Good efficiency for building powerful systems

Works well in all kinds of weather

The panel shows optimal yields even at high temperatures and in low-light conditions. Korean PV modules perform well in cloudy weather and in the winter. Extreme weather conditions aren’t a threat; solar cells are protected by high-tech aluminium alloy frame, which is certified for high snow (5400Pa) and wind loads (2400Pa).

Reliable investment protected by warranties

Q CELLS panels come with a 12-year product warranty and 25-year performance warranty. The module doesn’t lose more than 2% of its power in the first year of service. After that the annual degradation rate is no more than 0.54% of power output per year. The panel retains over 85% of its output by the end of year 25.
