What are solar PV feed-in tariffs?
• A government guaranteed payment for 25 years per kWh of renewable electricity generated.
• Payments are tax free for householders (not for businesses) and increase annually in line with the retail price index.
• There is a price “degression” for new installations as capital costs of installations fall due to the volume of the market.
• The cost of feed-in tariffs is passed to all electricity users and is estimated to add £3 per year to household electricity bills
