By matching roof area, tilt, and daily load, people can identify the optimum solar panel size without any guesswork. Understanding solar panel size per kW turns empty terraces into tidy power stations, while clear steps on how to size a solar panel system keep budgets slim and performance steady.
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
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.
