Government Solar Incentives
Smart Export Guarantee (SEG):
- Following the closure of the FIT scheme, the Smart Export Guarantee (SEG) was introduced on January 1, 2020, as a replacement mechanism to incentivize solar panel owners to export surplus electricity to the grid.
- Under the SEG, energy suppliers with over 150,000 customers are required to offer payments to small-scale renewable energy generators, including solar panel owners, for each kilowatt-hour (kWh) of electricity they export to the grid.
- The rates offered under the SEG vary between energy suppliers and are determined by market forces. This means that participants may need to shop around to find the best SEG tariff for their circumstances.
- Unlike the FIT scheme, which guaranteed payments for all electricity generated, the SEG only compensates participants for the surplus electricity they export to the grid. Participants must have a smart meter installed to accurately measure their export.
Feed-in Tariff (FIT):
- The Feed-in Tariff (FIT) was a government scheme introduced in 2010 to encourage the adoption of renewable energy technologies, including solar PV systems, by providing financial incentives to homeowners and businesses.
- Under the FIT scheme, participants were paid for the electricity generated by their solar panels, regardless of whether they consumed it on-site or exported it to the grid. This payment was made in addition to any savings on electricity bills.
- The FIT rates were set by the government and guaranteed for a certain period (typically 20-25 years), providing participants with a stable and predictable income stream.
- However, the FIT scheme closed to new applications on March 31, 2019, meaning that homeowners who installed solar panels after this date are not eligible to receive FIT payments.
In summary, while the Feed-in Tariff (FIT) provided guaranteed payments for all electricity generated by solar panels, the Smart Export Guarantee (SEG) offers payments specifically for surplus electricity exported to the grid. The SEG is the current mechanism for incentivizing solar panel owners to contribute to the UK’s renewable energy goals.
