light into the room and because the material is completely transparent; installation cost ratio traditional low, as long as they will be installed in the original glass of the window frame to prepare.

Developed technology to produce a variety of beneficial to our lives everyday. Environmental protection in solar station today, such as solar car, solar flashlights, solar charging treasure, solar lamps, etc. We are very relevant and practical tools. Give us introduced a new solar products: solar curtains now.

We will be up every room curtains to prevent glare of the sun shining into. Nevertheless, the sun is isolated, but also wasted a lot of solar energy. If it’s able to take advantage of this time to block the sun, perhaps to save a lot of energy.

The solar curtain is such a design, it incorporates a soft curtain inside solar panels, so that will not affect the normal use of curtains, but also can absorb solar energy at the same time to draw the curtains and stored for future use. If you are around the house is covered by this curtain, then the day will be able to generate electricity about 16 degrees. It’s sufficient for a home using mostly.

But the current cost of curtain still relatively high and therefore can’t enter the market in the short term, but believe that with the continuous development of portable solar generator technology in the near future we can spend this energy saving products.

The new utilization of solar energy storage, environmental protection and convenience 2-2

Not only cars using solar energy off grid solar power kits as an energy source, and even aircraft can use solar energy for their life. Two swiss adventurer developed a new solar-powered aircraft, as long as there is solar radiation where it can continue to fly down. The plane uses the latest solar-powered aircraft Solar HB-SIA, which is a dedicated flat solar converter, very high conversion efficiency, allowing the aircraft to spend a minimum of energy in the air.

Using a variety of solar energy, "new ideas," so that people can enjoy the energy-saving and environmental protection in its convenience

Ford has launched a new solar car, solar car and previous biggest difference is that, this car roof solar cell has a special "condenser system" insufficient in the sun, but also to collect the sun light, fully charged within 1 day.

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.
