If the load is required to be supplied with power at any time, an energy storage device is required. Secondly, for photovoltaic power generation, the illumination energy density is low, under standard conditions, the intensity of solar radiation received on the ground is 1000 w/square meter, and a large area is required to be occupied when the solar photovoltaic power generation is used in large-scale practice. Thirdly, the initial investment cost of the photovoltaic power station and the wind power plant is high. Fourth, photovoltaic power generation and wind power generation require government subsidies. Fifthly, the service life of the photovoltaic panel is about 25 years, the service life of the wind driven generator is about 20 years, and the service lives of the photovoltaic panel and the wind driven generator are short.
