The Smart Export Guarantee (SEG)
The SEG requires licensed energy suppliers with 150,000+ customers to offer export tariffs. You're paid for every kWh of surplus solar electricity exported to the grid. Rates vary from 3-15p per kWh depending on your supplier and tariff type.
How Much Can You Earn?
A typical 4kW solar system exports 1,500-2,500 kWh/year (depending on battery storage). At average SEG rates of 5-8p/kWh, that's £75-£200/year in export income. Some time-of-use tariffs like Octopus Flux pay more for peak-time exports.
Requirements for SEG
To qualify, you need: 1. An MCS-certified installation. 2. A smart meter or export meter. 3. A system up to 5MW capacity. Your installer handles the MCS certification — choosing an MCS-certified installer like Greentech ensures you qualify automatically.
Maximising Export Income
Pair solar with a battery to export during peak tariff periods (4-7pm) when rates are highest. Time-of-use tariffs like Octopus Flux and Agile reward strategic exporting. A well-managed system can earn £150-£300/year from exports alone.
