About these figures:Sunshine hours and irradiance values are conservative regional averages derived from MCS PV yield data for south-facing systems at approximately 35° pitch. Actual site performance depends on roof orientation, pitch, shading, and panel technology. Figures are updated when MCS publishes revised data.
