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.
Solar cells are what convert sunlight into electricity. The characteristics of a solar panel are determined by the quality of the cells. WINAICO only uses highly efficient cells with the lowest possible variance in the manufacturing process, both in their electrical output and consistency of colour. WINAICO is very careful with its choice of cells and reject any that do not meet our high standards.
The Junction Box
The Junction Box houses the electrical components. It contains diodes which protect the module against partial shading issues.
WINAICO’s Junction Boxes are rated at the protection class IP67, so provide optimum protection against moisture, dirt and UV radiation. You can be confident that nothing is getting 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.
We only use high PET backsheets, renowned for their excellent weather resistance. Our suppliers have proven their capabilities to provide 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.
