According to a user's power requirements, photovoltaic modules can be individually used or connected in either a series (to meet voltage requirements) or in parallel (to meet current requirement) to form a power supply generation system. SEC photovoltaic modules have high-area-ratio power, durability, and reliability. The average service life is 20 years.SEC modules are composed of solar cells with high conversion efficiency, an EVA sheet, solar glass, and a TPT back sheet compounded from flouro-plastic and Dacron. The module is made with reliable welding technology and a high-vacuum heating lamination process. It is also equipped with an anticorrosion-treated aluminum alloy frame and watertight terminal box. As a result, it has ultraviolet aging resistance and wind resistance of up to 2,400MPa.Inner packing:Carton
