The frame holds the panel together. It protects the internal components, taking the stress of mechanical loads.

WINAICO’s frame maximises stability and protection against material fatigue. Built without screws or small L-keys, our strengthened corner pieces ensure the best transfer of tension.

The characteristics of a solar panel are determined by the quality of the cells.

WINAICO’s GEMINI technology uses high-efficiency half-cut solar cells with 16BB to reduce internal resistance and conduction losses. The results are highly efficient solar cells with low working temperature and low power degradation.

A GEMINI module uses 3 High Quality junction boxes to hold bypass diodes that protect the module against partial shading.

WINAICO uses IP68 junction boxes with genuine MC4 EVO2 connectors to provide optimum protection against moisture, dirt and UV radiation. You can be confident that nothing gets into a WINAICO Junction Box.

EVA (ethylene vinyl acetate) films are used in lamination to encapsulate the internal components.

EVA film must protect the panel throughout its entire service life. Low quality films may discolour, delaminate or otherwise degrade. WINAICO films cross-link to at least 85%, a decisive indicator of quality, and ensure permanent protection of the cells.

The backsheet is the physical and electrical barrier which protects the solar cells, wiring and other components.

WINAICO uses a combination of UV and temperature cycling tests to validate the backsheets for reliable protection throughout the entire 25 year service life of a solar panel.
