A typical south-facing roof in TR18 produces approximately 1,108 kWh per kWp of installed capacity each year. For a mid-sized commercial installation of 250 kWp, that translates to roughly 277 MWh of generation each year, enough to offset a significant portion of typical warehouse, logistics, or light-industrial electricity demand.
