The battery, or energy storage system, stores electricity when the power plant is producing energy. When electricity production decreases or stops, you can use electricity from the battery. Depending on the size of the battery, there is easily enough electricity for the entire day or, for example, for production shutdowns. You can also sell excess energy back to the grid as a reserve market and with the help of our demand response services. We are BYD and enershare offical partner.

A photovoltaic system is a profitable investment because it will generate a return of up to 5-15% of the amount invested in the system over a period of decades, or even a year.
