為因應近年來全球能源短缺,太陽能電池為世界各國皆積極投入的綠能產業項目之一,具有相當可觀的發展價值與潛力。為了直接接收太陽光,太陽能電池模組皆裝設於戶外或屋頂處,由於世界各地有不同的氣候條件與自然外力,如氣溫高低、積雪、陣風、以及雨水等影響。這些外在條件容易造成電池模組的破壞與鏽蝕。其中用來固定電池,架設於模組四周的鋁框在外力的影響下則會產生脫框、挫曲變形等破壞。
本文利用電腦補助軟體Abaqus建造太陽能電池模組有限元素模型進行載重分析。根據規範之負載(2400Pa、5400Pa)針對不同鋁框斷面樣式、框體高度、接觸面設置摩擦條件、電池模組架設方式等條件下操作。進而了解鋁框在各種條件下之變型模式以及應力分布等情形,初步分析結構受載之行為模式以及接觸區滑脫現象,做為設計鋁框最佳斷面之參考與方向,以增益鋁框抵抗外力或減少材料以降低製作成本。
最後於結論處給予分析結果之整理,建議較佳之框體結構與架設方式,並標示應力極值發生位置、各種模組變形外貌以及材料破壞區域,提供鋁框結構或架置系統於設計上仍需加強的參考方向。
For the energy shortage in recent years, the solar cell is one of the most popular green-industry that every country in the world is involving, and it has great developing value and potential. In order to receive the sunlight, PV modules are installed outdoors or on the roof. But the module may be damaged and corroded by the constantly changing temperature, snow, gusts and rains due to the climate differences and natural forces around the world. The supporting for PV modules is made of aluminum and will deform, and buckling due to the forces.
In this article, the finite element program Abaqus, is used to build the model for numerical analysis. In order to understand the deformation modes and the stress distribution of the aluminum frame in different conditions, different aluminum section types, frame heights, contact frictions, different specification loading and mounting methods are considered. According to the preliminary analysis of the loading behavior and the slipping distance, we can find out some of the best constructions and directions for the aluminum section design. Consequently, we can improve the resistance of the aluminum frame or reduce the use of materials to lower the producing costs.
In the conclusion, we recommend better frame structure and mounting method. Then the location of module deformation, the damaged area and where the maximum stress happens are shown. In the long run, we can provide suggestions for improving the structure and the mounting design of aluminum frames for the PV module.
