Rugged Corners

WINAICO's WST modules are built with rigid internal L-keys creating one of the strongest panels on the market.

We've worked with leading research institutes to continually test and improve mechanical resilience. Our frame is capable of bearing more than 1030kg of snow and can withstand winds up to 220km/hour.

Long Term Protection

Peace of Mind is guaranteed with the greatest solar module protection in Australia. The 25-Year Product and Performance Warranty is the legal assurance that your panels will perform for their lifetime on your home or business. This is on top of the complimentary system insurance for all solar sold in Australia.

Only WINAICO provides 3 complimentary protection policies for your solar modules.

Automation & Testing

Our state-of-the-art automated production line with precision instruments is overseen by technical experts resulting in the highest quality panels.

Our panels are tested with electro-luminescence equipment which checks for defects that cannot be seen with the naked eye before and after lamination for consistent excellence.

High Efficiency Cells

To achieve quality you have to start with quality, which is why our cells are made in Taiwan, home of the semi-conductor.

WINAICO selects only mono crystalline solar cells from premium manufacturers with PID-free and LID-free technologies. With our new half cell, 9BB design, the GEMINI solar modules are pushing the limits of power density in modules. Minimal variance prevents hot spots and gives a high yield in low light conditions.

3-in-1 Insurance Policy

Our 3-in-1 insurance provides security to your investment. All WINAICO modules include 2 years free insurance coverage, extendable to 5.

Essential protection for the complete installation against any kind of material damage including fire, natural disasters such as storms and hail, theft and even animal damage.

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 corner pieces ensure the best transfer of tension.

The Solar Cells

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

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.
