What solar panels cost in Hampshire
Hampshire sits in the southern price band, a little above the national average and well below London. There’s a busy installer market along the M3 and M27 corridors keeping quotes competitive. Typical 2026 installed prices, all with 0% VAT:
| System | Panels | Hampshire installed price | With 5kWh battery | With 10kWh battery | Typical home |
|---|---|---|---|---|---|
| 3kW | 7 | £4,700–£6,000 | £7,900–£9,600 | — | Terrace, small bungalow or starter home |
| 4kW | 9–10 | £6,000–£7,500 | £9,500–£11,400 | £11,000–£13,000 | 3-bed semi or bungalow, the Hampshire standard |
| 5–6kW | 12–14 | £7,000–£9,300 | £10,700–£13,000 | £12,200–£14,500 | 4-bed detached, EV, home in the day |
| 8kW | 18 | £9,600–£11,600 | — | £14,600–£17,000 | Large detached, farmhouse, heat pump |
Several things move a Hampshire quote. Clay tile and slate on period houses in Winchester, Alresford, Romsey and the villages adds £300–£900 (solar on slate). Three-storey townhouses in new-build estates need taller scaffolding. Listed or conservation-area homes may need all-black or in-roof panels. Rural properties with long cable runs or a ground mount cost more. A 1970s semi in Basingstoke or a coastal bungalow on Hayling Island is at the cheaper end. Solar Together Hampshire rounds usually come in below these ranges (see grants). National context: solar panel cost UK.
How much you’ll generate and save
PVGIS puts Winchester at about 1,287kWh of sunlight per m² a year, roughly 18% above the UK average. The coast from the New Forest to Hayling Island does slightly better, and north Hampshire slightly less. A well-oriented roof yields roughly 1,000–1,100kWh per kW of panels a year. For a 4kW system:
| 4kW system, roof facing… | Annual output | Saving/yr (no battery)* | Saving/yr (with battery)* | Payback (panels only) |
|---|---|---|---|---|
| South (±20°) | 4,100–4,500kWh | £780–£900 | £1,100–£1,300 | 7–9 yrs |
| South-east / south-west | 3,950–4,300kWh | £750–£860 | £1,060–£1,250 | 7–9 yrs |
| East or west | 3,300–3,500kWh | £630–£720 | £900–£1,080 | 8–10 yrs |
| East-west split (both slopes) | 3,500–3,800kWh | £670–£780 | £950–£1,150 | 8–10 yrs |
| North | 2,500–2,800kWh | £480–£580 | — | 12–14 yrs, usually not worth it |
*At ~25p/kWh import and 12p export, with about half the output used at home. Homes where someone is in during the day, or with an EV or heat pump, do better than the table. Solar panel output has the month-by-month curve, the calculator will run your own usage, and east-west roofs explains the split-array case.
Hampshire’s houses and roofs
Hampshire has about 776,000 households, including the two cities, and one of the widest ranges of housing in the South. By type:
- 1960s–80s estates. Basingstoke’s expansion estates, Andover, Havant, Waterlooville, Fareham and Eastleigh have simple concrete-tile roofs, side access and 8–12 panels. These are the easy, cheap Hampshire installs.
- New-builds. Hampshire builds more new homes than most counties, at Whiteley, Kings Barton in Winchester, Manydown in Basingstoke, Welborne near Fareham, Andover and around Chandler’s Ford and Hedge End. Many already have a few panels, often too few to matter, and adding more or a battery is a popular upgrade. Check the estate’s roof covenant and whether the existing inverter has room (adding a battery to existing panels).
- Coastal bungalows. Hayling Island, Lee-on-the-Solent, Stubbington, Milford-on-Sea, Barton-on-Sea and New Milton have large low roofs, single-storey scaffolding and owners often home in the day. They’re ideal, with a note on salt and wind in the installation section. See solar for the over-65s.
- Commuter detached houses. Fleet, Hook, Hartley Wintney, Chandler’s Ford, Romsey and Winchester’s outskirts have big multi-slope roofs, high usage and EVs. They’re the natural home for 6–10kW systems and batteries.
- Victorian and military towns. Aldershot, Farnborough, Gosport and parts of Winchester have slate terraces and villas. They work if the right slope gets the sun, and chimneys may call for optimisers. See the 3-bed house guide.
