Good Energy Export Rates for Solar Panel Owners

As a 100% renewable supplier, it suits owners who want both their import and export to be green.

As a 100% renewable supplier it appeals to owners who want their export and import both green.
Good Energy SEG Export Tariffs
Like most large UK suppliers, Good Energy publishes more than one Smart Export Guarantee rate. The higher rates come with strings attached, usually that you take Good Energy for your import electricity too, and sometimes that they installed your system. Here is every published tier.
| Tariff | Export rate | Type | Who can get it |
|---|---|---|---|
| Solar Savings Exclusive | 25p/kWh | Fixed term | Good Energy-installed systems |
| Solar Savings | 15p/kWh | Variable | Good Energy import customers |
- Solar Savings Exclusive: Highest flat SEG rate on the UK market. Fixed for 12 months, then rolls onto Solar Savings (15p). Requires solar and a battery installed by Good Energy Solar, plus Good Energy import.
- Solar Savings: 15p/kWh for any Good Energy import customer with solar; no Good Energy install required.
Good Energy Import Prices for Solar Homes
Your export rate is only half the story. What you pay to import electricity at night and on dull days matters just as much, and in the UK you can choose to keep your current import supplier and take an export tariff elsewhere. Good Energy's standard variable import prices track the Ofgem price cap. Here is the cap level for 1 July to 30 September 2026 alongside an estimated annual import cost at typical usage (2,500 kWh).
| Import unit rate | 26.11p/kWh |
| Standing charge | 57.19p/day |
| Est. annual import cost | £861 at 2,500 kWh/yr |
Ofgem price cap, GB national average, direct debit, incl. VAT, for 1 July to 30 September 2026. Actual prices vary by region and payment method. Before solar self-consumption and export credit.
What Good Energy Export Pays You
Annual export earnings depend on system size and how much of your generation you self-consume. These figures use Good Energy's best rate that does not require buying an install from them.
| System size | Typical annual export | Good Energy earnings (15p/kWh) |
|---|---|---|
| 3.5 kWp (8 panels) | 1,600 kWh | £240 |
| 4.5 kWp (10-11 panels) | 2,000 kWh | £300 |
| 5.4 kWp (12-13 panels) | 2,400 kWh | £360 |
| 6.4 kWp (14-15 panels) | 2,900 kWh | £435 |
| 5.4 kWp + battery | 1,400 kWh | £210 |
A battery cuts your export volume because you self-consume more, but raises the share of your bill you avoid at the much higher import rate. See our battery storage guide for the trade-off.
How SEG Payments Work with Good Energy
- Your system is MCS-certified. SEG payments require an MCS (or equivalent) certificate for the install and installer. Good Energy cannot pay SEG without it.
- You have a smart meter recording exports. SEG pays for measured half-hourly exports, so you need a smart meter with an export reading set up.
- You apply to Good Energy for SEG with your MCS certificate, MPAN and bank details. You can do this even if Good Energy is not your import supplier.
- Export credit is paid quarterly bill credit as a bill credit or bank payment.
- Payments continue automatically unless you switch export supplier or move home.
