Quick answer

Hampshire homes sit in the SSEN distribution area, where South Coast Solar Solutions handles every G98/G99 grid connection. A typical 4–6kW system costs £5,000–£9,000, and the county's high Solent irradiance (~1,080 kWh/kWp) means strong year-round generation.

Hampshire is our home county. From our Portsmouth base we install solar panels, battery storage and EV chargers right across the county — from the dense terraced streets of Portsmouth and Southampton to the rural detached homes of the Meon Valley and the new-build estates around Whiteley and Waterlooville.

Every Hampshire property connects to the grid through SSEN (Scottish & Southern Electricity Networks), and we handle the full G98 (smaller systems) or G99 (battery and larger arrays) application on your behalf. Combined with some of the highest sunlight levels in the UK, that makes Hampshire one of the best places in the country to go solar.

What a 4kW system generates in Hampshire

~3,900–4,300 kWh

East-facing

~3,200–3,650 kWh

West-facing

~3,200–3,650 kWh

Grants & export income

Be honest about grants: most Hampshire homeowners won't qualify for one, and the main ongoing earner is the Smart Export Guarantee (SEG). SEG has been Ofgem-mandated since January 2020 (it replaced the old Feed-in Tariff export payment) — larger suppliers must offer an export tariff, and as of 2026 leading rates pay roughly 15p–27p per kWh, though each supplier sets and changes its own rate and you can hold your SEG tariff with a different supplier than your import one. Targeted schemes such as Solar Together group-buying, ECO4 and the Warm Homes local grants exist but are means-tested or property-specific, so they reach only a minority of households; we'll tell you plainly if you're likely to be eligible rather than promise savings that don't apply.

FAQ

Solar panels in Hampshire: FAQs

How much do solar panels cost in Hampshire?
A typical home system across Hampshire costs from around £5,500–£11,000 depending on size and battery storage, with 0% VAT on residential solar. ~1,080 kWh/kWp per year — a 4kW system typically generates 3,900–4,200 kWh annually. Every quote is tailored to your roof after a free survey.
Which electricity network (DNO) covers Hampshire?
SSEN (Scottish & Southern Electricity Networks). We handle the full G98 (smaller systems) or G99 (batteries and larger arrays) connection application on your behalf.
Do you need planning permission for solar panels in Hampshire?
Most installs are permitted development; conservation areas and listed buildings need sensitive design. The main planning authorities here include Portsmouth City Council, Southampton City Council, Winchester City Council, Fareham Borough Council. We advise per property and design discreet systems where required.
Which towns in Hampshire do you cover?
We install across Hampshire, including Romsey, Andover, Basingstoke, Fleet, Aldershot, Lymington, Emsworth, Portsmouth. If your town isn't listed, just ask — we very likely cover it.
Which grid operator (DNO) covers Hampshire, and do I need a G98 or G99 application?
Every Hampshire property connects through SSEN (Scottish & Southern Electricity Networks). Systems up to 3.68kW per phase usually use the simpler G98 'connect & notify' route, where SSEN is notified after commissioning. Larger systems, and anything with battery storage or export, need a G99 application submitted and approved before install. We file whichever applies on your behalf as standard.
Do I need planning permission for solar panels in Hampshire?
Usually not — domestic roof solar is normally Permitted Development provided panels sit no more than 200mm proud of the roof and not above the highest part of the roof (chimney aside). Exceptions include listed buildings (which need Listed Building Consent) and roofs fronting a highway in a conservation area — relevant in parts of Winchester and Portsmouth's older quarters. In those cases we design discreet all-black, rear-slope systems.
Is Hampshire sunny enough for solar to be worthwhile?
Yes — the Hampshire coast sees around 1,080 kWh/kWp a year, among the highest irradiance in the UK. A south-facing 4kW array typically generates roughly 3,900–4,300 kWh annually; east or west-facing roofs produce around 15–20% less but are still well worth installing here.
