Great experience from start to finish, the guys look after me every step of the way. Joe Middleton and Antony Francis were incredible… they both deserve a huge pat on the back for helping me through the whole process. The installation team were brilliant and overall would HIGHLY recommend using Octopus for your solar. Very happy customer and over the moon with my install :)

Octopus energy have exceeded our expectations… I had no chasing to do, Nikhil was on the ball every step of the way! The attention to detail was second to none… A very tidy installation! The roofers fitting the solar panels even made sure our guttering was clear! Thanks for that!!!! Today the scaffolding was removed incredibly swiftly and cleaned up after themselves. We highly recommend Octopus energy for Solar Panel, battery and inverter installations! 10/10

Frequently asked questions
If your question isn't answered here, check out our full FAQ page for more.
How will I receive my £500 discount from Octopus?
If Santander validates you as an eligible customer, a £500 discount will appear off your final sales agreement price with Octopus.
What's the average cost for standard installation?
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 £4,100 (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 the remaining balance can be paid after install.
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.
How long will it take for the panels to pay for themselves?
Our systems typically pay for themselves in 9 - 11 years.
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 - 11 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 let you know what you might save for your home.
Is my home suitable for an Octopus solar installation?
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.
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.
Does the solar system come with a warranty?
All of our equipment comes with a manufacturer warranty:
- Solar Panels: 25 years product warranty and 30 years linear power warranty.
- Inverter: Enphase Microinverters come with a product warranty of 25 years, whilst the GivEnergy inverter is covered by a 12 year product warranty.
- Batteries: 12 years for GivEnergy products and 15 years for Enphase products.
Our customers are also protected by a 2 year Workmanship Warranty Insurance scheme.
Our claims explained
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.
