Technical FAQs 4

How much power does a solar system generate?

Desired Solar System Power Output * (kW) How much power do you want your solar system to generate? (1 kW = 1,000 Watts) Solar Panel Wattage (W) Most residential panels are 350–450W. Check your panel specs or use an average value. Solar Panel Area (m² per panel) Standard panels are about 1.6–2.0 m². Enter your panel's area or use an average.

How many watts is a solar panel?

Solar Panel Wattage (W) Most residential panels are 350–450W. Check your panel specs or use an average value. Solar Panel Area (m² per panel) Standard panels are about 1.6–2.0 m². Enter your panel's area or use an average. Panel Placement Loss Factor (%) Accounts for gaps, shading, tilt, and access. 5–15% is typical.

How many solar panels do I Need?

To calculate the number of solar panels you need, divide your system’s total capacity by the wattage of each panel. As the average home solar panel is about 400 W, an 8.5 kW system would consist of approximately 21.25 panels. Rounding up, a 22-panel installation may be best. Step 5: Estimate your required roof space for solar

How much space does a solar panel need?

The panel area depends on the required power output, sunlight availability and panel efficiency. On average, a 1 kW solar system needs about 100 sq. ft. of shadow-free space for optimal energy generation. Even a small shadow can reduce your solar panel’s efficiency by blocking sunlight and lowering energy output.
