How much do Solar panels cost?
Understanding solar panel pricing can be a minefield. With 100s of brands and installation options, you need to know what you’re getting for your hard-earned cash, and why price can vary so much.
What Affects Solar Panel Installations Cost in the UK?
Your Aims
This is the most overlooked factor. And probably the most important. What do you want to get from solar? Do you have a fixed budget and want to get the highest power system you can afford? Do you want the most effective system so you can be as energy independent as possible? Do you want to be as green as possible? Is peace of mind through extended warranties & durability top of your list? Or is payback period/ROI your top priority? Are you keen to take advantage of Solar Grid Trading? It’s normally a combination of these. Naked Solar will help you balance these priorities to choose the system that best fits your desires.
Your Building
The size of your building, available roof space, roof pitch, roof orientation (north facing is less efficient than south facing, for instance see our environmental factors page for a full explanation), shade from trees or adjacent buildings and ultimately where you live in the UK…All of these factors and more affect the amount of energy you can generate from solar panels and therefore the price of the system needed to power your home or business. We don’t sell “one size fits all”. We help you find an exact match for your specific requirements.
Your Energy Profile
How much energy you use, the way you use it, and when, will also influence the type of solar panel installation you choose. For instance, you can make huge bill savings by using high drain devices such as washing machines and dryers at different times of the day. And it may make sense to couple your system with a storage battery. If you’re a low energy user, a simple system might be enough for you. Our powerful PV Sol software can analyse all this and help you narrow down the options.
That’s why at Naked we never sell packaged deals. We take all these factors into account and present you with options to help you find the right system for you.

While understanding solar panel installation costs is essential, the real question is: when will your investment pay for itself? The payback period for solar panels in the UK typically ranges from 7-12 years depending on:
- Your Solar system size
- Energy usage profile
- Whether you include battery storage.
For businesses, economies of scale mean larger installations often see faster returns.
Solar Panel Cost vs. Long Term Savings
If you combine an energy efficient solar panel system with a good solar storage battery you can save up to 95% off your electricity bills and drastically reduce your carbon footprint.
Understand the True Cost of Solar Panels in the UK
When evaluating the cost of solar panels in the UK, it’s important to look beyond the initial installation price. While budget systems start from around £3,100 for home installations, premium systems using high-efficiency panels offer better long-term returns through increased energy generation and extended warranties.
Factor in the 0% VAT on residential installations (saving 20% immediately), government incentives through the Smart Export Guarantee, and rising energy prices, and most homeowners find their solar panel investment pays for itself within a decade while protecting against future electricity cost increases.
