Lamination Design of Photovoltaic Solar Panels

Abstract

Solar power is inexhaustible and has become the most appreciative choice in the world. With development stage of solar modules, solar panels are conducted by the relevant reliability tests to ensure long lifetime and power generation efficiency. During the lamination process of solar modules, the performance of the solar panels has been greatly relevant with the degree of crosslinking for ethylene-vinyl acetate (EVA) sheet. The degree of crosslinking for EVA sheet is obtained by using the extraction method to measure the gel content of EVA sheet. Motivated by lamination tests on solar panels, this study first constructed the statistical model with extreme value residuals to describe the relationship between the degree of cross-linking for EVA sheet and lamination time. Then, under the specification upper and lower limits of the degree of cross-linking for EVA sheet, the optimal lamination time of solar panels will be derived, and the optimal sample allocation for measuring EVA sheets destructively will be addressed. 關鍵詞：EVA sheets, the degree of crosslinking, chemical extraction method, optimal lamination time, specification limits.
