The following renewable energy installations are eligible for the smart export guarantee:
- solar PV systems, onshore wind, anaerobic digestion, hydro – up to 5MW
- micro-CHP – with an electrical capacity of up to 50kW
Any typical domestic system would be well within these size limits.
The technology and installer used by householders must be certified under the Microgeneration Certification Scheme (MCS) or equivalent. Energy suppliers may ask you to provide a MCS certificate to prove your installation meets this standard.
You will also need a registered smart meter that records your exported electricity, even if you’re not signing up to a smart tariff.
