Longitude = Latitude =
Module Azimuth= ° Module Tilt= °

Sun's Azimuth ° Zenith ° Elevation ° (using PSA formula) Airmass units (from Airmass formula) S_incident kW/m² (from Airmass Intensity formula) reduction in light intensity using equation above S_module kW/m² light intensity on the module

Equations Output:

Solar Intensity

$S_{m o d u l e} = S_{i n c i d e n t} [\cos (α) \sin (β) \cos (Ψ - Θ) + \sin (α) \cos (β)]$
