Should you buy solar panels if you live in Dorset?

You should absolutely buy solar panels if you live in Dorset and can afford it.

The county’s beaches are popular for a reason, with Dorset receiving more sunshine than most places in the UK – meaning solar panels create more electricity here.

A typical three-bedroom household in Dorset will cut its annual electricity costs by 79% and break even in 13.08 years – which is quicker than the UK average.

You’ll then have at least another 12 years to enjoy free electricity and build up your savings, which is why the average Dorset home with solar panels can expect to make a total profit of £6,425 after 25 years.

Solar panels can also massively reduce your carbon footprint here. A three-bedroom household can expect to cut its emissions by 13.25 tonnes of CO2 after 25 years.

As long as you can afford how much solar panels cost, they’re an excellent investment.

How much sunlight does Dorset receive?

Dorset receives 12% more sunlight per year than the UK average, according to the European Commission.

This means it’s one of the best places in the country to own solar panels – in fact, only Brighton, Southampton, Plymouth, and East Anglia enjoy more sunlight than Dorset.

That’s why there are so many solar farms here, because compared to their counterparts in North Scotland, people in Dorset receive 33% more sunlight.

This allows them to break even about four years sooner than solar panel owners in Inverness..

But wherever you are in the country, solar panels work in the UK – solar panels work on cloudy days and even in snowy weather.

How much does it cost to install solar panels in Dorset?

It costs £705 to buy and install a 350-watt solar panel in Dorset, on average.

A typical three-bedroom household will therefore pay £7,050 for an array with 10 solar panels, which is usually enough to cover the home’s solar electricity needs.

Are there any solar panel grants from local councils in Dorset?

From April 2023 to March 2025, some homeowners in Dorset can get heavily subsidised or even free solar panels through the Home Upgrade Grant.

The UK government has handed Dorset Council £4.3 million to help improve the energy efficiency of homes in the area.

To qualify for funding, your household must earn a total gross annual income under £30,000, and your home must have an Energy Performance Certificate (EPC) rating of E, F, or G.

28% of grants handed out nationally have been for solar panels. On average, they cover 86% of the cost of the panels and installation – though in many cases, the council will cover the entire bill.

A typical three-bedroom household receiving free solar panels would save £15,000 on its electricity bills over the next 25 years.

So far, 1,181 homes in the South West have signed up to receive funding from this scheme, which also grants for insulation, heat pumps, double glazing, solar thermal, and heating controls.

You may also be able to access national solar panel grants like the government’s ECO4 scheme.

How many homes have solar panels in Dorset?

13,038 homes have Microgeneration Certification Scheme-certified solar panels in Dorset.

That total represents 8% of all households in the area – well above the national average of 4.5%.

And that’s just MCS-certified installations. The actual number will likely be higher, as not every solar panel system is certified by the MCS.


So there you have it: Dorset is one of the best places in the UK to have solar panels.

Households will typically save more and break even sooner than homes in the rest of the country – and some may even be able to get free solar panels.

With our help, it’s simple to compare solar panel prices. All you have to do is provide a few quick details, and our expert installers will be in touch with free quotes for you to compare.


Yes, it is still worth installing solar panels in the UK.

The average three-bedroom household can save 70% on its electricity bills with a 10-panel system, and break even in 14.55 years.

And the UK is only getting sunnier as solar panels get more powerful and efficient, so homes will continue to generate an increasing amount of free energy moving forward.

The average cost of installing solar panels in the UK is £7,026 for a three-bedroom household.

A household with one or two bedrooms will likely need six solar panels, which typically costs £4,216.

A larger house with four or five bedrooms would usually need 14 solar panels, which costs £9,837, on average.

Some households can get free solar panels in the UK through the Energy Company Obligation scheme (ECO4) or the Home Upgrade Grant.

ECO4 compels energy suppliers to provide upgrades to energy-inefficient households on certain benefits, including installing solar panels on homes with electrically powered heating.

The Home Upgrade Grant has enabled certain local authorities to provide grants of up to £10,000 to low-income homes in their area with an EPC rating of D, E, F, or G for improvements including solar panels.
