Solar Panel Installers Hampshire

System-size pricing is useful, but most people think in terms of the house they actually live in. Here is what I typically quote across Hampshire, by home type, with VAT at 0% on domestic installations until 31 March 2027 (it rises to 5% from 1 April 2027). Every figure is a genuine range, not a teaser price — the exact number depends on your roof, scaffold access and consumption, which is why I survey every property personally before quoting.

Adding battery storage typically costs a further £2,500 – £5,000 depending on capacity — and a battery fitted with the panels (or retrofitted to an existing array) also qualifies for 0% VAT until 31 March 2027. See the full breakdown in my Hampshire solar cost guide.

Two honest caveats on the savings column. First, generation estimates assume a reasonably well-oriented, unshaded roof at typical south-coast yields — a north-facing or heavily shaded roof will produce less, and I will tell you so at survey rather than after installation. Second, your actual saving depends on how much generation you use in the home versus export: as of mid-2026, export tariffs vary widely between suppliers (roughly 12p–25p/kWh on common flat and fixed tariffs, and rates change at short notice), so always confirm the live rate with your supplier. My SEG rates guide is kept updated with the current picture.

The south-coast yield advantage

Well-oriented systems along the Solent corridor typically achieve around 950–1,050 kWh per kWp per year — comfortably above what the same panels would produce across most of the Midlands and the North. It is not a dramatic difference and I will never pretend Hampshire is the Mediterranean, but over a 25-year panel life those extra kilowatt-hours compound into a meaningfully shorter payback for the identical system. It is one of the quiet reasons solar stacks up well here.

Conservation areas and listed buildings

Hampshire is dense with conservation areas — Winchester district alone has 37 and Southampton has 20, and Winchester's historic core and Southampton's Old Town are the two I am asked about most. Roof-mounted solar usually remains permitted development in a conservation area: the specific extra restriction is that panels cannot be fitted to a wall fronting a highway, and every installation must be sited to minimise its effect on the building's appearance — that siting condition is what councils lean on when a prominent, highway-facing roof slope is involved, so it pays to get the layout right first time. Listed buildings always need listed building consent regardless of location. I check the planning position for your specific address as part of the survey, before you commit to anything. The detail is in my Hampshire planning permission guide and conservation area solar guide.

SSEN and the grid paperwork

Hampshire sits in the SSEN (Scottish and Southern Electricity Networks) southern licence area, and every grid-connected system needs either a G98 notification (systems up to 3.68 kW per phase, notified after connection) or G99 approval (larger systems, which need SSEN's sign-off before installation). G99 applications can add weeks if they are handled late or badly. I submit and manage all SSEN paperwork myself as standard — it is part of the job, not an extra, and it is one of the things that goes wrong most often when installation is subcontracted out.

Solar Together Hampshire

Hampshire County Council runs periodic rounds of Solar Together, a group-buying scheme where pre-vetted installers bid at auction to supply registered households; registration is free and typically opens in late summer with an auction in the autumn. It is a legitimate scheme and a useful benchmark. My honest advice: register if a round is open, then compare the group offer against a fixed quote from a local installer who has actually stood on your roof — group-buy pricing is based on a desktop assessment, and the installing company may be travelling from well outside the county. I am always happy to price against a Solar Together offer like-for-like.

I deliberately work with a small number of battery and inverter platforms rather than fitting whatever is cheapest that month. It means I know each system inside out — commissioning, app setup, firmware quirks and all — and you get one person accountable for the lot.

• SigEnergy — the SigenStor all-in-one tower: hybrid inverter, battery modules and energy management stacked in a single unit, modular from roughly 6 kWh to 54 kWh, with an optional DC EV-charging module. My pick where you want room to grow the system later.
• Fox ESS — one of the most widely installed hybrid inverter and battery brands in the UK. The modular EP-series units (roughly 5–11.5 kWh each, with up to four connected in parallel) make it a strong value choice for a typical 3-bed semi.
• GoodWe — a long-established inverter manufacturer whose Lynx Home battery ranges scale from around 5 kWh to 30+ kWh. Proven, well-supported kit that I trust on both simple and awkward installs.

How they compare head-to-head — capacities, warranties, backup capability and app quality — is covered in my best solar battery 2026 comparison.

One brand is deliberately absent. GivEnergy Ltd entered administration on 9 April 2026 and no new hardware warranties are being honoured by the company, so I no longer fit GivEnergy equipment — a warranty I cannot stand behind is not one I will sell you. If you already own a GivEnergy system: the app and monitoring portal continue to run under a separate company (GivEnergy Software Ltd), your panels and battery keep working, and I still service and maintain existing GivEnergy installations across Hampshire. I have written up exactly what the GivEnergy administration means for owners.

Do solar panels really generate more in Hampshire than the rest of the UK?

Can I fit solar panels in a conservation area like Winchester or Southampton's Old Town?

Should I add a battery at the same time as my panels, or later?
