How much does a solar system cost?

The price of a typical 4.2-kilowatt solar panel system is about £7,000.

The cost of a solar system will vary from household to household. This is because of differences in energy consumption, roof space, and personal preferences for solar panels.

We’d love to give you a cost price and a full proposal. To do this, we’ll talk to you first and assess your energy usage. We’ll then work out how many panels you might need to cover your average household bill and also let you know if you might benefit from a solar battery.

Will solar energy save me money?

If your energy bills are starting to get out of hand, solar is a great solution for generating your energy. The savings on your electricity bills will pay for the solar over time.

You can also earn money by exporting energy you don’t use back to the grid as part of the Smart Export Guarantee (SEG.)

You can expect to see average annual savings of over £800.

How long will it take to see a return on my investment?

The average time it takes to see a return on your investment in the UK has gone down to just seven years. This is because the average prices of energy have increased, while the cost of solar has dropped dramatically and solar has become more energy efficient.

You’ll see a quicker return on investment if you use appliances in the daytime. This is because you’ll effectively be using them for free when your panels are working. 

You'll also see a faster return on investment if you have a good SEG tariff. Octopus Energy offers an Agile Tariff and an Outgoing Octopus tariff. These tariffs net you 7.5p per kWh for every unit you export. These tariffs could see you earn over 50% more than other tariffs on the market.

We recommend shopping around to find an energy company that suits your needs.

Why does the cost of solar panels vary so much?

The cost of solar panels depends on the brand and type. 

There are two types of solar panels - monocrystalline and polycrystalline. Monocrystalline panels are slightly more efficient than polycrystalline, with efficiency rates of up to 24%.

Monocrystalline panels are usually black, while polycrystalline panels feature a dark blue colour. You might want to choose your panels based on aesthetics - another factor in the price of panels. Different brands will vary in looks as well as price.

In terms of efficiency, there are also variations in the size of some panels. You might have to go with a certain brand to get panels that fit correctly on your roof.

When looking to get a system installed at your home, look for leading reputable brands with high-efficiency rates. We use panels with a 25-year warranty for peace of mind and a long future of savings. 

We use brands such as:

How much will my electricity bill be with solar panels?

While this depends on each person, our solar specialists will always try to design a system that covers your energy usage each day. When using high-energy appliances such as washing machines, fridges, and tumble dryers during the day, you should expect your panels to cover this usage. Keep in mind that your panels won’t power your appliances in the nighttime unless you have a battery.

My energy bill is increasing. Is solar power the right option?

Since energy prices went up 54% in the UK in April, we’ve had a new interest in solar panels from those looking to cut down their bills. We would always recommend solar energy to those looking to future-proof their life. Unlike energy bills, the cost of free energy from the sun will never be subject to spikes or changes. 

Are solar panels still a good idea in the UK?

Solar panels are a great idea for the UK. Solar panels work all year round as they generate energy from UV light rather than heat. This means that cloudier UK weather won’t affect your solar panels. 

With the energy crisis in the UK still ongoing, and prices rising again in October, solar panels could be the solution to your high energy bills.
