Solar energy as a new kind of energy for its no pollution, safe and reliable, widely available energy advantages, such as more and more get the favor of people. No matter from the near future or long-dated and, no matter from the Angle of energy and environment, or from remote areas and special applications demand point of view, solar power generation is extremely attractive. So the study of photovoltaic power generation system has become both a rewarding and meaningful. Through the study of theoretical research of photovoltaic power generation system, established a complete system of photovoltaic power generation system, this paper in-depth study the photovoltaic cells under different illumination intensity, temperature, voltage, power output characteristics. In this paper, the research emphasis is the c...
