Product Description


When you buy from WINAICO, you are buying products from a manufacturer specialising in premium-quality solar panels.

As a Taiwanese module manufacturer with German and other subsidiary companies around the world, WINAICO is positioned amongst top brand manufacturers with a high-quality product from an automated production line. The parent company, Win Win Precision Technology Co., Ltd. has its origins in the semiconductor sector, which is subject to the same quality management demands as those applied in the solar industry.

With leading-edge system technology and process expertise originating from the semiconductor industry, WINAICO is setting qualitative benchmarks on the PV market, as can be seen with their highest in class performance at the Desert Knowledge Solar Centre in Alice Springs. More Info.

The WINAICO WST series high performance photovoltaic panels are each fitted with 60 highly efficient 156 x 156 mm solar cells and through the application of high-grade semiconductor silicon, achieve outstanding energy yields. The WST‐series is available in either 245 W or 250 W and features a silver 35 mm single‐walled frame and a new junction box. Exclusively positive power tolerances and a 10 year product warranty insure that your investment will pay off year after year.




  • Use of top quality brand components exclusively
  • Linear performance guarantee over 25 years
  • 10-year product warranty
  • Positive only tolerances of 0/+5 Wp
  • Anti-PID technology - The use of high-quality encapsulation material and most modern equipment secure a permanent production of PID-resistant modules.
  • Hot-Spot protection - A 100% proof of all cells, using an applied back current, enables WINAICO to sort out defective Hot-Spot cells.
  • Light induced degradation (LID) - The use of high-quality raw materials leads to a low degradation of the nominal power of a panel at the beginning of its lifetime.
  • Passed Fire test MST 23 of IEC61730, Ignitability Testing following DIN EN ISO 11925-2, making it suitable for installation in Australian conditions.

1 STC (Standard Tect Conditions): Irradiance 1000 W/m2, cell temperature 25°C. AM=1.5

2 NOCT (Nominal Operating Cell Temperature): Irradiance 800 W/m2, ambient temperature 20°C, AM=1.5, wind speed 1 m/s.

2 The power output shall not degrade more than 3% in the first year, The average annual power output degradation shall not exceed 0.7% each year in the following 25 years, ending with 80.2% at the end of 25 year.

We also have solar regulators available to suit this solar panel, but please note that as it is possible for a solar panel to exceed it's rated current output in some conditions, a 24V solar regulator with a rating of at least 11.0 Amps would be recommended for this size solar panel.
