UK Solar Installations Reach Highest Monthly Level Since 2012
May,2026 :Households across the UK are installing solar panels at the fastest monthly rate seen in more than a decade, as the government continues its clean power programme and seeks to reduce reliance on unstable fossil fuel markets following the outbreak of the war in Iran.
According to new government data published on 30 April 2026, more than 27,000 solar installations were completed in March 2026. This was the highest monthly total recorded since 2012.
The increase was mainly driven by rooftop solar. Around two-thirds of the new installations were solar panels fitted on homes.
The figures also show that the UK passed a major milestone in March 2026, with total solar installations rising above two million for the first time. This includes installations on both rooftops and solar farms.
Over the past year, solar capacity across the UK increased by 11.7%, adding 2.3 GW of clean, homegrown electricity to the country’s energy mix.
The government says the growth of domestic renewable power can help protect households and businesses from international gas price shocks.
The rise in solar deployment comes as the government increases support for solar power across homes, schools and communities.
Measures include approval for Springwell Solar Farm, described by the government as the largest power-producing solar farm in UK history.
The government is also supporting the rollout of low-cost “plug-in” solar panels, which can be placed on balconies or outdoor spaces and are expected to become available in shops within months.
Plans are also being advanced to make solar panels standard on new homes in England.
Key Points
More than 27,000 solar installations were completed across the UK in March 2026.
This was the highest monthly solar deployment since 2012.
Around two-thirds of the new installations were rooftop solar panels fitted on homes.
The UK passed two million total solar installations for the first time.
Solar capacity increased by 11.7% over the past year, adding 2.3 GW of clean electricity.
Solar output passed 15 GW for the first time on Britain’s electricity system.
The government is supporting solar growth through homes, schools, communities and new housing.
An extra £100 million is planned for the Social Housing Fund, subject to final approvals.
Solar generation also reached a new record this month. National Energy System Operator data showed solar output passing 15 GW for the first time on Britain’s electricity system.
Energy Secretary Ed Miliband said the figures showed strong progress in the UK’s clean energy mission, with solar installations reaching their highest monthly level in more than a decade and more than two million systems now powering homes across Britain.
He said the government’s clean energy approach was aimed at helping families manage global energy shocks, reduce bills and move Britain away from dependence on fossil fuels.
The government said the latest progress builds on Great British Energy’s solar scheme, with support planned for a further 100 schools and colleges to install rooftop solar panels this year.
Subject to final approvals, the government is also providing an additional £100 million for the Social Housing Fund, which could support up to 57,000 solar installations for households during this financial year.
