How is Solar Output Calculated?
The energy produced by a photovoltaic (PV) system depends on the sun intensity and system losses.
Basic Formula:
Daily kWh = (System Size kW) × (Sun Hours) × (Efficiency)Key Factors:
- Peak Sun Hours: Not the total daylight length, but the equivalent hours of full sun (1000 W/m²).
- Efficiency: Real-world factors like heat, dust, wiring, and inverter conversion usually result in 15-20% loss.
