How Many Solar Panels for 500 kWh per Month?
A home using 500 kWh per month may need roughly a 3.5-5 kW solar system in many climates. With common residential panels, that often means about 8-14 panels.
Global planning note: the same 500 kWh bill needs fewer panels in high-sun regions and more panels in cloudy or high-latitude regions.
What Changes the Estimate?
- Local peak sun hours and seasonal weather.
- Panel wattage and real-world system losses.
- Roof orientation, shade, and available mounting area.
- Whether you want partial or near-total bill offset.
Best Next Step
Use Panel Count to size the array, then compare the result with Savings.
Next step: turn 500 kWh/month into a practical panel count.
