I. Overview

Although there are many ways to use solar energy, it is not suitable for China's national conditions, such as ultra-high-power solar power stations and home rooftop power generation. The only simplest and easiest to implement is solar street lights. The total number of street lamps in China exceeds 100 million baht. As long as 60 million gongs are converted into solar street lamps, the annual electricity saved exceeds the power generated by a Three Gorges hydropower station. If the 20 million new street lamps added in the future are all converted to solar street lamps, it will be a Three Gorges hydropower station in three years. The effect of energy conservation is very impressive, and there is no need to mobilize the power of the whole country to build, so that the power of local governments at all levels and the power of all relevant enterprises can be completed.

The composition of solar street lights is very simple (Figure 1).
