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