Yes, Octopus Energy Solar can be worth it for many UK homes.
It’s best suited to households with good roof space, daytime electricity use, or a home battery.
Solar panel systems typically cost several thousand pounds upfront.
Adding a battery increases the cost but can significantly improve long-term savings and payback.
Most solar systems pay for themselves in around 8–12 years.
Payback can be faster if you use more of your own solar power and earn money through export payments.
Yes, Octopus Energy offers Smart Export Guarantee (SEG) tariffs.
You’re paid for unused electricity you export back to the grid, helping offset installation costs.

Switching to Octopus Energy Solar is one of the smartest ways to cut your energy bills, reduce carbon emissions, and take advantage of green energy. With Octopus Energy, you can install solar panels, connect your existing system, and even earn money for the energy you export back to the grid.
For many UK households, Octopus Energy Solar is worth it, particularly if you have good roof space, use electricity during the day, or plan to add a battery or EV. Savings depend on installation cost, how much energy you use yourself, and how much you export back to the grid.
Costs vary based on:
System size (kWp)
Whether you add a battery
Your property and roof type
As a rough guide:
Solar panels only cost several thousand pounds
Solar + battery systems cost more upfront but can increase long-term savings
Exact pricing is provided through an Octopus Energy solar quote.
The typical payback period is 8–12 years. This can be shorter if you:
Use more of the electricity you generate
Add battery storage

Smart tariffs and higher electricity prices can also improve payback.

Key points:
You’re paid for each unit of electricity you export
Payments depend on the SEG tariff you choose
A smart meter is required to receive export payments
SEG income can help offset your solar installation costs over time.

While solar installations themselves may not always include direct cashback, switching your energy supply through Octopus Energy Cash can unlock switching cashback, helping reduce your overall energy costs alongside your solar setup.
Availability and terms of cashback offers may change, so always check current offers before switching.
