How Many Solar Panels for 1,500 kWh per Month?
A home using 1,500 kWh per month may need roughly a 10-15 kW solar system in a planning estimate. That often means about 24-38 panels with common residential panel wattages.
Short answer: 1,500 kWh/month is high enough that roof space, shade, and utility rules matter as much as the raw panel count.
What to Check First
- Roof fit: a larger system needs enough clear roof area with good sun exposure.
- Electric bill: monthly kWh is better than square footage for sizing.
- Battery needs: high-usage homes may need a separate backup plan.
- Utility policy: net metering, export rates, and time-of-use rates can change the best design.
Best Next Step
Start with Panel Count, then compare the estimate with Savings and Battery Sizing if you want backup.
Next step: estimate panel count, savings, and backup needs together.
