The project integrates solar carports with C&I energy storage cabinets and EV charging stations, forming a "solar, storage, and EV charging" system. The distributed solar power generation system has an installed capacity of approximately 92 kWp, and the energy storage system has a capacity of 430 kWh with a maximum output power of 200 kW. The PV side generates an average annual output of 76,100 kWh, yielding around 70,000 yuan (RMB) per year, while the energy storage side (two charges and two discharges) generates an average annual income of approximately 130,000 yuan (RMB). The total investment for the PV ESS project is about 1 million yuan (RMB) , with an average annual return of about 200,000 yuan (RMB) and a payback period of approximately 4.5 to 5 year.
