Generating solar energy for self consumption and the surplus energy is in jected into the national grid
On grid photovoltaic power generation system refers to the installation of photovoltaic panels on the roof of household buildings. The system absorbs solar radiation to generate DC power. After DC is converted to AC, it is merged into the national grid. The user side adopts the operation mode “generating electricity by oneself and the surplus part is merged into the national grid
Photovoltaic module : A power generation unit that converts solar radiant energy into DC power output through the “photovoltaic effect”.
Inverter : DC to AC unit, which converts the DC power generated by PV modules into single-phase or three-phase AC power that meets the quality requirements of the power grid.
Subsidized meter : The total energy metering generated by the distributed system, according to which electricity subsidy is given by the country.
Two-way electric meter : The distributed system generates electric energy except for industrial and commercial enterprises and household electricity. The surplus part is merged into the national grid to sell electricity. When the power generated by the distributed system is not enough for industrial and commercial enterprises and households to use, they can buy electricity from the country. Two-way electric meter is needed to achieve the sale and the purchase of electricity.
