Commercial & Industrial Solar in Stevenage (SG1)

Solar potential in Stevenage (SG1)

A typical south-facing roof in SG1 produces approximately 1,025 kWh per kWp of installed capacity each year. For a mid-sized commercial installation of 250 kWp, that translates to roughly 256 MWh of generation each year, enough to offset a significant portion of typical warehouse, logistics, or light-industrial electricity demand.

Actual yield varies with roof orientation, pitch, shading, and inverter efficiency. The figure above represents clear-sky, unshaded south-facing potential.
