If you’re fortunate enough to live near Surrey's crystal grotto, historic castles, and gorgeous landscapes (particularly from Box Hill), and you’re looking to cut your electricity bills, solar panels could be the best choice.

From Dippenhall to Limpsfield Chart, Surrey receives more sunlight than most parts of the UK, which gives solar households a huge advantage.

In this guide, we’ll go through how much solar panels cost in Surrey, how the county’s weather could affect your savings, and which grants could help you cut the upfront cost.

We install across Surrey, 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 installers in Surrey?

We’ve created a set of rigorous tests to assess more than 4,700 solar installers across the UK, and these firms have performed the best of any that install in Surrey – even if none of them are headquartered there.

Every one of these five installers has been certified by the Microgeneration Certification Scheme (MCS) or Flexi-Orb, accredited by HIES or RECC, approved by TrustMark, registered with NAPIT or NICEIC, and earned a top rating across one or two reputable review sites.

The very best installers are also Which? Trusted Traders and offer a solar subscription option, though Sunsave is the only top-tier firm that fulfils both of these criteria and installs in Surrey.

To see the top companies in the UK, check out our national guide to the best solar panel installers.

1. Sunsave

Our mission is to make solar accessible to all UK households, which is why we provide the UK’s first solar subscription.

Sunsave Plus allows you to start cutting your energy bills from the get-go, with no upfront cost.

You’ll receive best-in-class kit, access to the best export tariffs, and the 20-year Sunsave Guarantee. This includes 24/7 monitoring, maintenance, a free battery upgrade and 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.

Our customers are massive fans of our work – and to prove it, they’ve given us more than 350 five-star ratings on Trustpilot, while highlighting our helpful, knowledgeable approach.

2. Infinity Energy Services

Not many solar installers who started up during the Feed-in-Tariff-fuelled solar boom of the early 2010s stuck around – but Infinity Energy Services has thrived.

The company has expanded beyond its Hampshire base, and now covers more or less all of south England, bar Cornwall and Kent – including Surrey.

Founder Daniel Hanslip has grown his team to an impressive 37 staff members, who have now completed thousands of installations."Meet the Team", Infinity Energy Services, accessed September 2026

His company has kept its personal touch, though. Every customer is promised one point of contact for their project, and receives a five-year workmanship warranty – and it seems to have worked.

Hanslip and his team took home Regional Solar PV Installer of the Year at the South East Energy Efficiency Awards in 2023, then won it again in 2024 and 2026.

3. South East Solar and Electrical

Since Oliver Lloyd launched South East Solar and Electrical in 2014, the firm has steadily grown into a success story.

The company's branded vans can be seen travelling all over south-east England while regularly carrying out 20 to 40 solar installations per week – to which they attach five-year workmanship warranties.

And in June 2026, the company announced: "What started as a small business has grown into a dedicated team of 19 office staff, 11 electricians, 10 solar panel installers, and two surveyors".

These 42 staff members have also helped the business expand into commercial activities, including helping local churches and farms to switch to solar.

Lloyd also runs a scaffolding company and indoor golf simulator, and featured on Channel 5's documentary, Solar Panels – Are They Really Worth It?.

4. Sussex Solar

The oldest company on this list started out in the halcyon days of 2005, back when solar panels were an oddity rather than a massive, money-saving industry.

It was founded by Andy Baxter, who's put his Mechanical Engineering degree to good use while overseeing more than 700 solar, battery, and heat pump installations in Surrey, Hampshire, Kent, and – of course – Sussex.

He still runs the firm with the help of 11 staff members, including his wife Amanda and son Dominic, and has attained Which? Trusted Trader status.

Sussex Solar has also achieved a measure of fame, through its appearances on BBC Two's Working Lunch programme in the 2000s.

Disappointingly though, the company only offers a standard two-year workmanship warranty.

5. Jelvis Electrical

In 2011, Grant Jelley and Elliot Davis combined their surnames to form this company, and it's paid off handsomely.

Jelvis Electrical has now finished more than 6,000 residential, commercial, and industrial projects, according to the firm.

From its base in Chichester, the team installs solar & battery systems all over West Sussex and the surrounding areas – including Surrey – and maintains a perfect rating on Checkatrade.

