Home Solar Panel Count Calculator
Enter daily energy demand, panel watt rating, and average sun hours to estimate how many panels are required.
CalcSimpler Examples
- 30 kWh/day with 300 W panels and 5 sun hours ⇒ 20 panels
- 15 kWh/day with 350 W panels and 4 sun hours ⇒ 10.71 panels
FAQ
Should I round up the result?
Yes, round up to ensure sufficient capacity.
Does this include battery storage?
No, it only estimates panel count.
What if sun hours vary?
Use an annual average or recalculate for different seasons.
Additional Information
- Assumes panels operate at their rated wattage during peak sun hours.
- Real-world performance depends on orientation, shading, and temperature.
