Solar Irradiance Calculator — सूत्र
## Solar Irradiance and Energy Collection
Solar irradiance is the power of sunlight per unit area. Peak sun hours convert variable sunlight into an equivalent number of hours at 1,000 W/m².
### Formula
**Daily Energy (kWh/m²) = Peak Sun Hours x Orientation Factor**
**Total Daily Energy = Daily Energy x Panel Area**
Peak sun hours vary by location: 3-4 in northern climates, 5-6 in temperate zones, and 6-8 in sunny regions.

हल किया गया उदाहरण
A 20 m² array in a location with 5 peak sun hours and 90% orientation factor.
- Effective irradiance = 5 x 0.9 = 4.5 kWh/m²/day
- Daily energy = 4.5 x 20 = 90 kWh/day
- Annual energy = 90 x 365 = 32,850 kWh/year
