At present, the national related energy planning has put forward the extraordinary development goal for the distributed photovoltaic. "Electric Power Development" Thirteen-Five "plan" proposed, to "2020, solar power generation machine to reach more than 110 million kilowatts, distributed photovoltaic more than 60 million-kilowatt."
To ensure the realization of the goal, the state always takes the positive attitude to the distributed photovoltaic power generation system, and the state issued a series of policies to support, the most typical is the price policy support. In addition to price support, February 27, 2013, the state power grid held a press conference to the community to release the "Views on the distribution of power grid services" to solve the problem of distributed photovoltaic grid-connected. January 2014, National Energy Bureau released the "Notice on National Energy Bureau of the 2014 annual PV generation of new building scale", determined the 2014 PV new Construction Scale. In the same year, September 4, the National Energy Bureau issued "Notice on the further implementation of the relevant policy of distributed photovoltaic", in order to promote the development of distributed photovoltaic, the policy make a major adjustment on its connotation and extension: can choose the mode" spontaneous for private and the extra electricity for power grid " or "full electricity for power grid".
