被動式太陽能追日系統之創新設計與製作
Innovative Design and Manufacture of Passive Sun Tracking Systems
摘要
為了改善太陽能追日系統的實用性及發電效率，本研究搜尋現有太陽能系統與太陽能追日系統之相關文獻資料，分析太陽能技術演化趨勢、追蹤技術與控制方法，應用TRIZ(Theory of Inventive Problem Solving)創新理論與工具，藉由技術矛盾、物理矛盾與理想化設計等工具，進行一系列創新方案設計，比較各創新方案優缺點後，擇優製作雛形，並於太陽日照下，測試追日系統雛形之可行性與發電效率。 本研究研製不使用電力控制與馬達驅動的被動式太陽能追日系統，使用者可以藉由季節(春分、夏至、秋分與冬至)調整南-北向之控制軸，並藉由水浮力的物理特性，調整東-西向之太陽能板角度變化，使太陽能板能夠垂直日照角度，提升被動式太陽能追日系統的發電效率。 經實地測試比較，發現本設計方案之被動式太陽能追日系統電壓，約較固定式太陽能系統有效提升約3.9%電壓發電效率。

In this study, we examined existing literature on solar energy systems and sun tracking systems and analyzed the evolutionary trends of solar energy technology, tracking technology, and control methods to enhance the practicability and power generation efficiency of sun tracking systems.technical contradiction, physical contradictions, and ideal final results were used to design a series of innovative solutions. After comparing the advantages and disadvantages of the solutions, a prototype was constructed based on the optimal models and tested in sunlight to determine the feasibility and power generation efficiency of the sun tracking prototype. In this study, a passive sun tracking system without power control and non motor drive was developed. The south-north control axes can be adjusted through the seasons (the vernal equinox, summer solstice, autumnal equinox, and winter solstice), and the angle changes of the east-west solar panels can be adjusted through water buoyancy physical characteristics to ensure they maintain a vertical direction to the angle of sunlight, thereby improving the power generation efficiency of passive sun tracking systems. After testing, the voltage of the passive sun tracking system prototype was observed to be approximately 19.94V, whereas the voltage of fixed solar energy systems was approximately 18.99V. This indicates that the innovative solution developed in this study effectively increased the power generation efficiency than fixed solar energy systems by approximately 3.9%.
