China's solar energy capacity has enhanced significantly over the past two decades, and this source of energy is playing increasingly vital role in China's power generation. This study first explained the mechanism of the global value chain and its uses, and then a photovoltaic (PV) system was investigated. We also studied China's potential and economic viability of solar photovoltaic power, because the most significant problem solar PV systems is currently facing is to finance and find an investor to carry out the projects. It was found that the cost of manufacturing and purifying silicon in all solar panel producers (USA, China, Taiwan, and Malaysia) is nearly equal, because silicon is found to be abundant in all countries, and its purification method (polycrystalline method) is almost similar in all four countries.
