Recently, according to the latest statistics released by the Department for Energy Security and Net Zero Emissions (DESNZ), by February 2025, the total installed capacity of photovoltaic power in the UK has exceeded the threshold of 18GW, which is equivalent to 1.735 million photovoltaic systems contributing clean energy to the UK's green transformation. Compared with the same period last year, this figure has increased by 6.8%, and the newly installed capacity has reached 1.1GW. This trend fully demonstrates the UK's continued progress in the field of renewable energy.
From the analysis of the installed capacity structure, the UK photovoltaic market presents the characteristics of a large number of household photovoltaic systems and a large scale of ground power stations. Although the number of household photovoltaic systems accounts for 73%, its installed capacity only accounts for 30% of the national total. In February 2025, the newly installed capacity of residential projects was 58MW, maintaining a steady growth trend. At the same time, as the dominant force in the UK's photovoltaic installation, ground power stations have contributed about 7.71GW of installed capacity, accounting for 43% of the total installed capacity. If "uncertified" projects are taken into consideration, the actual proportion of ground power stations may be as high as 55%.
Data shows that the average installation cost of a household photovoltaic system has dropped from £9,238 in January 2024 to £7,561 in December, with an average price of £8,198 for the whole year. This price advantage, coupled with policy support, has led to more than 200,000 household photovoltaic installations from January 2024 to January 2025, while also driving the installation of 22,667 household energy storage systems.
It is particularly noteworthy that of the 2.3GW of new installations in 2024, residential and commercial rooftop projects each accounted for 20%, indicating that distributed photovoltaics have strong development potential. With the continued decline in costs and the improvement of energy storage facilities, the UK photovoltaic industry is ushering in new development opportunities.
