Peak Sun Hours

The equivalent number of hours per day when the sun delivers 1,000 W/m². Used to estimate solar production: system size (kW) × peak sun hours × days ≈ daily kWh. Varies by location and season.

Example

A city with 5 peak sun hours and a 6 kW system might produce about 30 kWh on a clear day.
