High Efficiency Bi-Facial Solar Cells

The high efficiency of N-type topcon solar cells is due to their unique design, which reduces recombination losses and increases the amount of light that is absorbed by the cell.

Additionally, N-type topcon solar cells come with PID-free and LID-free attributes and are less sensitive to temperature variations, making them a good choice for use in hot climates.


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.

About the WST-525 NGX-D3


Award-Winning Technology

The solar cells are crucial for the module’s output. WINAICO selects only solar cells with minimal variance. This avoids localised thermal loads (hotspots) and achieves a high energy yield even in poor light conditions.

An anti-reflective coating and degradation-free technologies increase the cells’ efficiency and ensure long-term reliability.

At the forefront of the latest photovoltaic technology, WINAICO has embraced bifacial glass-glass panels, which offer an improved temperature co-efficeint, perfect for Australia’s hot clients. These panels absorb more light for increased power generation. With no polymer backing sheet these panels truly go the distance.

Highly awarded and recognised as one of the top brands in Australia, WINAICO panels consistently outperform others in independent testing such as Desert Knowledge.

Awards include:

  • Top Solar Products (Solar Power World)
  • The Taiwan Excellent PV Award (ITRI)
  • Top brand certification (EUPD Research, 2018-2022)
  • SolarProsumerAward© (EUPD Research, 2022-2023)

Up to 30-year Warranty & 2 years System Insurance 

Peace of Mind is guaranteed with the greatest solar module protection in Australia. The 25 or 30-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 our complimentary 2-year (extendable to 5 years) insurance policy which covers the whole system against damage, loss of power and loss of income.

Our office is based in Australia, so you know if anything goes wrong, we’re here for you.

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 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.

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.

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.

Temperature Co-Efficient

The temperature coefficient has improved with each generation of solar modules. The change from PERC to TOPCon improves the temperature coefficient by another 15% – from 0.35%/°C to 0.30%/°C.

Starting from a standardized wattage of 430 watts, TOPCon modules deliver over 3% more power.
