How Much Do Solar Panels Cost in the UK?
The cost of a solar panel system in the UK is primarily determined by the size of the solar installation. As a general guide:
- Small system (6 panels / ~2kWp): £4,000–£5,500
- Medium system (12 panels / ~4kWp): £6,000–£8,000
- Large system (16–25 panels / ~8kWp): £8,500–£13,000
Most homes need a system of between 10 and 16 panels to significantly offset their electricity usage. A qualified solar installer will assess your energy consumption, roof space, and orientation to recommend the most cost-effective solar panel system for your home.
What Does the Cost of Solar Panels Include?
A full home solar installation quote should include:
- The solar panels themselves. The photovoltaic (PV) modules that capture sunlight and convert it to electricity. Panel quality and efficiency ratings vary, so it’s worth ensuring you’re getting a proven, high-performance product, whether polycrystalline or monocrystalline.
- An inverter. Solar panels generate direct current (DC) while home appliances use alternating current (AC). An inverter converts the energy, so it can be used around your home. The type of inverter can affect both performance and solar panel cost.
- Mounting and racking. The hardware used to safely fix panels to your roof.
- Experts come in for installation. They usually wrap it up in a day or two for a regular home.
- Today’s systems often come with software that lets you check on how much power you’re making and using anytime you want.
Make sure the quote breaks down what’s in it so you know what you’re paying for.
What Can Change How Much Solar Panels Cost?
Besides how big the system is, other things can change the final price tag:
- Roof type and complexity: A plain old sloping roof is pretty easy and cheap to work with. But if you’ve got a flat roof, a quirky design, or anything that needs a bit more reinforcement, expect to shell out a bit more.
- Panel efficiency: More efficient panels can squeeze more juice out of the sun. They cost more up front, but you might need fewer of them. This often pays off in the long run.
- Inverter type: Your standard string inverters work well, do the job, and won’t break the bank. For shaded roofs, you might need those nifty microinverters or optimisers. They help when there’s shade, but they do cost extra.
- Location: What you’ll pay for labor can shift a bit depending on where you are in the UK.
- Scaffolding: Most times, you’ll need some scaffolding set up. Make sure your quote covers it.
How Much Can Solar Panels Save You?
You’ve got to look at solar panel costs against what you’ll save over time. A medium-sized setup might trim your yearly electric bill by £500 or maybe £1,000. It all kind of hinges on how much power you’re burning through, the size of your solar array, and whether you have a battery.
As those panels keep working for 25 years, you might see savings from £12,500 to possibly even £25,000 or more. That’s usually way better than what you put in at first. Is solar a good buy? Many people say yes.
Should You Add a Solar Battery?
Adding a battery storage system to your solar installation maximises the value of your investment. Solar panels generate the most electricity in the middle of the day, often more than a household uses at that time. Without a battery, that surplus energy is exported to the grid. With one, it’s stored for evening use when your panels aren’t generating.
A solar battery typically adds £2,000–£4,000 to the cost of an installation but increases the proportion of your own solar power you actually use from around 30% up to 85%. For many households, the addition of a battery significantly accelerates the payback period.
Earning Money Back: The Smart Export Guarantee
The Smart Export Guarantee (SEG) means that any solar electricity you don’t use and don’t store can be sold back to the national grid. All major energy suppliers are required to offer an export tariff, providing an ongoing income stream on top of your bill savings.
Rates vary between suppliers, so it’s worth comparing tariffs to ensure you’re getting the best deal on the energy you export. Net metering is an effective way to earn money back from your solar system.
Finance Options: Making Solar More Affordable
Concerned about the upfront cost? At Greener Energy Group, we offer flexible funding options so that more homeowners can access the benefits of solar without delay:

- If you’re a homeowner in Scotland, you might qualify for the Home Energy Scotland Loan. You could get an interest-free loan backed by the government for up to £15,000. There’s also a chance for cashback up to £2,500 if your installation qualifies.
With options like these, solar panel cost doesn’t have to be a barrier to entry.
How Long Until Solar Panels Pay for Themselves?
The payback period for solar panels in the UK often falls between 8 and 12 years. It depends on system size, how much energy you use, the export rates, and if you have a battery. Solar panels last over 25 years and need barely any maintenance. Most folks enjoy more than ten years where their electricity is basically free once they’ve covered the costs.
Solar panels also add an estimated 4% to the value of your home, meaning that even if you sell before the payback period is complete, you’re likely to recoup a significant portion of your investment through the increased sale price.
