If you live in the hilly county of Hampshire and want to lower your electricity bills, solar panels are the best way to do it.

From Basingstoke to the New Forest, Hampshire enjoys more sunlight than most places in the UK, which gives it a distinct advantage over other counties when it comes to going solar.

In this guide, we’ll go through how much solar panels cost in Hampshire, how well they work in this weather, and which government grants can help you lower the cost.

At Sunsave we install across the whole of Hampshire – so if you’re wondering how much you could save with a solar & battery system, enter a few details below and we’ll provide an estimate.

What are the best solar panel installers in Hampshire?

1. Sunsave

At Sunsave, our mission is to make solar accessible to all UK households, which is why we’re offering the UK’s first solar subscription service. We install across England, Scotland, and Wales – including Hampshire.

Sunsave Plus allows you to start saving on your energy bills immediately, without having to pay anything upfront.

You’ll get the best-in-class kit installed on your roof, access to the best export tariffs, and the 20-year Sunsave Guarantee, which includes 24/7 monitoring, maintenance, a free battery upgrade, an inverter replacement if necessary, and downtime cover – all for a fixed monthly fee.

Your system will also be insured by Aviva against damage, fire, and theft.

2. JEM Energy

JEM Energy has been serving the people of Hampshire since 2015, which is long enough to develop a reputation.

Fortunately, James Rodwell and Alex Payne's company enjoys an excellent relationship with its customers, who have given the firm an excellent rating on Google and a near-perfect set of reviews on Checkatrade.

This is largely down to the team's expertise, excellent communication, and detailed designs, which makes sense considering Rodwell has more than a decade of experience in the renewable industry.

JEM Energy also installs heat pumps, if you want to make the most of your new solar panels.

3. Volt Energy Southern

This Waterlooville-based company is one of the only installers in Hampshire to be approved by the MCS, NAPIT, TrustMark, and HIES or RECC – and that's no mean feat.

Founded in 2022, the business is co-owned by locals Gus Stephens, Robert Pittman, and Mason Ling.

Pittman has led teams in the renewable energy sphere for five years, while Stevens has spent seven years working in the sector, so they know what they're doing.

The company has also embedded itself in the community, having sponsored local football team AFC Portchester Ladies and events at children's wards in Queen Alexandra Hospital Portsmouth.

4. Ecovolt Renewables

This family-run business is owned by Katherine and Michael Beckett.

Michael spent decades fixing yachts all over the world before deciding to settle down in Petersfield and open a renewable installation company in 2022.

The qualified electrician engages with the community at events organised by groups like the Petersfield Climate Action Network.

The company's site explains that Michael "takes great pleasure in the process of designing and installing impeccable energy solutions."

How much do solar panels cost in Hampshire?

A 4.5kWp solar panel system costs £7,784 to buy and install in Hampshire, on average, according to MCS data.

For this price, you should be able to get 10 solar panels, each one with a 450-watt peak power rating.

We've also included the cost of adding a 5kWh battery, because a battery can significantly boost your solar returns.

It empowers you to use more solar-generated electricity at home – known as self-consumption – which means you can buy less electricity from the grid.

You can also join the best export tariffs and time-of-use import tariffs, and join grid flexibility services like virtual power plants.

Around 94% of new solar panel installations in the UK include a battery, according to data from Flexi-Orb and the EPVS.

Multiple factors may cause your specific solar panel system’s price to be different though, including its size, the installation’s complexity, and the installer you choose.

Are there any grants for solar panels in Hampshire?

There are solar panel grants available to Hampshire residents, mainly thanks to national government schemes, but they usually have strict eligibility criteria that targets the most underprivileged homes.

If you don’t qualify for any of these programmes and you're put off by the price of going solar, have a look at Sunsave Plus, which is available at no upfront cost.

For fixed monthly payments over 20 years, you’ll receive the best-in-class kit, full monitoring and maintenance support, and a system that can save you money from day one.

Solar Together Hampshire

Solar Together helps residents and business owners in a specific area to secure a discount on their solar installations through collective buying.

It’s not a government grant; it's a profit-making scheme run by private Dutch company iChoosr, in collaboration with local councils.

In London, it secured 20-30% discounts for its customers, according to the Greater London Authority.

And some places have seen even larger price reductions. In Suffolk, households have reportedly saved an average of £2,000 on installation costs.

Solar Together first came to Hampshire in 2021, and its first three schemes in the county led to around 2,700 households switching to solar.

The initiative passes through the county roughly once per year, for a limited time.

Unfortunately, it comes with significant downsides. To learn more, read our comprehensive guide to Solar Together.

National grants

There are a couple of national grants that apply to residents in Hampshire – and if you’re eligible, they’re well worth considering.

Solar panels can cut your energy bills by hundreds of pounds per year, shrink your carbon footprint, and increase your property’s value, but the upfront cost is usually high.

Warm Homes: Local Grant

The Warm Homes: Local Grant (WH:LG) is a government initiative that funds measures which improve the energy efficiency and heating systems of energy-inefficient homes in England.

Qualifying households must be low-income, deprived, or receive a means-tested benefit.

In 2025, the scheme awarded just over £26 million to a consortium including every local authority in Hampshire, as well as more than a dozen in West Sussex, Berkshire, and further afield.

All these local authorities can allocate up to £30,000 in funding to qualifying homes – £15,000 for energy performance upgrades like solar panels, and £15,000 for low-carbon heating.

If you live in one of these areas and the council decides your household could meet the grant's eligibility criteria, a staff member will contact you.

Energy Company Obligation (ECO4)

The government’s main initiative for cutting domestic emissions is available to low-income and vulnerable households whose residents are on certain benefits – though the scheme ends in March 2026.

ECO4 isn’t a government grant; it instead forces large energy suppliers to install energy-saving measures in underprivileged households.

You may be able to get a free solar panel system through ECO4, but only if your home is electrically heated, like 11.2% of households in England.

How many homes in Hampshire have solar panels?

52,009 homes in Hampshire have solar panels certified by the Microgeneration Certification Scheme (MCS), as of January 2026.

That means 6.7% of 776,000 households have gone solar, across the county's 13 local authorities.

This is considerably higher than the 5.6% of all UK households that have bought solar panels – which makes sense, since Hampshire is one of the sunniest places in the country.

Is it worth getting solar panels in Hampshire?

It’s absolutely worth getting solar panels in Hampshire, even more so than it is in most places in the UK – as 6.7% of households in the county have discovered.

If you’re put off by the upfront cost, you could look into accessing a national or local grant.

However, if you can't qualify for any of these, consider Sunsave Plus, our all-in-one solar and battery solution that’s tailored to your home, and delivered as a monthly subscription with no upfront cost.
