"Photovoltaic + Energy Storage + EV Charging" is the most tacit and potential combination. Photovoltaic can be everywhere, and application scenarios cover almost all industries, such as ground power stations, industrial and commercial roofs, household roofs and so on. New energy vehicles are the inevitable trend of future automobile development. The combination of energy storage and photovoltaic, charging pile application scenarios, on the one hand, helps photovoltaic solve part of the generation redundancy and grid connection problems in the application process, and the other part gives play to the combination advantages to drive the multi-directional development of photovoltaic, energy storage and EV charging.
