碩士 === 國立高雄科技大學 === 電機工程系 === 107 === With the advancement of modern science and technology, human demand for energy is also increasing. The main energy used by human beings comes from fossil energy, but the fossil fuel reserves are gradually depleted due to long-term large-scale exploitation, and the environmental pollution caused by fossil energy and the problem of global warming are becoming more and more serious. Therefore, seek a sustainable, clean and no Polluted alternative energy sources cannot be neglected. Solar energy is an inexhaustible source of energy that does not pollute the environment. Solar photovoltaics use solar cells to convert solar energy into electricity through photoelectric conversion. Perpetual energy, it is also the most mature and most potential energy in renewable energy. Based on process and cost considerations, the general commercial product efficiency of solar cells is only 13% to 17%. Therefore, this paper mainly The discussion is based on the improvement of equipment outside the solar cell to improve the overall power generation efficiency of the solar photovoltaic. This article focuses on the power generation efficiency improvement and improvement of a large-scale solar photovoltaic system (PV) application in China. The paper first introduces the principle of solar energy application and power generation, the principle of solar power tracking and positioning, the system of chasing after the sun, and the sale of solar energy. Technical points. The solar photovoltaic power generation efficiency improvement scheme adopted in this study has five items: (1) using an amorphous transformer; (2) removing the anti-reverse iii diode; (3) using a direct/AC converter (Inverter) built-in Two sets of Maximum Power Point Tracking (MPPT) controllers are connected in parallel; (4) solar cell equipment ventilation improvement; (5) installation of sprinkler cooling equipment. The paper will detail the equipment differences before and after the improvement of each scheme, and evaluate the power generation efficiency and improvement results of each scheme. Finally, compare and analyze how to improve the efficiency improvement measures, and make conclusions to provide further improvement for the operators. For reference, overall, this study can improve solar photovoltaic power generation efficiency by about 4.6%.
