This paper is mainly about the use of solar energy in life to make a summary, and how to improve the utilization of these aspects to make suggestions. Sunlight transmits electricity to the earth all the time. If the total radiation power from sunlight to the earth is converted into power generation power, it can reach 1.77× kW, which is several hundred million times larger than the current global per capita consumption of electricity. There are not only a lot of sunlight, but also all green energy sources from sunlight, such as wind energy, tidal energy, microbial energy, hydraulic energy, etc., all belong to renewable energy sources. As long as there is sunlight, renewable energy sources are as constant as sunlight. In the process of the efficient development and utilization of solar energy, the photovoltaic utilization of nuclear energy has become the fastest progress around the whole world in recent years, the most vitality of the scientific research field.