This is an impressive achievement, which the company puts down to its focus on "quality workmanship, energy efficiency, and long-term value – with every job delivered to the highest standards."

How much do solar panels cost in Surrey?

A 4.95kWp solar & battery system costs £12,740 to buy and install in Surrey, on average.

This system includes 11 solar panels, which each have a 450-watt peak power rating.

We've factored in the approximate cost of installing a 10kWh solar battery, because it can substantially boost your returns.

A battery enables you to use more solar electricity at home – known as self-consumption – which allows you to buy less electricity from the grid.

You can also earn money by using one of the best export tariffs and time-of-use import tariffs, and by joining any of the increasingly profitable virtual power plants sweeping the nation.

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

There are multiple reasons why you may end up paying a different amount for your solar panel system, such as its size, the job’s complexity, and which installer you choose.

Are there any grants for solar panels in Surrey?

There are no locally funded grants for solar panels offered in Surrey.

However, residents can still access the same government grants available to households across the UK.

If you qualify, you may be able to get free solar panels through the Energy Company Obligation (ECO4) scheme or Warm Homes: Local Grant.

Surrey County Council offers plenty of resources to anyone looking to cut their energy bills – including an impressively thorough home energy improvement guide – but most of its climate funding seems to be understandably targeted at preventing flooding.

Solar Together Surrey

Surrey residents can sometimes register for Solar Together, a programme that allows homeowners and small businesses to secure a discounted solar installation through the power of collective buying.

It's not a government grant though; it's a scheme created by private Dutch company iChoosr, which operates in conjunction with local authorities in England.

In London, it achieved 20-30% discounts for households, according to the Greater London Authority.

The scheme has come to Surrey four times since 2021, and has helped thousands of households to go solar.

Solar Together only appears in a few counties each year, and every project is time-limited, so you’ll have to wait and see if it comes back to Surrey – though it seems likely.

Unfortunately, the initiative comes with some substantial downsides, so it's worth doing your research before registering. To learn more, read our comprehensive guide to Solar Together.

National grants

There are a couple of national grants that Surrey households can apply for – and if you think you could qualify, it's worth taking a closer look.

Solar panels can cut your electricity bills by hundreds of pounds every year, lower your emissions, and increase your property’s value, but the upfront cost tends to be high. Grants can reduce or eliminate this fee entirely.

To find out which schemes you could qualify for, use our grant eligibility checker.

Energy Company Obligation (ECO4)

ECO4 is the government’s primary initiative for cutting residential emissions – and if you live in a low-income or vulnerable household with a resident who receives a qualifying benefit, you may be able to secure some home improvements.

Unfortunately, the scheme is set to end in December 2026.

Until that point, the government will continue to compel large energy suppliers to make energy-efficient upgrades in deprived homes across the country, at no cost to inhabitants.

ECO4 can get you a free solar panel system, as it has done for more than 66,000 households – but only if your home is heated with electricity, as 11.2% of households in England are.

To find out more, read our full guide to the ECO4 scheme.

Warm Homes: Local Grant

This government programme hands out funding to local authorities in England that they can use to upgrade the energy efficiency and heating systems of qualifying households.

The scheme, which began in April 2025 and is set to run until 2028, is targeted at energy-inefficient households that are deprived, low-income, or receive a means-tested benefit.

In its latest funding round, the programme awarded £13.9 million to a consortium that included every council in Surrey.

So if you’re eligible and live anywhere in Surrey, you could get up to £30,000 worth of measures.

This includes £15,000 for energy performance upgrades such as a solar & battery system, and another £15,000 for a low-carbon heating system, like a heat pump or electric storage heaters.

How many homes in Surrey have solar panels?

32,043 homes in Surrey have had solar panel systems installed, according to the latest government data.

This means 6.7% of the county's 481,818 households have gone solar – which is higher than the UK average of 6%.

Is Surrey sunny enough for solar panels?

Surrey is absolutely sunny enough for solar panels. In fact, it gets more sunlight than most of the UK, receiving 1,276 kilowatt-hours per square metre (kWh/m²) per year – 16% above the national average.

This figure will change a bit depending on where you live in Surrey, but it’s certainly an encouraging indicator.

In the solar industry, amounts of sunlight are measured via ‘solar irradiance,’ which tracks the sun’s average intensity in a specific place.

