The use of solar photovoltaic power generation is the irreversible trend of change. China has become the world's second-largest electricity consumer market after the United States, with demand growing at the highest rate in the world. However, due to the shortage of petroleum energy and the emergency of coal resources, the existing power generation methods can not meet the power consumption demand far. The promotion of solar power generation is quite urgent and the market potential is huge. For the market, accelerate the development of solar cell industry will be promising.
With the increasing depletion of the Earth's resources and rising costs of investment in basic energy, various security and pollution risks are ubiquitous. In this way, solar lighting products with the popularity of solar water heaters should be born, where we solar lights and the effect of the use of electricity for practical comparison.
