At the same time, there are nearly 2 billion people in the world who do not have access to normal energy supply. Renewable energy can change the energy structure of mankind and maintain long-term sustainable development. The hottest new energy field is solar energy. According to statistics, the energy generated by the sun shining on the earth for one hour is enough to meet the world's current energy needs for the whole year.
