How much does it cost to install solar panels in the UK?

If you’re thinking about installing solar panels you’ve probably already heard about many of the benefits.

They can reduce your utility bills at a time when costs are skyrocketing, they give you more independence from the national grid, they add extra value to your home. 

And let’s not forget the most obvious advantage of all – they reduce your carbon footprint and help to save the planet.

But what about the ins and outs of actually installing solar panels? We all know that it costs money to get started with solar power, but how much does it cost to install solar panels?

Well, let’s take a look at those questions a little more closely…


How much does it cost to install solar panels? 

Installing solar panels can have varying costs. 

It all depends on how much your installer charges for materials and labour. 

85-90% of the cost of your installation will go towards buying the materials, including panels, brackets, and an inverter.

The other 10-15% of the cost goes towards paying for labourer’s fees.

Solar panel costs

How much does it cost to install solar panels? Well, it depends on a few factors.

  • First of all, what type of solar panels do you want?

There are different types of solar panels which are more suitable for different needs. 

  • How much energy do you want to generate?

Before you invest, take a close look at your electricity bills and your annual electricity usage. 

The ‘efficiency’ of a solar panel refers to how much sunlight it can convert into electricity, represented as a percentage. 

If a solar panel has 19% efficiency it means it can convert 19% of all sunlight received into electricity for your home.

There are solar panels on the market at the moment that are around 24% efficient, but the average is between 15% and 18%.

Find a system that generates enough power to meet your household’s needs. Every home is different. If you need help deciding, ask our friendly team of consultants.

  • What size and type of property do you have? 

If your household uses a lot of electricity, logically you will need to install more solar panels. How much it costs to install solar panels depends largely on how many panels you need. Ultimately, however, you will save more money if you need more electricity produced.

  • What direction does your roof face in?

In order for your solar panels to be a worthwhile investment, you need to consider your roof space.

If your roof is covered in shade, it may not be suitable for solar panels. The ideal roof is south-facing at an angle between 10 and 60 degrees, although easterly and westerly facing rooftops can also be used.

 A solar panel system typically weighs about 200 kg, so get a professional to assess your rooftop to see whether it is capable of bearing the extra weight.

The good news about solar panels is that, although they can cost quite a bit at the beginning, they eventually pay themselves off.

If you get an SEG Licence then you can receive payment for the electricity you export back to the National Grid.

Depending on your circumstances and needs, you could save up to £360 a year and recuperate your investment within 15 years.

Another piece of good news is that solar panels are now cheaper than ever, as the government has cut the VAT rate on energy-saving materials to 0% from 2022 to 2027. 

So how much does it cost to install solar panels? 5% less than it did before!


Extra Costs 

If you’re asking the question ‘how much does it cost to install solar panels?’, you’d probably be interested to know about any extra charges that might be involved.

We want to be upfront about the reality of the costs, so here are some extra points you need to take into account.

  • Adding a Solar Battery

If you’re asking how much does it cost to install solar panels you might not realise that there can be extra costs.

One such extra cost can be adding a solar battery onto your solar panel installation.

They are worth the investment, as they store any unused energy accumulated into the battery, meaning you won’t need to revert to energy from the grid at nighttime. 

You will also have power stored in the event of extreme weather conditions, or should your solar panels not have access to sunlight for some reason.

  • Solar Panel Inverters

When asking ‘how much does it cost to install solar panels?’ another extra cost to consider is that of solar inverters.

They are integral parts of any solar panel system, as they convert electricity from direct current (DC) to alternating current (AC) before it can be used in your home.

They are slightly less durable than solar panels. While solar panels can endure between 25 to 30 years of service, solar inverters should generally be replaced after 10-15 years.

  • Maintenance and Repair

One of the ongoing costs of solar panels is, of course, the cost of maintenance and repair.

You’ll be glad to hear that solar panels rarely break as they don’t have any moving parts, and their surfaces are built to withstand hailstones the size of golf balls.

It is not impossible, however, that they may break and therefore it’s wise to be prepared.

Sometimes solar panels break due to falling debris like tree branches or stray cricket balls. Small animals may chew through wiring, and most likely of all, extreme weather conditions can damage the panels.

Solar panels are complex electrical devices and so, in the event of damage, you should get a professional out to inspect and fix them.

In terms of cleaning, UK rainfall is usually enough to do the trick. Occasionally you might need to rinse them down with lukewarm water, but there’s not a great deal of cost involved in that.
