It depends on your energy usage. For a typical US home with a $200/month electric bill, you'd need about 20 panels (410W each) for an 8 kW system. Use our quick estimate tool for a personalized calculation.
The Q.PEAK DUO ML-G11S 410 has a module efficiency of 20.6%, which means it converts that percentage of sunlight into electricity. This is competitive for residential solar panels.
QCells offers a 25-year product warranty and 25-year performance warranty. Annual degradation is guaranteed not to exceed 0.55%.
Key strengths: German engineering quality, excellent all-weather performance, strong brand reputation, competitive price. Considerations: Lower efficiency vs newer N-type panels, standard PERC technology. It's a solid budget-friendly option from a Tier-1 manufacturer.
