Why solar makes sense here

Portsmouth has the sunniest solar conditions in Hampshire.

Portsmouth sits on the south coast and picks up more sunshine hours per year than most of England. Between the Victorian and Edwardian terraces on the island, the post-war semis around Cosham and Drayton, and the newer housing on the north side, most Portsmouth homes are worth quoting.

One of the sunniest parts of the country. Portsmouth averages around 1,700 hours of sunshine a year — up there with Eastbourne and the Isle of Wight. Every panel earns more here than the same panel in the Midlands.
Terrace stock dominates the island. Fratton, Copnor, North End, Baffins, Southsea — miles of solid Victorian and Edwardian terraces with south-facing rear roofs. Not the biggest arrays, but real returns and a shorter payback than most people expect.
Cosham, Drayton and Farlington go bigger. Larger detached and semi properties on the north side of the harbour often justify 5–7 kW systems, with a battery and EV charger from the start.
SSEN handles the grid paperwork. SSEN runs the local grid across Portsmouth, so Southern Electric handles any DNO admin. Your installer takes care of the G98 or G99 application — it’s not something you’ll ever need to chase up.

Worth knowing

A few Portsmouth-specific things to check

Most Portsmouth homes are straightforward for solar. But the island city’s density and coastal setting means a few property types need a bit more thought — worth flagging up front so a good installer can plan around them.

Old Portsmouth & conservation

Old Portsmouth, the Southsea seafront and parts of Fratton and Milton sit in conservation areas. Panels on the rear roof slope are generally OK under permitted development; anything visible from the street usually needs planning consent. Portsmouth City Council can confirm in a quick call — and any decent installer will flag it first.

Small terraced footprints

Portsmouth is one of the most densely built cities in the UK. Terraces in Fratton, Copnor, Southsea and North End have modest roofs — most end up with 3–4 kW systems rather than 5–6 kW. Still worth doing, but roof orientation matters more when space is tight.

Coastal / salt-air mounting

Homes within a mile of the sea — Southsea, Old Portsmouth, Eastney — need stainless steel or marine-grade aluminium brackets, not galvanised steel. The panels themselves are fine, but the fixings matter. Any decent Portsmouth-local installer already specs this — worth checking on your quote.

Harbour leasehold flats

Gunwharf Quays, Vulcan Way, the Lipstick and other harbour redevelopments are almost always leasehold with a freeholder-owned roof. Solar isn’t an individual leaseholder decision — it’d be a communal project through the management company. Worth raising at a residents’ meeting if you’re interested.

Portsmouth solar · FAQ

Things Portsmouth homeowners often ask

Do I need planning permission for solar panels in Portsmouth?

For most Portsmouth homes, no. Solar panels on a house are usually permitted development. The main exceptions are properties in conservation areas (Old Portsmouth, Southsea seafront, parts of Fratton and Milton), listed buildings, and panels sitting forward of the principal elevation. Portsmouth City Council can confirm if you’re unsure — and any good installer will flag it before quoting.

Can solar work on a Portsmouth terraced house?

Yes — and thousands already have it. Portsmouth is one of the most densely built cities in the UK, so terraced footprints are small. Most terraces here fit 3–4 kW systems (8 to 12 panels) rather than the 4–6 kW you’d see on a semi in Cosham or a detached in Farlington. When roof space is tight, orientation matters more — a south-facing rear slope is ideal. Any decent installer will assess this on a site survey.

Does the coastal / salt-air environment affect solar?

The panels themselves are fine — they’re rated for outdoor life and standard tempered glass handles marine environments well. What matters is the mounting hardware. For homes near the seafront in Southsea, Old Portsmouth or Eastney, use stainless steel or marine-grade aluminium brackets and fixings. Cheap galvanised steel corrodes fast within a mile of the sea. Any decent installer local to Portsmouth already specs this — worth checking on your quote.

What about harbour leasehold apartments (Gunwharf Quays, Vulcan Way)?

Same story as any leasehold flat: the freeholder or management company owns the roof, so solar isn’t an individual leaseholder decision. Some blocks have communal solar; most don’t. If you’re in Gunwharf Quays, Vulcan Way, the Lipstick or one of the harbour redevelopments, worth raising it at your next residents’ meeting. Not something we can quote for on an individual basis.

Which postcodes across Portsmouth do you cover?

We cover PO1, PO2, PO3, PO4, PO5 and PO6 in full — the whole island city plus Cosham, Drayton, Farlington and Portchester. We also cover PO7 (Waterlooville, Purbrook), PO8 (Horndean, Clanfield) and parts of PO9 (Havant). If you’re on the edge, fill in the form and we’ll come back to you.

Is it really free?

Yes. You never pay — the installers do, and only when we introduce them to someone genuine. No fee, no obligation, no upsell.
