Do solar panels work in Scotland?
As is the case in the rest of the UK, solar panels are just as worthwhile an investment in Scotland. According to a 2025 report by the Resolution Foundation, an energy-efficient solar system can provide up to 24% in electricity bill reductions, and up to £670 in annual electricity bill savings. This pits the break-even point for a medium-sized Scottish home at around 8.
The cost of solar panels in Scotland has significantly decreased over the last few years, which makes solar panels accessible to every type of household in Scotland. Additionally, government grant schemes and incentives also provide partial or full coverage for solar system installations, reducing the break-even point on your total costs even further.
Despite less sunlight compared to southern areas in the UK, solar panels in Scotland still exhibit significant efficiency, as well as an opportunity to reduce your domestic carbon footprint for the benefit of the environment. Installing solar panels is easy since no planning permission is required beforehand.
You can use GreenMatch's solar panel calculator to estimate potential solar panel costs, savings, and break-even points based on your home address.
Are solar panels worth it in Scotland?
Solar panels operate with high efficiency in Scotland, despite fewer sun hours on average in comparison to southern areas of the UK. This is because solar systems do not technically require direct sunlight to generate electricity, although they will produce 10 - 25% of their normal output on cloudier days.
Many areas of Scotland still receive comparable amounts of sunlight as Southern areas of the UK, thus generating energy comparable to such regions, however, sun hours are not uniform across the country with many more northern areas getting less than ideal amounts of solar energy.
For most parts of the region, solar energy in Scotland can be harnessed with a 3kW or 4kW system just fine while meeting energy needs. The average energy consumption of a medium-sized home is about 2,700kWh (the national average according to Ofgem), and these solar panels can exceed this. However, areas further North may have less sunlight, which will require a more powerful system. This is one of the reasons why 5kW systems can be more useful in the region than, for example, southern England.
The extra output capacity is useful in covering the gap between the lack of sunlight and the home’s energy needs.
Cost of solar panels in Scotland
You might be wondering, how much do solar panels cost in Scotland? Solar panel systems in Scotland can cost anywhere between £2,500 - £10,500, covering 2kW - 6kW solar systems. For an average Scottish medium-sized home, a 4kW solar system costs around £5,500.
Solar system prices mainly vary depending on the system's output capacity suited for your energy needs. Factors such as additional panels, battery storage, and roof type can also affect the final price. Here’s a full breakdown of the costs of a full solar system in Scotland:
| Household size | Average annual home energy consumption | Solar system size | System cost | Electricity generated per year (kWh) | Annual savings |
|---|---|---|---|---|---|
| 1 - 2 bedrooms | 1,800kWh | 2kW | £2,500 - £3,500 | 1,700 | £450 |
| 1 - 2 bedrooms | 1,800kWh | 3kW | £4,500 - £5,500 | 2,550 | £450 |
| 2 - 3 bedrooms | 2,700kWh | 4kW | £5,000 - £6,000 | 3,400 | £670 |
| 2 - 3 bedrooms | 2,700kWh | 5kW | £7,500 - £8,500 | 4,250 | £670 |
| 4 - 5 bedrooms | 4,100kWh | 6kW | £9,500 - £10,500 | 5,100 | £1,020 |
A 3kW or 4kW system can comfortably meet the energy needs of an average 3-bedroom Scottish home, but lower outputs may be more appropriate if your annual energy consumption is less than 2,700kWh. For homes in regions of Scotland with more sunlight hours and/or lower energy consumption, a 3kW system might also suffice.
An average solar system price in the UK is around £5,000 - £6,000, however, your final investment will depend on several factors, such as the size of the system, its energy output, and the number of solar panels needed. A 4kW solar system will, on average generate 4,250kWh of electricity throughout the year.
If you know your household does not use much electricity, a 4kW solar panel system with a battery may be the better option for you. If your household uses more energy, for example, if you need an electric vehicle charging station, you may need a bigger solar system.
