It is connected to the power grid and transmits electricity to the grid. Photovoltaic power stations are green power development energy projects that the country encourages the most. Photovoltaic power generation products are mainly used in three aspects: one is to provide power for places without electricity; the second is solar daily electronic products, such as various solar chargers, solar street lights and various solar lawn lamps; the third is grid-connected power generation, which has been widely promoted and implemented in developed countries.