- Period cottages and thatch. New Forest villages, the Test and Itchen valleys and East Hampshire have plenty of thatch. Panels can’t go on thatch, but they can go on an outbuilding, a garage or the ground (ground-mounted solar, solar on a garage, unusual roofs).
Many Hampshire villages are off the mains gas grid and heat with oil or LPG. For those homes, solar with a heat pump and the £7,500 Boiler Upgrade Scheme grant is the strongest combination going, and a solar immersion diverter cuts summer oil use.
Basingstoke semi, New Forest cottage or a Fleet detached?
A vetted Hampshire installer surveys your roof with a shade analysis, checks the tiles, access and any planning designations, and gives you a real output figure. It’s free, with no obligation, and you’ll get a straight answer if solar isn’t right for your home.
Check My Roof Free →Solar panel installation in Hampshire: thatch, coast and countryside
A typical Hampshire installation takes one to two days once scaffolding is up. Three local situations change the job. Thatched homes: panels never go on thatch, which also raises the fire-safety bar for cabling. A detached outbuilding or a ground mount, with cables run underground, is the standard answer. The coast: homes along the Solent and on Hayling Island get salt spray. Insist on stainless-steel fixings and panels certified to the salt-mist standard (IEC 61701), and exposed sites need the mounting designed to the local wind zone. Rural properties: long drives, soft ground for scaffolding and outbuilding arrays add time, and a farmhouse on a three-phase supply can take a bigger system. See how long installation takes and how panels are installed.
Planning: New Forest, South Downs and conservation areas
Most Hampshire houses can have roof panels under permitted development with no application, provided the panels sit no more than 200mm proud of the roof, don’t rise above the ridge, are sited to minimise their visual impact and the building isn’t listed. Hampshire has more designations than most counties:
- New Forest National Park. The National Park Authority is the planning authority. Its guidance confirms roof panels are generally permitted development there too. It also states that planning permission is needed for panels on any building within the curtilage of a listed building, which matters in New Forest villages where outbuildings are the obvious spot.
- South Downs National Park. This covers much of East Hampshire, around Petersfield and the Meon Valley, and the South Downs National Park Authority sets planning policy. Roof panels on ordinary houses remain permitted development. Ground-mounted systems face stricter rules in both national parks.
- National Landscapes. The North Wessex Downs in the north-west and Chichester Harbour around Emsworth and Hayling don’t affect roof panels on houses, but they do affect ground mounts.
- Conservation areas. There are many across the districts, including Winchester, Romsey, Alresford, Lymington, Stockbridge, Odiham, Petersfield and Emsworth. Roof panels are still permitted development, even on a front slope. What needs consent is panels on a wall, balcony or roof enclosure facing a highway, or anywhere an Article 4 direction has removed those rights, so check with your district. See solar in conservation areas.
- Listed buildings. Listed building consent is always needed. Rear-slope and outbuilding installs are approved more often than people expect (solar on listed buildings).
Hampshire has 11 district and borough councils plus Portsmouth and Southampton, each with its own planning service, and the two national park authorities on top.
Grants and the Hampshire County Council solar scheme
- Solar Together Hampshire. This is the “Hampshire County Council solar panel scheme” people search for. The county council runs it with the district councils as a free, no-obligation group-buying scheme: vetted installers bid in a reverse auction and registered households get a personalised offer for panels and batteries. Rounds usually open once a year. Registration is closed at the moment, so watch your district council’s website for the next round. The trade-offs are that installs come in batches and you don’t pick the installer, but it’s a useful benchmark even if you go elsewhere.
- Warm Homes: Local Grant. Hampshire’s district councils deliver this with Warmer Homes. It can fully fund insulation, a heat pump and, where the roof suits, solar panels for owner-occupiers and private tenants in homes rated EPC D–G, with a household income of £36,000 or less or a means-tested benefit. Availability varies by district. New Forest District Council, for example, has stopped taking applications because it’s oversubscribed, and residents can register interest instead. Apply early wherever you are.
- ECO4. All ECO4 work nationally must be finished by 31 December 2026, so a new application now is a race against the clock.
