Low degradation rate

Anti LID Technology targets light induced degradation, vastly improving system performance. Compared to conventional monocrystalline cells that lose much of their initial capacity, Q.PEAK DUO BLK-G6 has a significantly lower degradation rate.

19% Superior Efficiency

This new Q CELLS model is a monocrystalline panel that converts sunlight into electricity with a 19% efficiency. What’s more, Anti LID Technology makes this efficiency long-lasting, tackling the threat of degradation.

A panel that will weather any storm

High-tech black aluminium frame is certified for high snow and wind loads. The model’s rear and front sides can handle 4,000 and 5,400 Pa loads respectively.

Performance Warranty

Low degradation over the next 25 years: the output decrease will be limited to 2% in the first 12 months and won’t go above 0.54% annually after that. After 25 years the panels will work at no less than 85% of nominal capacity. The manufacturer also offers a 12 year product warranty.

None of the fears I had about going solar came true. The store handled my order very professionally and they didn’t give me any surprises

Excellent build quality and impressive output. The modules are 50 ft away from the inverter and the system works great. Would recommend to a friend

Unfortunately, no, we only sell the equipment.
What do they mean by ‘engineered in Germany’?
