What's the average cost and payback period?

×

Average cost

The cost of installation can depend on how many panels you need, whether you choose to have battery storage and what size of battery you require. The cost of a panel-only installation by Octopus starts from £3,880 (for 2 panels). A 10 panel installation and a 5kWh battery (our most popular system) costs £9,199. We'll ask you to pay a fully refundable deposit of £500 when you agree to your quote, then you’ll have the option to pay monthly with a fixed-term loan, or pay in full after installation.

Fill out this quick form for a personalised cost estimate.

How long will it take for my solar system to pay for itself?

We compared the typical installation cost and annual bill savings for our most common solar system (10 panels, 5kWh) in 5 different scenarios. The payback period varied from 9 - 12 years depending on the energy tariff.

Of course, each home is unique and this can be influenced by lots of different factors.

We’ll calculate a personalised payback period following our design consultation to give you an insight into what you might save for your home.

Are solar panels right for my home?

×

Before going ahead with your installation, we'll need to check a few things first. First, you will need a clear space on a pitched roof (not flat) that can fit at least 2 solar panels. See our FAQ on how much space you'll need for more info.

It's important that this part of your roof sees the sun throughout the day, so a north facing roof may be unsuitable. We'll also need to be able to install scaffolding below this part of the building in order to complete the installation.

Next, you'll need to decide if solar panels make money-sense. The higher your energy usage at home, the more beneficial solar panels and a battery will be (you'll be saving the money you would have otherwise spent on bills, and this will go towards paying back the cost of your solar system). If you have a low usage, it's worth keeping in mind that your payback period will be longer, but this is something we can discuss in your consultation.

Finally, please note that we can't install on properties with a 3 phase electricity meter just yet, but we are working hard on a solution.

In the table below, you can check out the typical costs, savings and payback period for an average customer with our most popular system size (10 solar panel & 5kWh battery). Check out this blog for more on solar savings.
