How Much Does It Cost to Install Solar Panels in the UK?
In 2021 solar panels cost around £6,000 – £7,000 for the average sized residential home, this is over 60% cheaper compared to what they were in 2010. It means solar panels are now more affordable than ever. And that’s great news for homeowners!
Even though there’s never been a better time to invest in solar energy, solar panels are a considered purchase. It’s not like nipping out to the shop to buy a new pair of shoes. Although prices have dropped a lot, systems still cost several thousands of pounds. So it’s important to do your home work around not only which are the best solar panels, but also how long it could take to recoup your investment through energy savings and government payback. Use our solar PV calculator to find out how much payback you can expect.

Solar panel systems come in different sizes that determine just how much electricity it’s able to generate. Simply put, the larger the system, the more electricity your home will benefit from. Find out just how much solar panels cost in the UK with the table below:

To put these prices into context, the cost of solar panels for a 3 bedroom house will be around £5520 – £6040 as they’ll need to install a 3-4kW system to meet the higher electricity demands.
For most people though it’s not how much they are willing to pay for a solar PV system, but rather how much they can afford to pay. Now that systems are cheaper, solar panels have become more affordable, meaning more people can invest. Solar panels have become the most accessible of all renewable energy technologies.
Solar panel costs will depend on the size of the system you have installed, the installer fitting them, and the brand and quality of the panels themselves. For example, black monocrystalline silicon solar panels (the black ones) are slightly more expensive compared to polycrystalline silicon solar panels, which are characterised by their marbled blue appearance.
As we mentioned earlier, the price of solar panels has dropped pretty significantly. In fact, solar panel prices are 70% cheaper than in 2010. We’ve included a chart below to illustrate just how much prices have dropped for a typical 4kW system in the UK.

How many people are having solar panels installed?
Residential solar panel installations saw a huge peak in the 2015/16 financial year, with 95,122 0-4kW solar systems installed. Installations have dropped off a bit since then but are beginning to rise again with 32,370 installed in 2018/19 compared to 19,708 the year before.
With prices at a much lower level than they were around 10 years ago, it’s no surprise that the number of installations is beginning to rise again.