It’s measured in kilowatt-hours per square metre – meaning how much energy makes it from the sun, through 93 million miles of space, to a certain square metre on Earth.

As you may expect, the more intense the sunlight that hits your panels, the higher the kWh/m², and the more solar electricity your system will generate – meaning higher savings for your home.

Typical solar panel output in Surrey

These output figures are all based on a solar household in the centre of Surrey.

We've chosen a 4.95kWp system because it should generate more than enough electricity to match the average UK household's electricity consumption, which is 3,400kWh per year, and because it was the average system size in 2025, according to the MCS.

Whenever your solar panels produce more electricity than you can use or store in your battery, you can sell this excess energy to the grid via one of the best SEG rates.

While almost all UK systems do this during summer, households in Surrey should be able to benefit from this extra income stream more often.

Please note: you won’t necessarily produce as much solar electricity with your system, since your home will have its own unique characteristics – but this should give you a good idea of what’s possible in Surrey.

How many solar panels do I need in Surrey?

There's no ideal number of solar panels for any home, but it usually makes sense to get as many as you can fit on your roof.

Solar panels are cheap compared to the large, fixed costs of installation, like scaffolding and labour, and each extra panel adds to your output – and therefore your savings.

However, it's worth taking a look at how many panels you'd need to produce as much electricity as you use.

The average Surrey household consumes 4,267kWh per year, based on our analysis of the latest government data.

If you want a system that'll produce at least this much electricity in typical Surrey irradiance and on a south-facing roof, you’ll need 10 panels, each with a 450W peak power rating.

An east- or west-facing system would require 12 of these panels.

Connecting solar panels to the grid in Surrey

To connect solar panels to the grid, your installer must contact your Distribution Network Operator (DNO).

These organisations run the hardware that supplies your area of the country with electricity, so they need to know how much energy is flowing in and out of the grid.

The two that serve Surrey are UK Power Networks (UKPN) and Scottish and Southern Electricity Networks (SSEN). Which one covers your area depends on where you live, and you can find out here.

If your inverter’s capacity is 3.68kW or less, your installer can simply notify your DNO after they've connected your system to the grid, with a G98 application.

As long as it's filled in correctly, a G98 is just a formality, which is why these installations are often called 'connect and notify'.

If your inverter’s capacity is above 3.68kW, your installer would instead ask your DNO for permission to use the inverter's maximum capacity, via a G99 application.

Only when this submission has been approved – which most are – will you be able to sell all of your excess electricity to the grid, allowing you to make the most of your system.

Exporting your electricity is one of the largest financial benefits of going solar, as it can earn a typical home £675 per year on the current best tariff combination.

Planning permission for solar panels in Surrey

There are currently 255 active conservation areas in Surrey, according to the government's most recent data.

You can get solar panels installed in a conservation area without planning permission in the majority of cases.

This is thanks to permitted development rights, which enable homeowners to make reasonable changes to a property without asking for permission.

In some conservation areas though, the local authority applies an Article 4 Direction (A4D) on building works, which can limit or remove its residents’ permitted development rights.

There are 110 A4Ds in Surrey, ranging from ones that only affect a few front gardens or shop fronts to one that covers a whole village.

They won't necessarily stop you from making any alterations, but may require you to get planning permission. To succeed, you'll have to explain that your solar panels won't affect the area's special character.

Fortunately, most households in Surrey can get solar panels without planning permission, including those in conservation areas.

Is it worth getting solar panels in Surrey?

It’s well worth getting solar panels in Surrey – more so than it is in the majority of the UK.

Surrey receives high levels of solar irradiance, particularly compared to the national average, which means its residents can save hundreds of pounds per year by going solar.

There’s a reason why 6.7% of Surrey's households have already switched to solar – and that percentage will likely rise in the coming years, as energy bills stay high, and heat pumps and electric vehicles become even more widespread across the country.

If you’d like to go solar but you’re put off by the upfront cost, consider Sunsave Plus, our all-in-one residential solar and battery solution that’s tailored to your home, and delivered as a monthly subscription with no upfront cost.

It also comes with the 20-year Sunsave Guarantee, which includes 24/7 monitoring, maintenance, a free battery upgrade, a free inverter replacement if necessary, and downtime cover. Your system will also be insured by Aviva against damage, fire, and theft.
