Britain’s 2025 solar power generation surpasses 2024’s total

Britain’s solar industry has reached a new milestone in 2025, generating more electricity so far this year than during the whole of 2024. This achievement highlights both the rapid expansion of large-scale projects and the steady growth in residential and commercial rooftop installations.

Record-breaking growth in solar capacity

The first half of 2025 saw more than 2GW of new capacity added, almost matching the entire volume installed in the previous year, which itself was a record. A major contributor this year was the completion of Cleve Hill Solar Park in Kent, the country’s first nationally significant infrastructure project for solar. At 373MW, it stands as the UK’s largest solar farm, reflecting the growing trend towards utility-scale developments.

Ground-mounted projects remain dominant, accounting for around 70% of the year’s additions, while commercial and residential rooftops have also seen robust growth. This strong performance has been supported by a combination of government incentives and market confidence following new energy policies.

Rooftop installations and local opportunities

Beyond large-scale farms, rooftop installations continue to play an important role. Businesses and homeowners are turning to solar panels as energy costs remain high and sustainability goals gather pace. Local demand is evident in areas such as Worcester. Local installers, such as //gsmlimited.com/services/solar-panels/worcester/, provide solar panels Worcester.

With further projects under construction and record numbers of planning submissions already in the pipeline, Britain looks set to close 2025 with its strongest solar growth in more than a decade. This momentum positions solar as a cornerstone of the UK’s clean energy strategy for the years ahead.
