Solar potential in Plymouth (PL4)
A typical south-facing roof in PL4 produces approximately 1,060 kWh per kWp of installed capacity each year. For a mid-sized commercial installation of 250 kWp, that translates to roughly 265 MWh of generation each year, enough to offset a significant portion of typical warehouse, logistics, or light-industrial electricity demand.
