Understanding grid connected photovoltaic systems
Distributed PV power generation system
Is a grid connected power generation system which uses solar modules to convert solar energy directly into electrical energy. The system is located near the user and can be used locally.
To 10 thousand volts and below voltage level access to the grid, and is divided into 10KV grid connected, 380V grid connected, 220V grid connected three. 10KV user side single and network outlets, the total installed capacity of not more than 6 MW, 380V user side, single and network outlets, the total installed capacity of not more than 400KW, 220V user side single and network outlets, the total installed capacity of not more than 8 kilowatts.
At present, the most widely distributed photovoltaic power generation system is built on the roof of the building photovoltaic power generation projects. Such projects must be connected to the public power grid, together with the public power grid for the power supply for nearby users, the principle is "to generate electricity nearby, near the grid, the nearest conversion, the nearest use.
National Policy
for distributed photovoltaic power generation (part)
In August 30, 2013 the national development and Reform Commission issued the "notice" on the play price leverage to promote the healthy development of the PV industry, for distributed photovoltaic power generation projects, carried out in accordance with the electricity price subsidies policy, electricity subsidy standard of 0.42 yuan per kilowatt hour.
In January 28, 2014, the state Power Grid Corp issued the notice on the management rules of distributed power grid connected services, which unified and standardized the grid connected management of distributed photovoltaic power generation projects.
