HJT Cell Technology

Heterojunction (HJT) technology combines the best of crystalline silicon and thin-film solar cells, delivering superior efficiency and reliability. WINAICO’s HJT cells feature ultra-thin layers of amorphous silicon on both sides of a high-purity monocrystalline wafer, dramatically reducing recombination losses and improving low-light performance. With an exceptional temperature coefficient and slower long-term degradation, HJT ensures consistently high output even in Australia’s hottest climates.

 

Bifacial Efficiency & Durability

The glass-on-glass construction significantly improves the panels’ durability, improved energy conversion efficiency, seamless aesthetic integration, fire resistance, efficient heat dissipation, recyclability, and advanced temperature coefficients make them a compelling choice for both commercial and residential systems. 

By eliminating potential vulnerabilities such as delamination and corrosion, glass-on-glass panels offer a longer lifespan with reduced efficiency loss over time.

These panels have undergone rigorous testing to ensure unmatched safety and performance, perfect for Australian conditions prone to bushfires, cyclones, and hailstorms.

Temperature Co-Efficient

Bifacial Solar Panels are less sensitive to temperature variations, reducing the impact of temperature to ensure optimal power output even in challenging hot climate conditions. The change from PERC to TOPCon improves the temperature coefficient by another 15% – from 0.35%/°C to 0.30%/°C. Starting from a standardised wattage of 440 watts, TOPCon modules deliver over 3% more power.

The Glass

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

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 Cells

The performance of a solar panel starts with the cells.

WINAICO’s HJT technology uses high-efficiency bifacial cells that combine crystalline silicon with ultra-thin amorphous silicon layers, reducing energy loss and boosting low-light performance. The result is an advanced cell structure with excellent thermal stability, low degradation, and outstanding real-world energy yield.

The Junction Box

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.

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.
