From the waterfront terraces of Portsmouth to the rural lanes around Petersfield, Hampshire homeowners share one thing in common this year: energy bills that keep testing their patience. After the Ofgem price cap rose again in July 2026, more households across the county are looking to their own roofs for a way out.
Hampshire is genuinely well suited to solar, and 2026 is a strong year to make the move. This guide explains what a system costs, what you can expect to save, the local rules to be aware of, and how to choose an installer you can rely on. It comes from Cre8 Zero, an MCS-certified solar, battery and EV charging installer serving Hampshire and the wider South East.
Why Hampshire is well placed for solar
There is a stubborn myth that Britain is too grey for solar. It is not true, and it is especially not true on the South Coast. Solar panels run on daylight rather than heat, and they perform reliably across the year, including on bright but cool days.
Hampshire sits in the sunnier southern band of England, with the long coastline around Portsmouth, Southampton and the Solent enjoying some of the better daylight levels in the country. Inland towns like Winchester, Basingstoke and Andover do well too, and rural properties often have generous, unshaded roofs that suit larger systems.
Key takeaway: you do not need constant sunshine for solar to pay. Hampshire’s daylight, coastal and inland, is more than enough.
How much do solar panels cost in Hampshire in 2026?
Costs depend on your roof, the system size and whether you add a battery, so treat these as indicative ranges rather than fixed quotes.
- 3kW system (smaller home, 6 to 8 panels): roughly £5,000 to £6,500
- 4kW system (typical three or four-bedroom home): roughly £6,000 to £8,500
- 6kW system (larger home or higher usage): roughly £8,500 to £12,000
- Battery storage: typically an additional £3,000 to £6,000 or more
These reflect UK market prices in 2026 for supply and installation by an MCS-certified company. Larger rural homes near Winchester or Petersfield, with high usage and roof space, sometimes justify bigger systems where the cost per unit of capacity falls. A free survey is the only way to pin down your exact figure.
Make the most of the 0% VAT window
There is a worthwhile saving in place right now. Solar panels and battery storage installed on homes in Great Britain carry 0% VAT, and that relief is scheduled to run until 31 March 2027. After that, it is expected to rise to at least 5%.
Your installer applies the relief automatically on the invoice, with no forms to complete. On a typical Hampshire install that is worth hundreds of pounds, so 2026 is a sensible year to act while it lasts. Eligibility can vary by property type, which we confirm at survey, and a qualified adviser can help if your situation is unusual.
What could you save?
Your savings come from two places: using your own solar electricity instead of buying from the grid, and selling your surplus back through the Smart Export Guarantee.
A well-sited 4kW system in Hampshire can generate in the region of 3,400 to 4,000 units of electricity a year. As an indicative guide, many households save between £400 and £900 a year, and that figure grows as grid prices rise. With the price cap higher again from July 2026, every unit you generate and use yourself is worth more than it was.
Households at home during the day, or with a battery, tend to see the strongest returns because they use more of what they generate rather than exporting it cheaply.
Getting paid to export: the Smart Export Guarantee
The Smart Export Guarantee, or SEG, requires larger energy suppliers (those with 150,000 or more domestic customers) to pay you for the surplus electricity your system exports.
Worth knowing:
- Rates in 2026 vary widely, from around 1p per unit up to 30p or more per unit on the best battery-linked tariffs. Solid flat-rate options sit in the region of 12p to 16.5p per unit.
- Your export tariff is separate from your import supplier, so you can buy and sell with different companies.
- You need an MCS-certified installation and a smart meter to take part.
For a 4kW system without a battery, SEG income often lands in the region of £150 to £300 a year. Add a battery and a time-of-use tariff, and you can store power and export it when it pays the most.
Key takeaway: the SEG turns spare solar into income, but only with an MCS install and a smart meter.
Roof suitability and shading
Most Hampshire roofs are suitable for solar, with a few local points worth checking.
- Pitch and orientation: south, east and west-facing roofs all work well. A pitch of around 30 to 40 degrees is close to ideal, but panels perform across a wide range.
- Shading: in denser parts of Portsmouth and Southampton, neighbouring terraces, chimneys and mature trees can cast shade. Modern optimisers and microinverters limit the impact, so a partly shaded roof is rarely a dealbreaker.
- Coastal exposure: homes near the Solent benefit from open, unobstructed daylight, and quality mounting handles coastal conditions well.
- Roof condition: panels last for decades, so it is worth fitting them to a roof in good repair. We flag anything that needs attention at survey.
Should you add a battery?
A battery is optional, but for many Hampshire homes it strengthens the case. It stores solar generated during the day so you can use it in the evening, instead of buying expensive grid power at peak times.
Batteries also carry 0% VAT until 31 March 2027 and pair well with time-of-use export tariffs. For homes that sit empty during working hours, a battery can be the difference between using a small share of your solar and using most of it. We only recommend one where the numbers genuinely work for your usage.

Planning and permitted development in Hampshire
Most home solar installations across Hampshire fall under permitted development, so they do not need a planning application. There are sensible conditions on how far panels can project and where they sit.
You are more likely to need permission if your property is listed, sits within a conservation area, or falls inside the New Forest National Park or the South Downs National Park, both of which reach into Hampshire. Ground-mounted arrays can have different rules. None of this rules solar out, but it can shape where panels go. We check the position for your specific property and handle the relevant applications and notifications as part of our process.
Why a local, certified installer matters
Solar is a long-term investment, often lasting 25 years or more, so the company behind it matters as much as the panels. A local, MCS-certified installer can return quickly if your system ever needs attention, rather than a national outfit that has moved on.
MCS certification is not just a badge. It is required for both the Smart Export Guarantee and the 0% VAT relief, so choosing a certified installer protects your income and your saving. At Cre8 Zero, every installation is MCS-certified and carried out by fully qualified electricians, backed by an insurance-backed workmanship warranty and supported by our 5-star ratings on Trustpilot and Google.
We install across Hampshire, including Portsmouth, Southampton, Winchester, Basingstoke, Eastleigh, Petersfield, Fareham, Havant and Andover, as well as the surrounding towns and villages.
How to choose a solar installer in Hampshire
Before you commit, check that your installer:
- Is MCS-certified, required for the SEG and the 0% VAT relief
- Uses qualified, registered electricians
- Offers a product warranty and an insurance-backed workmanship warranty
- Provides a clear, itemised quote with no vague extras
- Can explain why they have designed your system the way they have
- Has genuine local reviews you can read for yourself
A trustworthy installer answers all of these happily. If a quote feels rushed or pressured, treat it as a reason to pause.
