"There is a backlog of nearly 10GW of power generation components in the domestic photovoltaic market. If installed, it can generate 100 million kwh of power every three days, and it does not need any fuel." Zhou Lang, Dean of the photovoltaic Institute of Nanchang University, told Xinhua News Agency recently that the state should timely introduce relevant policies to encourage grid companies to provide supporting facilities for renewable energy power grid, so as to accelerate the start of domestic market and optimize energy structure.

It is understood that China's photovoltaic cells and modules shipped more than 50% of the world, but the installed capacity of photovoltaic power stations is less than 5% of the world. Affected by the European debt crisis and the US double reaction, there is a growing call for the industry to accelerate the launch of the domestic market. On August 1, 2011, the national development and Reform Commission issued the national unified photovoltaic on grid price policy, which is regarded as good for the industry. However, it has lasted for one year, and the progress of on grid tariff policy is not ideal because of "responsibility and no incentive".

Zhou Lang said that due to the instability of solar photovoltaic power generation due to the changing radiation and weather, the grid system faces many additional investment in technology, equipment and management. This not only increases the management burden and safety risk of power grid enterprises, but also reduces their electricity sales. Power grid enterprises lack enthusiasm. So far, various incentive policies and plans have been issued, especially the lack of corresponding support and incentives for grid enterprises.

"If a set of photovoltaic power generation device is built on the roof of a supermarket, its service life is conservatively calculated to be 25 to 30 years, and the power generation cost is about 0.7 yuan / kWh. Compared with the civil electricity price in some areas, which has reached 1.5 yuan / kWh, it has full market competitiveness." "Although there is a viable market model, there are still obstacles to the start-up of the domestic market due to the fact that redundant power generation cannot be sold in parallel," Zhou said

Zhejiang Xinxiang photovoltaic support manufacturers suggest that the photovoltaic power generation needs to be delivered after it is put into the "network". We can consider subsidizing power grid enterprises according to the purchased renewable energy power, encouraging power grid enterprises to support the renewable energy power grid; at the same time, we can simplify the administrative approval procedures for the construction of various local micro networks and small power stations, and focus on supporting some demonstration projects of rural photovoltaic power generation, so as to effectively accelerate the start of the domestic market and develop clean new energy.
