Average costs
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 £200 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.
Find out how long it takes for a solar system to pay for itself.
What does a standard installation include?
Your quote will be inclusive of your chosen number of solar panels and battery option, microinverters (if necessary), bird protection and all other electrical components required to complete the install. Plus scaffolding, delivery and labour costs, and our 5-star customer support from start to finish.
For an Octopus solar installation, you will need to own your home, and you will need a clear space on a pitched roof (aka not flat) that can fit at least 2 solar panels. See our FAQ on how much space you'll need for panel sizes.
Please note that we're not able to install solar for flats or properties with a 3 phase electricity meter just yet. And at present we are only able to install system systems on roofs with clay or concrete roof tiles.
It's important that this part of your roof sees the sun throughout the day, so a north facing roof will generate less power, and could be unsuitable. We'll also need to be able to install scaffolding below the roof where the panels will be fitted in order to complete the installation.
If Octopus are unable to install solar at your home, we may be able to recommend an Octopus Trusted Trader to complete the job for you, with equivalent care and quality.

Cut up to 91% off your electricity bills
We compared the annual cost a typical household would pay for their electricity on the July '24 price cap - £1,002, to what they would pay with a 10 solar panel & 5kWh battery system (our most popular system) on our Octopus Flux tariff - £93. This is a saving of £909 or 91% of your total electricity bill.
In this table, 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 and a more detailed explanation of our calculation.
