Solar Panel Installers in Hampshire

Every job starts with a survey, not a sales pitch. We look at your roof's orientation, pitch and any shading, then model your actual electricity usage against what the roof can produce. On the South Coast that means working from realistic local irradiance of roughly 1,050–1,150 kWh per kWp per year — a 4kW south-facing array in Hampshire typically generates around 3,900–4,600 kWh annually, with east/west roofs producing about 15–20% less. The survey is what turns a "from" price into a firm quote, and it's where we'll tell you honestly if solar doesn't stack up for your roof.

Next comes the grid paperwork, which in Hampshire means SSEN, the network operator covering the county. A small panel-only system at or under 3.68kW per phase goes through as a G98 connect-and-notify — we can install first and tell SSEN afterwards. Anything with a battery or meaningful export is a G99 application, which must be approved before installation. We file either one on your behalf; you never deal with SSEN directly. The G99 approval wait is usually the longest single step between survey and switch-on, which is why we submit it as soon as your design is fixed.

The install itself is typically one day. Scaffolding goes up, panels and bird mesh are fitted (mesh is included, not an extra), the inverter and any battery are wired in, and the system is commissioned and tested before we leave. Afterwards you receive your MCS certificate — the document that proves the installation was carried out by a certified installer to the required standard. You need it to register for a Smart Export Guarantee tariff, such as Octopus's Outgoing Fixed at 12p per kWh exported. We handle the handover pack so SEG sign-up is straightforward.

On coverage: we're based at the Victory Business Centre in Portsmouth, so the PO postcode corridor usually gets same-week surveys. Across the rest of Hampshire — Southampton and the SO postcodes, plus the GU and RG fringes in the north of the county — we run batched survey and install days, which keeps our travel efficient and your price down. Our service area is a hard boundary: Hampshire, the Isle of Wight, Dorset, Sussex and Surrey. We don't chase work beyond it.

On cost, honestly: a basic 8-panel system (DMEGC 450W panels with a Fox 3600 inverter) starts from £4,995. Adding battery storage starts from £6,995 with a Fox EP6 5.76kWh, while our standard packages start from £8,418 with Aiko 475W panels and EcoFlow storage. At the premium end, a 12-panel Tesla Powerwall 3 system starts from £12,920, with a £375 Tesla rebate currently available. All prices are "from" figures subject to survey — your roof, scaffolding access and chosen kit set the final number.
