## Solar Panel Energy Estimation
Daily energy output depends on panel capacity, sunlight availability, and system losses.
### Formula
**Daily kWh = Array size (kW) x Peak sun hours x System efficiency**
Peak sun hours represent the equivalent hours of full-intensity (1000 W/m^2) sunlight per day, typically 3-6 hours depending on location and season. System efficiency accounts for inverter losses, wiring, temperature derating, dust, and shading.

Ejemplo Resuelto
10 panels of 400 W each, 5 peak sun hours, 80% system efficiency.
- Array size = 400 x 10 = 4000 W = 4.0 kWp
- Daily output = 4.0 x 5 x 0.80 = 16.0 kWh/day
- Annual output = 16.0 x 365 = 5,840 kWh/year
