Renewable Energy

Basic

Solar Power on a Surface

Sunlight power hitting a tilted surface.

Formula

P = G \times A \times \cos\theta

Variables

PPower (W)

GIrradiance (W/m²)

AArea (m²)

θAngle from normal

Example

G=1000, A=2, θ=30°: P ≈ 1732 W

Did You Know?

Peak sunlight delivers about 1000 W/m² — the '1 sun' benchmark used to rate panels.
