How It Works

The sun shines on the special heating absorption board. The air absorbs heat and is blown into your room by a 12V fan powered by the solar photovoltaic panel. On sunny days, the temperature of the injected air is 5–30°C higher than the outdoor temperature. The system starts and stops automatically based on sunlight intensity – zero maintenance required.

Save Money & The Planet

Estimated energy supplement: 250 kWh/unit/year. Most customers see payback within 2–3 years. After that, it's pure savings for the next 20 years (panel lifespan).

Using solar air heating reduces greenhouse gas emissions and your dependence on fossil fuels.

Frequently Asked Questions

Does it work on cloudy days?

Yes. The fan can automatically switch to electricity on cloudy/rainy days to provide ventilation (power consumption: less than 10 kWh/year).

Do I need an electrician?

No. The OS10 is DIY-friendly. Only a wall hole (135mm) and basic tools are needed. Most customers finish installation in 1 hour.

Can it prevent basement mold?

Yes. Continuous ventilation removes moist air and prevents mold growth. The OS10 is ideal for damp basements and wooden houses.

What maintenance is required?

None. The system runs automatically based on sunlight. The PV panel lasts 20 years, and spare parts (except the panel) can be replaced in 30 minutes.
