The Approach

We proposed a Q CELLS-based hybrid solar and battery solution with 18 high-efficiency panels and smart battery storage. Thanks to a dual-aspect layout and shading consideration, the system is designed to achieve a 93% self-sufficiency rate while generating 5,910 kWh annually.

System Overview:

18 x Q CELLS 435W panels (7.83 kW total)
1 x Q.VOLT H4.6S inverter
1 x Q.HOME CORE H4 battery (6.86 kWh usable)
Estimated Generation: 5,910 kWh annually
Self-sufficiency with battery: 93%
Shading losses: 7% (performance guarantee ≥90%)
