Since twenty-first Century, our country's social economy has been developing rapidly, the demand for electricity is also rising, but now the energy is broken, the supply of electricity is always unable to keep up, and the induced gas emitted by a large amount of thermal power has also caused the pollution of the environment, and we need to use new energy to solve this problem. Some problems need solar streetlights. China has a rich solar energy resources, using solar energy as a solar energy street lamp, applied to outdoor lighting, is to provide a good solution for the implementation of energy conservation and emission reduction in the country. If we continue to use ordinary street lamps, not to say that power supply is not up, the power consumption will exceed 1000 degrees a year, consuming the standard. The more than 400 kilograms of coal will cause more environmental pollution.
