00 kW system of 20 panels at 400 W each would cover 104% of your 10,500 kWh annual electricity use. It would produce 10,936 kWh/year and need about 560 sq ft of unobstructed south-facing roof space (including fire-code.

A: Most residential panels range from 250W to 400W, with 300W-350W being common for newer models. Calculate your annual kWh needs, then divide by your area's solar production ratio.

So to generate 15kwh, you'd need around 8 × 400W panels with 5 sun hours/day. Higher efficiency panels (20–23%) convert more sunlight into electricity per square meter. This matters if roof space is limited. Real-world losses (wiring, inverter inefficiency, dust) are typically.