- Everyone else. 0% VAT runs until 31 March 2027 (then 5%), plus Smart Export Guarantee payments. There’s no free-panel scheme for most Hampshire homeowners, and cold callers offering one are a red flag (solar panel scams).
Full detail: solar grants UK, free solar panels, who actually qualifies, ECO4 and how to finance solar.
The DNO: SSEN
Hampshire’s local network is run by Scottish and Southern Electricity Networks (SSEN) through its Southern Electric Power Distribution licence area. Systems with an inverter up to 3.68kW per phase connect under a G98 notification after installation. Larger systems, including most battery installs, need a G99 application before connection. SSEN runs a G99 fast-track for typical home solar and battery systems and aims to respond within 10 working days. Approval sometimes comes with an export limit, often 3.68kW, which caps what you sell, not what you use. Your installer handles the paperwork. Once connected, register for export payments with any SEG supplier (SEG tariffs compared).
Is a battery worth it in Hampshire?
A 4kW south-facing Hampshire roof can export 2,000kWh-plus a year without storage, so a battery has plenty to work with. A 5–10kWh unit at £3,500–£5,500 lifts self-consumption from around 50% to 75–85% and adds £320–£450 a year. Charging from a cheap off-peak tariff in winter adds more (off-peak charging, Intelligent Octopus Go). An export limit strengthens the case further. It’s worth it if you’re out in the day, have an EV or want backup in rural areas prone to power cuts, and optional if someone’s home during daylight. Payback on the battery alone is 9–12 years. See are solar batteries worth it, what size battery, battery backup in power cuts and the batteries hub. Tesla doesn’t sell solar panels in the UK, but the Powerwall 3 is fitted by certified Hampshire installers.
Commercial, farm and school solar in Hampshire
Hampshire has a strong case for commercial solar. Business parks and logistics along the M3 and M27 corridors, at Basingstoke, Farnborough, Eastleigh, Andover and Fareham, have large roofs and daytime loads. Farms and estates in the Test Valley, North Hampshire and the New Forest fringe have barns that take 50–250kW. Schools and community buildings use most of their power in daylight. With the 100% Annual Investment Allowance, the business-rates exemption on onsite renewables to 2035 and installed costs of £450–£1,000 per kW at scale, payback is typically four to seven years. SSEN’s G99 process for larger systems takes longer, so start early. See commercial solar panels, solar for farms and solar for schools.
Maintenance, servicing, cleaning and repairs in Hampshire
With over 52,000 systems, Hampshire has a big aftercare market. Maintenance and servicing: panels need little, but a check every few years on the inverter, isolators, fixings and monitoring is sensible, especially on systems over ten years old. Expect £100–£200 for a service (maintenance, servicing). Cleaning: rain does most of the work on pitched roofs. Coastal homes along the Solent and rural homes near farmland benefit from a gentle clean every one to two years. It costs £80–£200 with deionised water and soft brushes, never a pressure washer (do solar panels need cleaning). Pigeons and gulls: bird mesh costs £300–£900 and is far cheaper fitted at install (bird-proofing). Repairs: many early-2010s Hampshire systems now need a new inverter, which costs £800–£1,500 (inverter replacement, solar panels not working, repairs).

Solar panel installers in Hampshire: how to choose
Hampshire has one of the busiest installer markets in the South. There are established independent MCS firms around Southampton, Portsmouth, Winchester and Basingstoke, the Solar Together installers, and the national brands. A good local installer will usually beat a national by £1,000–£2,000 on the same specification. They’ll also know SSEN’s habits and the national park planning teams, and will have handled thatch, coastal and new-build jobs before. Whoever you consider, run the same checks:
- They’re on the MCS register under their exact trading name.
- They’re a member of HIES or RECC.
- They’ve been trading for three years or more at Companies House.
- The panel, inverter and battery are named in writing.
- The quote includes a shade analysis.
- They’ve checked your planning designations.
- You get a ten-year insurance-backed workmanship guarantee.
- There’s no “today only” pricing.
After Effective Home’s collapse in June 2026, pay any deposit by credit card. How to choose a solar installer is the full checklist, and solar panel companies UK compares the nationals.
