How Many Solar Panels Do I Need for a 1,500 Sq Ft House?
For a typical 1,500 sq ft house, a planning range is often about 10-20 panels, but usage matters more than floor area. A smaller house with high electric demand can need more panels than a larger efficient home.
Short answer: many 1,500 sq ft homes land in the 5-8 kW range, or roughly 12-20 modern panels.
What Changes the Number?
- Monthly electricity use: the main driver of panel count.
- Panel wattage: higher-watt panels reduce total panel count.
- Roof layout: a smaller roof can limit the number of panels even if usage is high.
- Location: sun hours and temperature affect expected output.
