Case Study - SP11

The customer needed:

• A high-yield rooftop solar PV system

• Smart battery storage to cover night-time use

• A system with low maintenance and strong ROI

• Minimal shading losses and high self-sufficiency

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%)
