Best Tariffs for Solar Owners
Octopus Energy offers the most competitive export rates in the UK market. While the industry-standard Smart Export Guarantee (SEG) pays just 4.1p/kWh, Octopus's export tariffs pay significantly more — up to 3x as much with Outgoing Octopus, and potentially even more with Flux's optimised timing.
For detailed breakdowns of each option, see our Octopus Flux guide and the full tariff comparison.
Octopus Solar Panels
Octopus Energy installs 450W all-black solar panels with industry-leading warranties: 25 years on the product and 30 years on power output. The all-black design is both aesthetically pleasing and high-performance, and they suit most UK roof types.
System prices range from £6,163 for a 2-panel system up to £9,691 for 8 panels with a 5kWh battery. Octopus has partnered with DivideBuy for finance options, requiring just a £200 refundable deposit to get started. A remote survey option means you can get a quote without an in-home visit.
Battery Storage — Tesla Powerwall 3
For maximum savings and earnings, pairing solar panels with battery storage is essential. Octopus Energy offers the Tesla Powerwall 3 with 13.5kWh of storage capacity — enough to power an average UK home for a full evening and overnight.
With a battery, you can store excess solar generation during the day for evening use, charge from the grid during cheap overnight periods, and export to the grid during expensive peak hours via Octopus Flux. The top 12% of Flux users earn £314+ per year in net profit.
Savings Potential
Combining solar panels, battery storage, and the right Octopus tariff can reduce your energy bills by up to 90%. The typical payback period is 9–11 years, after which the system generates pure savings for its remaining 14–16 year warranted lifespan. Octopus has already paid 100,000+ solar homeowners for their exported electricity.
Solar panels also add approximately 2–3% to your property value and save roughly 1 tonne of carbon annually — especially impactful when paired with Octopus's 100% zero-carbon grid electricity (0 g/kWh vs the UK average of 154 g/kWh).
100,000+ Solar Homeowners Paid
Octopus Energy has paid over 100,000 solar homeowners for their exported electricity — demonstrating the scale of their commitment to distributed renewable energy. They source from 700+ UK renewable generators and invest in 240+ renewable energy projects with £6 billion in combined assets.
Whether you're installing new solar panels or looking for a better export deal for an existing system, Octopus offers the most competitive rates in the market. Read our full Octopus Energy review or explore the complete guide library.
