Commercial solar in Southampton - FAQs

Is Southampton a good location for commercial solar?

Yes - Southampton receives around 1,000–1,080 kWh per kWp per year, among the highest UK commercial solar yields. Large port-side and M27 warehouse roofs typically pay back in 4–6 years on sites with daytime demand.

Do you cover Eastleigh, Fareham and the wider Solent?

Yes - Eastleigh, Fareham, Hedge End, Totton, Hamble, Romsey and the wider M27 / Solent commercial belt are all within our standard South East service area.

Are Port of Southampton warehouses suitable for solar?

Yes - most port-side and Nursling distribution buildings have large, unshaded modern roofs ideal for 250 kWp–2 MW arrays. Salt-air corrosion is factored into mounting and inverter selection at design stage.

How long does a Southampton commercial solar install take?

A typical 250–500 kWp Southampton warehouse install runs 4–8 weeks on site once permits and DNO approval are confirmed. Feasibility-to-energised lead time is normally 4–6 months.
