全球氣候劇烈變化，地球能資源匱乏成為最迫切的問題，建築為地球環境最龐大的建設，所消耗的能資源相對也較多，建築物導入太陽能模組可達到節能效益之目的，並對地球永續環境有極大的貢獻，然而PV模組溫度上升，會使得室內還境溫度升高，空調使用率上升，反而沒有達到節能效益，並且溫度使得PV模組效率下降，所以PV模組導入建築物必須有效的將室外熱量阻隔並且將模組內熱能帶走，才能達到有效的節能效益，本研究將針對兩組PV模組進行溫度預測，有加空氣層的PV模組及一般PV模組，探討受到日照的模組溫度，並且實驗與模擬進行驗證。
太陽光電系統的電力產生量，幾乎是與太陽能電池的面積以及在太陽光電池表面的太陽輻射能量成正比，也與太陽能電池的溫度有關。來自太陽的輻射能量，除了被太陽能電池轉換成電能，其餘的能量轉換成為熱能，會讓太陽能電池的溫度上升，溫度會高於週遭的氣溫。一般非晶矽薄膜 (amorphous thin film) 太陽能電池的效率溫度係數 (temperature coefficient) 是0.26 %/oC，也就是說溫度對太陽能電池效率的影響大約是溫度每升高1 oC時，效率下降0.26%，所以溫度的對於PV模組效率有絕對的影響，並藉由商用軟體Fluent了解整體PV內部的熱傳行為。
本研究透過基本假設與統御方程式加以解析，並且利用ANSYS Fluent有限數值分析軟體進行分析。研究中使用非結構四面體網格建立網格模型，並建構出一套BIPV模擬系統，探討在各個不同結構狀態下，受到各種不同日照下及不同風速下，其結構溫度分布情形。在本文的最後於進行實際量測溫度，來加以驗證所建立之分析方法的可行度，經由比對驗証實驗的結果與模擬分析的結果，証實本文所建立的溫度分析方法有相當不錯的準確度。

Accompany with the prosperous economy and technology growth, the speed of the energy resources consumption keep growing with each passing day. Under the restriction of limited resources, energy crisis has become a prior problem toward the industrial development and population growth. Buildings are the most giant structures in the world; therefore the expense of energy resource was even more. If we can lead the solar module into buildings, not only the result of energy saving but also the eco-village is easy to be foreseen. However, once the temperature of PV module increasing, the indoor temperature was ascending simultaneously. In order to cool the indoor temperature, people tend to turn on the air conditioner; consequently, the energy saving purpose was ruined. Besides, the increasing temperature may also reduce the efficiency of PV module. In other words, only isolate efficiently of the outdoor heat and reduce comprehensively of the heat generated from the mould can achieve the purpose of energy saving. This research will compare PV module with air area with general PV module to explore the temperature variation of sunlight impact and proof via experiment and simulation.
The electricity level which was generated from solar power system was almost with positive relationship with the surface scope of solar battery and the solar radiation energy on the surface of solar battery. Also, it’s related to the temperature of the solar battery itself. Except for being turned into the electricity power, the left-over of the radiation energy which was emitted by the sun was turned out to be heat afterwards. This heat will result in the temperature increasing of the solar battery. Moreover, this temperature is usually higher than the atmospheric temperature. The temperature coefficient of amorphous thin film cell is about 0.26 %/oC. Once the temperature increase for 1 oC , it may cause the efficiency of the solar battery to decrease about 0.26 % than usual.
Aside from the basic hypotheses and governing equations, this research will also use ANSYS Fluent Finite Element software to assay. In order to explore the structure temperature distribution conditions under the premises of different sunlight and wind velocity with different structure condition, we will use unstructured tetrahedron mesh to build the mesh model and construct a BIPV simulation system.
Considering the feasibility of the analysis method, in the final part of this thesis, we’ve measured the temperature of BIPV outwall and compared the experimental result with the simulated analysis consequences. Ideally, the outcome of this comparison reveals a good accuracy of our temperature analysis methods.
