The government's feed-in-tariff system allows homeowners to receive 41.3 pence (0.50) per kilowatt hour generated regardless whether they use the energy or sell it back to the National Grid. People can make about £25 to £30 selling unused energy back to the grid.
The BBC continued that panels that are most commonly installed by homeowners, consist of eight panels which can generate up to 2.5 kW and cost between £10,000 and £12,000 (aprroximately 12,000 to 14,000). After installation, the tariff is paid for 25 years and increased accordingly with the current rate of inflation.
