Solar Panel Installers in Portsmouth
Solar, battery storage and EV charging in Portsmouth — designed and installed by a local, MCS-certified team based in Portsmouth.
Quick answer
Portsmouth homes connect through SSEN, and as a PO1-based installer we handle every G98/G99 application. A typical 4kW system generates around 3,900–4,200 kWh a year here. We offer same-week surveys and design discreet systems for Southsea's conservation streets.
South Coast Solar Solutions is based in Portsmouth — Unit 218 at the Victory Business Centre on Somers Road North, PO1. That makes us a genuinely local installer for the city, with engineers who live here and same-week surveys across PO1–PO6.
Portsmouth's dense Victorian terraces, inter-war semis and seafront conservation areas each call for a different approach. We design around tight roof access, chimney and dormer shading, and the city's many east–west roofs using panel-level optimisation so every panel pulls its weight.
Solar in Portsmouth: the local detail
Grid connection (DNO)
Portsmouth is in the SSEN area. Most terraced installs up to 3.68kW per phase are notified under G98; battery systems and larger arrays go through G99, which we apply for before installation.
Local planning authority
Portsmouth City Council
Heritage & conservation
Old Portsmouth and the Southsea seafront sit within conservation areas, with Article 4 pockets near the front. We recommend all-black, low-profile panels and rear-slope siting where consent sensitivity applies.
Local housing stock
Dense Victorian and Edwardian terraces (Southsea, Fratton, North End), inter-war semis (Cosham, Drayton, Paulsgrove) and some 1960s flats. Roof-share scaffold access is the norm on terraced streets.
Typical roofs
Tight terraced roofs with frequent chimney and dormer shading; east–west splits are common. We use per-panel optimisers and split-MPPT inverters to handle them.
Sunlight & generation
~1,080 kWh/kWp per year; a 4kW south-facing array ≈ 3,900–4,200 kWh annually

Installing Solar Panels in Portsmouth From Inside Portsmouth
Our base is Unit 218, Victory Business Centre on Somers Road North, PO1 — which means Portsmouth is the one place we never have to plan a journey to. There is no travel padding in our quotes, surveys can usually happen the same week you call, and if anything ever needs looking at after installation, we are minutes away rather than a county away. When your installer's aftercare address is in the same postcode district as your roof, follow-up stops being a promise and becomes a short drive.
Portsmouth roofs have a character of their own, and we scaffold them every week. The Victorian and Edwardian terraces of Southsea, Fratton and North End typically run east-west, so many homes end up with panels split across two roof faces. That works well — an east-west array produces roughly 15-20% less than a perfect south-facing roof, but it spreads generation across morning and evening, which suits battery charging and home usage patterns. Because terraced roofs are tight and chimneys or dormers often throw shade across part of the array, we fit per-panel optimisers as standard where they are needed, so one shaded panel cannot drag down the whole string. The inter-war semis of Cosham, Drayton and Paulsgrove are usually more straightforward, with larger uninterrupted slopes.
Near the seafront, planning matters. Old Portsmouth and Southsea Common sit in conservation areas, and there are Article 4 pockets close to the front where permitted development rights are restricted. Our standard answer there is an all-black, low-profile system sited on the rear slope — discreet from the street and consistent with what Portsmouth City Council expects to see. We flag this at the survey stage, before any equipment is ordered.
Grid paperwork is ours to handle, not yours. Portsmouth is SSEN territory: a small system at or under 3.68kW per phase only needs a G98 notification, while battery and export systems go through G99 — and G99 approval has to be in place before the install, so we file it early as part of the job. With the paperwork sequenced properly, a typical Portsmouth installation is completed in a single day.

How much do solar panels cost for a typical Portsmouth terrace?+
A basic solar system starts from £4,995, solar plus battery from £6,995, and our standard package from £8,418. A premium Tesla Powerwall 3 system starts from £12,920 with a £375 rebate, and a battery-only Powerwall 3 retrofit from £7,450. All prices are 'from' and subject to survey — terraced roofs with splits or shading are exactly why we survey before quoting a final figure.
Do east-west terraced roofs in Southsea and Fratton actually work for solar?+
Yes. An east-west split produces roughly 15-20% less than an ideal south-facing roof, but with Portsmouth's solar resource of around 1,050-1,150 kWh per kWp per year, the numbers still stack up — and generation spread across morning and evening pairs well with a battery. Per-panel optimisers deal with chimney and dormer shading common on terraces.
Can I fit solar panels in a conservation area near the Portsmouth seafront?+
Usually, yes — with the right design. Old Portsmouth and Southsea Common are conservation areas, and some streets near the seafront sit in Article 4 pockets with restricted permitted development. We standardise on all-black, low-profile panels sited on the rear roof slope in these areas, and confirm the planning position at survey before anything is ordered.
How quickly can you survey my Portsmouth home?+
Portsmouth is our home city — the office is on Somers Road North, PO1 — so surveys can usually be arranged the same week you get in touch. There is no travel scheduling to work around, and installation itself typically takes one day.
