Estimate how much income your exported solar electricity could generate from your annual output, self-consumption and export tariff.
Income from exported electricity only.
The calculator separates electricity used in the home from the surplus sent to the grid.
Enter the expected or measured annual solar output in kilowatt-hours.
Electricity used directly in the home is not exported and therefore does not earn the export tariff.
The remaining exported electricity is multiplied by the rate paid for each kilowatt-hour.
Using 3,800 kWh of annual generation, 40% self-consumption and an export rate of £0.15/kWh:
Your income depends on annual generation, the percentage used at home and the export tariff. Actual results vary by system output, household demand and supplier rate.
The Smart Export Guarantee is the UK framework under which eligible small-scale generators can be paid by participating licensed suppliers for electricity exported to the grid.
Yes, because less electricity is exported. However, self-consumption may still be financially more valuable when the avoided import rate is higher than the export rate.
