In recent years, household rooftop photovoltaic will become the trend of household electricity consumption. The installation of a household photovoltaic system can greatly reduce the expenditure of household electricity costs, and the extra electricity can also be connected to the Internet, increasing an additional income for the family.

Cost reduction and efficiency improvement and technological innovation are the theme of the development of the domestic photovoltaic industry. Photovoltaic enterprises compete to offer more efficient battery products. Improving conversion efficiency will still be the main direction of the upstream and downstream photovoltaic industry chain.
