“Techfor did not pressurise me in any way and patiently took their time in answering my many queries. I was very pleased I chose them as they proved to be very professional and efficient in everything they did whether this was in their technical knowledge, administration or installation. Overall a very good experience.” Tim, Guildford.


The Feed In Tariff and the Smart Export Guarantee

pvmodule_img1The Feed in Tariff is no longer available and has been replaced by the Smart Export Guarantee (SEG). The SEG requires the large licensed energy suppliers to provide at least one export tariff to Solar PV generators generating a maximum of 5MW. Smaller energy suppliers can take part on a voluntary basis.


The large energy suppliers will need to provide the SEG to customers by 1 January 2020, but at the time of writing this article there are already energy suppliers such as Octopus and Bulb offering export tariffs to their customers.



Battery Storage and the SEG


Some battery storage systems such as the Tesla Powerwall v2.0 are able to export stored electricity, for example during the peak time, to the grid and import off-peak electricity during the off-peak period. Currently, it is up to the energy suppliers such as Octopus and Bulb to offer the SEG to customers exporting battery storage electricity to the grid.


To benefit from the SEG you will need to satisfy the following criteria:


1. Not receiving the FIT

2. Your renewable generation should not be generating more than 5MW of electricity

3. Have a half-hourly export reading grid meter

4. Your installation must be MCS certified


At the time of writing the above, the SEG process is at its infancy and as this area of the market matures we will provide more information. In the meantime, if you need further information on tariff comparisons and additional information please visit the Solar Trade Organisation

* PV Tariff level as detailed below:

Higher tariff rate will be applied if an EPC of level D or above is achieved before commissioning

Middle tariff rate will be applied if an EPC of level D or above is achieved before commissioning but the generator owns 25 or more installations

Lower tariff rate will be applied if an EPC of level D or above is achieved after the commissioning

All tariff rates are in pence per kilowatt hour at 2018/19 values
