New government data published today shows that more than 27,000 solar installations were completed in March 2026 – the highest monthly total since 2012 – bringing the total number of solar installations across the UK to more than two million for the first time.
Solar capacity increased by 11.7% over the past year, adding 2.3 GW of clean, homegrown electricity to Britain’s energy mix.
This growth means British renewable power is being generated domestically, with the record growth coming as the UK Government begins the rollout of ‘plug-in’ solar panels, which will be available in shops within months.
This month also saw a new record for solar generation, with National Energy System Operator data showing solar output passing 15 GW for the first time on Britain’s electricity system.
Energy Secretary Ed Miliband said:
“The numbers speak for themselves – the highest monthly installation of solar in over a decade, rising capacity and more than 2 million solar installations now powering homes across Britain.
“This is our clean energy mission in action – helping families weather global energy shocks, bringing bills down, and getting Britain off the fossil fuel rollercoaster.
“These installations build on the success of Great British Energy’s solar scheme, with the government backing the company to support a further 100 schools and colleges with rooftop solar installations this year.
“In addition, subject to final approvals, the government is providing an extra £100 million for the Social Housing Fund, helping deliver up to 57,000 solar installations for households during this financial year.”