The bottom line on solar panels in Hampshire
Hampshire is one of the better counties in England for solar. £6,000–£7,500 buys a 4kW system that generates 4,100–4,500kWh a year on a south-facing roof, saves £780–£900 and pays back in seven to nine years, and more than 52,000 Hampshire homes have already done it. Estate semis, new-builds and coastal bungalows are the easy wins. Thatch, listed buildings and national park outbuildings need a specialist who knows the rules.
If you’re on a lower income in a D–G rated home, check your district’s Warm Homes: Local Grant. If you’re not, watch for the next Solar Together Hampshire round as a benchmark, remember the 0% VAT window closes on 31 March 2027, and get a vetted local quote to compare.

Solar panels in Hampshire: frequently asked questions
How much do solar panels cost in Hampshire?
A typical 4kW system of 9–10 panels costs £6,000–£7,500 installed in Hampshire in 2026 with 0% VAT, a little above the national average. Add £3,500–£5,500 for a 5–10kWh battery, so a 4kW system with a battery is £9,500–£13,000. Clay-tile and slate period roofs, three-storey townhouses, listed or conservation-area homes and rural ground mounts cost more. An estate semi in Basingstoke or a coastal bungalow is at the cheaper end, and Solar Together Hampshire rounds usually come in below open-market prices.
Are solar panels worth it in Hampshire?
Yes. PVGIS puts Winchester about 18% above the UK average for sunlight, and a well-oriented roof in Hampshire yields around 1,000–1,100kWh per kW of panels a year. A 4kW south-facing system generates roughly 4,100–4,500kWh, saves £780–£900 a year at 2026 prices and pays back in seven to nine years on a 25-year asset. That’s why more than 52,000 Hampshire homes, 6.7% of households, already have solar, above the 5.6% national average.
Does Hampshire County Council have a solar panel scheme?
Yes. Solar Together Hampshire is a free, no-obligation group-buying scheme run by Hampshire County Council with the district councils, in which vetted installers bid to supply panels and batteries to registered households. Rounds usually open once a year and registration is currently closed. Separately, lower-income households in homes rated EPC D–G can apply to their district council for the Warm Homes: Local Grant, delivered with Warmer Homes, which can fully fund solar panels, though some districts such as New Forest are oversubscribed.
Do I need planning permission for solar panels in Hampshire?
Usually not. Roof-mounted panels are permitted development on most Hampshire houses, including in the New Forest and South Downs national parks and in conservation areas, provided they sit no more than 200mm proud of the roof, don’t rise above the ridge and the building isn’t listed. Listed buildings need listed building consent. In the New Forest, panels on a building within the curtilage of a listed building need planning permission, and wall-mounted panels facing a highway in a conservation area need consent. Thatched roofs can’t take panels.
Who is the DNO for solar panels in Hampshire?
Scottish and Southern Electricity Networks (SSEN), through its Southern Electric Power Distribution network, covers Hampshire including Portsmouth and Southampton. Systems up to 3.68kW per phase connect under a G98 notification after installation. Larger systems and most battery installs need a G99 application first, and SSEN’s fast-track process for typical home systems aims to respond within 10 working days. Some approvals come with an export limit, often 3.68kW.
Do solar panels in Hampshire need maintenance or servicing?
Very little. Rain keeps most pitched-roof panels clean, but a check every few years on the inverter, isolators, fixings and monitoring is sensible, especially for systems over ten years old, and costs around £100–£200. Coastal homes along the Solent and rural homes near farmland benefit from a gentle clean every one to two years for £80–£200. Many early-2010s systems now need a replacement inverter, which costs £800–£1,500.
Figures are typical 2026 estimates for Hampshire for guidance only. Installed prices vary with roof type, access, system specification and installer. Yields are indicative ranges from PVGIS-type modelling and depend on orientation, pitch and shading. Savings assume ~25p/kWh import and ~12p export and change with tariffs. Installation and household figures are approximate, based on MCS data for January 2026. Warm Homes: Local Grant availability varies by district and changes, and Solar Together Hampshire round dates are set by the councils. National park planning guidance is summarised from the New Forest National Park Authority and the General Permitted Development Order as amended in 2026. Network connection rules are as published by SSEN. 0% VAT on residential solar and batteries applies until 31 March 2027 per HMRC. Always obtain quotes from MCS-certified installers and check the generation method used.
