China has become one of the biggest energy-consuming countries in the world. Currently, the oil price has reached its historical price. It is because the two largest developing countries, China and India, are hungry to energies and resources to feed their high speed growths. However, the negative impact of use of resources, that is pollution, has caused a series of social problems and is seen as one of critical issues which can restrict Chinese economic development. Therefore, an alternative clean-energy and renewable energy, such as solar PV, is highly recommended by Chinese government.
