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.

There are 3 main factors that affect solar panel choice and price…

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 your top priority?  It’s likely a combination of many of these.  At Naked Solar, we help you balance these priorities to find the system that fits your aims.

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 an 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 particular systems at you. We take all these factors into account and present you with options to help you make an informed choice.

That’s all very nice, but how much do they cost? Glad you asked…

The prices below cover budget options through to premium for home and business solar arrays. The variation in price reflects the choice of panels and inverters available.  Not all solar panels are the same.  Higher prices reflect the quality, longevity, efficiency and warranties of the products on offer.

These prices include all installation costs, certification, registration etc, you only need to add scaffold prices.
