The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
SolarTech’s regional production data helps hit that sweet spot for maximum value and performance. Each solar panel requires approximately 17-20 square feet of roof space, including necessary spacing for installation and maintenance. A typical 20-panel system needs 340-400 square feet of unshaded roof area.
A typical 20-panel system needs 340-400 square feet of unshaded roof area. Orientation: South-facing roofs provide maximum energy production Tilt: 30-45 degree angles optimize solar collection Shading: Minimal obstruction from trees, chimneys, or neighboring buildings Age: Roofs should have 10+ years of remaining life before panel installation
A1 SolarStore calculator has already proposed 32 panels 325 W each for the 10.24 kW medium size solar PV system. The formula is very simple: There is one variable in the formula above – solar panel output. It means that you can design a system consisting of 26 panels 390 W each, for example.
