How Many Solar Panels Do I Need for a 2,000 Sq Ft House?
For a typical 2,000 sq ft house, a planning range is often about 12-24 panels, but the real answer depends more on your monthly kWh, roof space, panel wattage, and local sun hours than on square footage alone.
Short answer: a 2,000 sq ft home often lands in the 6-10 kW range, which usually means roughly 15-25 modern panels depending on wattage and usage.
What Changes the Number?
- Monthly electricity use: the biggest driver. Higher kWh use means more panels.
- Panel wattage: 400W panels need more roof area than 550W or 700W panels.
- Roof space and shape: shade, vents, and setbacks reduce usable area.
- Location: sun hours and local weather affect the output each panel can produce.
