What Is The Smart Export Guarantee?
The Smart Export Guarantee (SEG) allows you to get paid for surplus electricity generated by your solar panels and exported back to the grid.
Payments are made by participating energy suppliers, with rates varying between providers. To apply, you’ll typically need an MCS-certified solar PV system and a compatible smart meter.
Compare suppliers, submit your application and start earning for the energy you don’t use.

Want to get more from your solar and battery?
If your system includes battery storage, switching to a time-of-use tariff could help you make better use of your system. You may be able to charge your battery when electricity is cheaper and then use your stored energy during more expensive peak periods.
