Solar potential in Windsor (SL4)
A typical south-facing roof in SL4 produces approximately 1,022 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.