After years of falling prices, the average solar panel cost in Scotland and across the world has been on the rise again. According to UK Government statistics on solar photovoltaic costs, the median cost of installing a small solar system has surpassed £2,000, marking a 36% increase from 2022 price estimates. These cost increases are mainly linked to strained production resources and an increased worldwide demand for solar panels.
Many factors play a role in determining the cost of solar panels in Scotland, such as the system size and output, the type of solar panels, how many solar panels you need, and the solar battery price. Solar panels and solar batteries in Scotland can cost between £9,000 - £20,000 in combination

Are there any solar panel grants in Scotland in 2025?
In 2025, there are extensive government schemes and incentives for solar panel grants. These include local initiatives like the Warmer Homes Scotland programme or the Home Energy Scotland Grant and Loan, as well as nationally available grant schemes such as the Energy Company Obligation (ECO4).
In addition, there are certain financial incentives in place to encourage the transition to renewable energy sources, such as the Smart Export Guarantee and the VAT Reductions on energy-efficient systems, with the total scrapping of VATs for solar system installations.
Let’s take a closer look at each grant scheme and financial incentive program:
Home Energy Scotland
The Home Energy Scotland Grant and Loan program offers a combination of an initial grant and an optional loan on top of a range of energy efficiency upgrades. This program is a great option for those who do not qualify for a means-tested grant but still want cheap solar panels and to reduce energy bills.
For solar systems, a grant of £5,000 is available, followed by an optional loan. Applicants do not need to receive benefits to qualify, and all homeowners in Scotland are eligible for the loan. It’s important to know that the 0% interest loan is only available without the grant, and the scheme is only available for a combination of solar thermal and PV systems.
Warmer Homes Scotland
This programme offers funding up to £10,000, or more, to improve Scottish households that struggle with This programme provides funding assistance of £10,000 or more, for eligible households struggling with energy bills. A professional home survey determines the necessary efficiency upgrades per household, which may also include solar panels.
The eligibility criteria for the Warmer Homes Scotland scheme include:
- Being a homeowner or private rental tenant.
- Living in a home with a poor energy rating.
- Being a recipient of some passport benefits.
Households who don’t qualify for the Warmer Homes Scotland scheme may instead qualify for the Home Energy Scotland Grant and Loan. For this, you will need to contact the Home Energy Scotland administrators with a solar panel quote from an installer and they will assess whether you qualify for funding.
Energy Company Obligation (ECO4)
The ECO4 is a nationwide program that grants low-income and fuel-poor households the opportunity to replace inefficient heating systems. For solar panel grants in Scotland, there is the potential to receive coverage under the ECO4 scheme.
The eligibility requirements of the ECO4 expect households to meet the following criteria:
- Being a homeowner or private rental tenant.
- Being a recipient of means-tested government benefits (e.g. income support).
- Having an inefficient heating system with an EPC rating of D - G.
Beyond direct grants and loans, some other financial benefits and incentives in Scotland make installing a solar system worthwhile:
VAT Reductions
Scotland enjoys VAT reductions on the procurement and installation of energy-efficient systems, with a 0% VAT particularly on solar systems up until 2027. Until 2027. This results in savings of up to £2,850, compared to the original 20% tax rate.
Smart Export Guarantee (SEG)
The Smart Export Guarantee (SEG) allows homeowners with solar panels installed to earn money by exporting their surplus energy to the national grid. After installing your solar panels, energy companies can offer you export tariffs on surplus energy from your solar panels.
This extra earning can range from 1p - 30.3p/kWh depending on your energy supplier and contract, but even with an average tariff of 10.8p/kWh, you can earn back an additional £75 - £170 per year on top of your annual solar energy savings. This amount depends on how much more electricity you can generate above your home’s energy consumption.

Savings with solar panels in Scotland
In Scotland, solar panels can allow for savings of between £450 to £1,020. These calculations assume you can receive a decent amount of sunlight and have the appropriate system size for your home’s energy consumption.
