高雄地區光電照明系統的特性分析

以前對於光電系統的應用研究大都只能作儀器系統的裝配與量測，但本文多樣地收集研究資料，使裝配前的系統分析與最佳化的選擇變成可能。據此，本研究以高雄地區的環境為例，作太陽能光電照明系統的特性分析。本文分析了四季太陽運行的路線，並且依它仰角和方位角的不同而算出各個時間的發電量，從而可以判斷此光電系統的充放電情形。關於太陽能模板吸收太陽輻射的總能量方面，本論文採用非等向模式。本研究設計了一個配置發光器，由電瓶、光電模板、發光器及加熱器組成的光電系統。白天時，由太陽能光電模板吸收太陽輻射轉換為電能，並將電力儲存於電瓶內，於夜間無光能時，提供電力供發光器使用。而在白天時，如果電瓶充滿電力達到飽和狀態時，此時生產的電力也不浪費，它被用來供加熱器使用，此加熱器為可變電阻，它的作用不光是將多餘的電力用做加熱；同時，它也可以調節整個系統維持最大功率。

Studies about photovoltaic system presented by previous investigators were chiefly concerned with experiments, but this study focuses on the characteristic analysis of photovoltaic lighting system located in Kaohsiung. It analyzes the situation of charge and discharge and takes into account the season effect. The simulation results relating to the difference of the four seasons are presented and discussed. The total energy of solar radiation absorbed by photovoltaic module is predicted by the model for anisotropic sky. In this paper, we have designed the photovoltaic system with light emitters to operate. The photovoltaic system is composed by photovoltaic cells, batteries, light emitters, and resistance heater. In the daytime, the solar radiation that is absorbed by the photovoltaic module is converted to electricity and stored in batteries. At night, the batteries provide power to the light emitter for use. During the day, if the battery is recharged to the full state, the power is not wasted but is used for heater. The heater is a variable resistor. It is used for not only the excess electricity heating but also the maximum power maintaining.
