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.