Here’s a breakdown of the savings you can expect per solar system:
| Home size | Solar system size | Electricity generated per year (kWh) | Annual savings | Break-even point | Return on investment |
|---|---|---|---|---|---|
| 1 - 2 bedrooms | 2kW | 1,700 | £450 | 7 | £8,000 - £9,000 |
| 1 - 2 bedrooms | 3kW | 2,550 | £450 | 11 | £6,000 - £7,000 |
| 2 - 3 bedrooms | 4kW | 3,400 | £670 | 8 | £11,000 - £12,000 |
| 2 - 3 bedrooms | 5kW | 4,250 | £670 | 11 | £9,000 - £10,000 |
| 4 - 5 bedrooms | 6kW | 5,100 | £1,020 | 10 | £15,000 - £16,000 |
Solar PV panels in Scotland take between 7 to 11 years to break even, with an average of 9.5 years. Given that good solar panels generally last a minimum of 25 years before their efficiency gets too low, they will continue to generate savings and cut your electricity bills for a long time after the break-even point.
Pros and cons of solar panel installation in Scotland
All things considered, solar panels emerge as a wonderful segway into limitless green energy, bringing with it a whole host of benefits worth considering. Here’s just a few:
- Grant scheme support: Scotland has been particularly forward in empowering renewable energy through a series of local programs unavailable in the rest of the UK like the Home Energy Scotland grant, as well as national programs like the ECO4 that provide partial or full cost coverage for solar panel installation.
- Energy independence: As gas prices rise, there are very few signs that energy prices will return to the pre-energy crisis levels. That’s why renewable energy is a powerful tool for energy independence. Solar panels can harness the unlimited energy potential of the sun, freeing yourself from the insecurity of volatile energy markets.
- Extra earnings: With SEG tariffs, you can earn a significant amount of money by selling back surplus electricity to the national grid., Depending on what your chosen energy provider supplies, you can earn up to 30.3p/kWh with companies like Octopus Energy.
- Lower carbon footprint: By installing solar panels, you can help the environment by decreasing your carbon emissions and generating unlimited green clean energy. All the better if you can also provide surplus green energy back to the grid through SEG.
However, like any upgrade, solar systems can come with a series of drawbacks worth taking a look at. Here’s a breakdown of the key cons:
- High initial investment: While Scotland matches the prices in the rest of the UK and offers several grants, initial costs can still be high. Grants can help mitigate this, but not everyone is eligible for them.
- Varying sunlight: Sunlight hours in certain regions of Scotland can be lower than in the rest of the UK, which means you may need a stronger system. In these cases, a 5kW solar panel system may be more appropriate, which costs more than a 3kW or 4kW system. Regardless, most of the country can use 3kW to 4kW systems.
Solar panel installation in Scotland
As with solar panels in Wales, Ireland, and the rest of the UK, there is generally no need for planning permission when you install a solar panel system in Scotland, as long as they’re below a certain size. For the specific size, you should consult your local planning officer.
The process of installing a solar system is fairly straightforward in Scotland and follows the same guidelines as anywhere else in the UK. The installation should be carried out by an accredited professional. Here’s a breakdown of how the process looks:
- Finding an installer: It’s important to work with an accredited professional installer who can ensure that you receive a quality installation to bring you decades of energy security. If you’re wondering how much solar panels are in Scotland, get multiple quotes to find the right price bracket for you.
- Preparation: The installers will first set up scaffolding to access the roof. They may also clear away any obstructions and tend to any overdue roof repairs.
- Installing mounts: The mounts are what your solar panels are secured to. These are installed at an angle to maximise sun exposure and serve as the solid base for your solar array, keeping it secure in harsher weather conditions.
- Installing system: A PV solar system installation consists of several pieces, including solar panels, a solar inverter, a solar diverter, an optional solar battery, and all the necessary wiring to ensure everything is hooked up and functioning correctly.
- Finishing touches: Once everything is in place, the installer will test the panels to see if they function properly before handing them over to you.
If your home is a listed building, in a conservation area or a World Heritage Site, then you should also consult your local planning officer, there might be some extra precautions you need to take. In Scotland, solar panels can be installed in most places but it is still best to check the local regulations you might face for your area.
To make sure you get the solar system you want while keeping in line with solar panel size permissions, you will want to consult a professional installer who can offer you tailored advice.
