由於近年來能源問題,逐漸受到各國所重視,而太陽能是一種免費、無污染且又取之不盡、用之不竭,是一種可以利用來發電的一種相當好的能源。而目前的太陽能發電效率普遍都不高,所以如何增加太陽能發電系統的發電效率是值得研究的。由於太陽會隨著四季變化,而使太陽會向南偏移,而太陽能板如能一年裡都與太陽成垂直時,其接收日照強度是最好的。所以要去量測出太陽能陣列在不同的仰角角度時,其發電量為多少,並找出太陽能板的最佳裝設仰角角度,使其發電效率達到最大。並藉由不同型式的DC/AC轉換器對太陽能發電系統有何影響,其轉換效率的差異,以及太陽能發電系統與DC/AC轉換器的連接方式(集中型,與模組成為一體的,一串陣列連接,多串陣列連接)對轉換效率的差異做一分析。
Because the solar energy is free, no pollution, inexhaustible in supply and always available, it is good for generating electrical power. At present, the efficiency of solar cell is quite low, how to make it to absorb maximum power from sun is very important. Since the sun moves with seasons, the solar array should perpendicular on sun all the time to receive the maximum radiation. We measure the solar power at different face angles and to find out the best face angles. Also analyze the effect and efficiency of the solar power system for different DC/AC converters and connection types.
