Solar Panel Installers in Southampton

Southampton isn't one roof type, and a quote that treats it that way is guesswork. Across SO14 to SO19 we see three broad patterns. The Victorian and Edwardian terraces around Portswood and Shirley typically have steeper pitched roofs split into smaller slopes, which often suits a compact 8-panel array such as our basic package from £4,995*. The interwar semis in Bitterne and Sholing usually offer a single clean slope with room for 10-12 panels, making them good candidates for a solar-plus-battery setup. And the waterfront apartments around Ocean Village? We'll be straight with you: flats usually can't have individual roof solar, because the roof belongs to the freeholder or management company rather than any one leaseholder. If that's you, we'd rather say so up front than book a survey that goes nowhere.

Orientation matters more here than most installers let on. Southampton sits between the Itchen and Test valleys, and plenty of streets run along those valley lines, so a lot of roofs face east-west rather than due south. That's not a dealbreaker — east/west arrays typically yield around 15-20% less than south-facing — but it changes the panel layout and the payback maths, and we design for it rather than pretending every roof points at the sun. On the South Coast's irradiance of roughly 1,050-1,150 kWh per kWp per year, a well-sited 4kW south-facing system generates around 3,900-4,600 kWh annually.

Southampton is SSEN's patch, and we handle the grid paperwork as standard. A small system at or under 3.68kW per phase goes through G98 — connect and notify, no waiting. Anything with a battery or export — which is most of what we install — needs G99 approval before the install, and we file that application for you so it's agreed with SSEN before a ladder touches your roof.

Two more Southampton-specific points. First, Southampton City Council participates in Solar Together Hampshire, the council-backed group-buying scheme. If you've registered, bring us the offer — we're happy to quote against it like-for-like so you can compare a group-scheme installer against a local one who'll be 19 miles up the M27 if anything ever needs attention. Second, that distance: we're based in Portsmouth, so reaching any Southampton postcode is a straightforward ferry-free run — no travel premium, no subcontractors, and the same team that surveys your roof does the install, typically in a single day.
