UK government data shows that 621MW of new solar PV capacity was added in the first half of 2025, bringing total installed capacity to 19GW. These provisional statistics indicate the UK is on track to exceed its target of adding over 1GW in 2025. However, deployment must accelerate significantly to meet the 2030 capacity goal of 45-47GW. The Department for Energy Security and Net Zero (DESNZ) statistics are provisional and subject to revision with new data, as the department reviews data sources to improve accuracy.

In June 2025, 88MW of new solar installations were added, lower than the 160MW recorded in the same period of 2024, but significant growth is anticipated. Developer Quinbrook announced in July 2025 that its 373MW Cleve Hill solar park had commenced grid connection, feeding 100% of its output into the grid, making it the UK's largest solar project to date. Concurrently, the government approved major projects meeting nationally significant infrastructure criteria, including the 180MW Byers Gill, 400MW East Yorkshire, 500MW Heckington Fen, and 138MW Oaklands solar farms, further advancing large-scale development.

To achieve the 2030 target, the UK government plans to implement solar roadmap measures. These include launching the seventh Contracts for Difference (CfD) auction round in August 2025, strengthening energy efficiency requirements for new buildings, and reforming planning and grid connection processes. Additionally, regulatory amendments to permit balcony and rooftop solar panel installations are under evaluation, alongside support for deploying solar canopies in car parks. These initiatives aim to accelerate the nationwide transition to clean energy.
