How many MW is a photovoltaic power station?

Large photovoltaic power stations can be equipped with 100MWh energy storage power stations. The battery type is Lithium iron phosphate, the power of the station is 50 MW, the annual utilization hours reach 800 h, and the power generation capacity is 800 million kilowatts. Other operational data of the power station are detailed in Table 3.

Does energy storage bring more revenue for PV power plants?

Thirdly, energy storage can bring more revenue for PV power plants, but the capacity of energy storage is limited, so it can't be used as the main consumption path for PV power generation. The more photovoltaic power generation used for energy storage, the greater the total profit of the power station.
