What's the average cost to have solar panels installed by Octopus Energy?

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 £6,264 (for 2 panels). A 10 panel installation and a 5kWh battery (our most popular system) costs £10,197. Our largest system, which includes 36 panels and a Tesla Powerwall battery costs £17,854 (all costs are based on July 25 prices).

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.
