The average installation costs of small-scale solar photovoltaic systems in the United Kingdom have fluctuated in the period of consideration. From April 2021 onwards, the cost of solar installations in the 0-4KW band began to increase, outpacing cost increases in the 4-10KW band. In the period of consideration, prices peaked at British pounds per kilowatt installed for the 0-4 kW band in January 2022.

Installations

In the financial year of April 2018 to March 2019, there were *installations in the 0-4kW band. This was an increase of ** percent when compared to the same period the previous year. The highest number of installations occurred in March 2019, at . This peak was mainly due to the closure of the Feed-in Tariff scheme. Between April 2019 and March 2020, the number of installations declined by ** percent compared to the previous year.

Feed-in-Tariff

The Feed-in Tariff (FIT) scheme was introduced in April 2010. It was a government program designed to promote the uptake of low-carbon and renewable electricity generation technologies. Since its introduction, the capacity of the FIT scheme for solar PV was highest in the first quarter of 2012 at ** kW. By October 2020, the total capacity of Solar PV installations under the FIT scheme reached roughly *** gigawatts. The scheme ended in April 2019.
