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.
Exported power must be metered using a meter capable of reading exports on a half hourly basis, even if half hourly readings are not required for the tariff. Meters must also be registered for settlement.
