The glass closes the front protecting the internal components. It must be resistant to impacts and scratching to allow maximum power generation.
WINAICO only uses highly transmissive glass with a low iron content and anti-reflective coating, ensuring maximum absorption in low light. Our glass is extensively tested to resist mechanical loads and temperature changes.
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 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 9BB to reduce internal resistance and conduction losses. The results are highly efficient solar cells with low working temperature and low power degradation.
The Junction Box
A GEMINI module uses 3 in 1 junction boxes to hold bypass diodes that protect the module against partial shading.
WINAICO uses IP68 junction boxes with genuine MC4 connectors to provide optimum protection against moisture, dirt and UV radiation. You can be confident that nothing gets into a WINAICO Junction Box.
The EVA Film
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.

Cutting Edge Technology
The solar cells are crucial for the module’s output. WINAICO selects only solar cells with the highest efficiency level. An anti-reflective coating and degradation-free technologies increase the cells’ efficiency and ensure long-term reliability.
In order to spread the load on the cells in the module evenly, WINAICO selects cells with minimal variance before production and thus avoids localised thermal loads (hotspots) and achieves a high energy yield even in poor light conditions.
