Solar energy has advantages but also disadvantages, mainly low energy density, large floor area, low conversion efficiency, intermittent operation, great influence of natural conditions and climatic environmental factors, strong regional dependence, high system cost, crystalline silicon cells. This process is very polluting and energy-consuming.
Sichuan is a mountainous city. The geographical conditions are not good, there are not many plains and the climate is hot and humid. Plus, the cost of a kilowatt. the electricity hour is very high, so it is not cost-effective.
