Under the Smart Export Guarantee, electricity suppliers offer payment for each unit of power you export to the grid. Our league table reveals which suppliers are offering the best rates. Note that the best rate may not always mean the best energy package. Solar Energy UK recommends shopping around for the best deal.
The highest rate is Tesla’s (administered by Octopus) – but it requires you to buy a Powerwall 2 solar battery, which currently costs around £9,000 to install. Octopus offers the next best SEG rate, paying out 15p for every kWh of renewable electricity a household sends to the Grid.
With the best Smart Export Guarantee tariffs in 2024, you can transform your solar panels into a revenue stream. Let's recap on what we've learned: Octopus Energy leads the charge with competitive rates up to 24p/kWh for their customers. OVO Energy and E.ON Next follow closely behind, offering attractive rates.
The rate mentioned, 20p per kWh, is based on the latest available data, but energy market rates are subject to fluctuation. E.ON offers the Next Export Exclusive tariff under the Smart Export Guarantee (SEG) scheme. This tariff provides a rate of 16.5p per kWh for electricity exported back to the grid.
The best overall export tariff is Intelligent Octopus Flux. With this tariff, customers who choose Octopus as their energy supplier can typically gain 29.4p for every kWh (kilowatt-hour) of solar electricity they export between 4pm and 7pm, and 22.1p per kWh at all other times.
The best SEG tariff currently available is Octopus Energy's Intelligent Octopus Flux, which provides up to 30.31p/kWh for customers with solar panels and compatible batteries. This tariff stands out in SEG tariff comparisons as one of the best export tariffs for solar panel owners.
