Ecotricity has acquired the home rooftop solar business of SunEdison.
Before exiting the UK, SunEdison had built a portfolio of nearly a thousand rooftop solar installations, a product known as the Energy Saver Plan.
The news comes on the day SunEdison Inc. filed for bankruptcy in the U.S.
Ecotricity founder Dale Vince said: "This is an exciting and important step for Ecotricity. As a company, we want to help more people generate their own power at home.
"The government’s cuts to the feed-in tariff, and its broader attack on the renewables industry, have caused a significant problem for companies like SunEdison: we have seen some go bust and others quit the UK market as a result, losing a lot of jobs as a result.
"This is our first step into the domestic solar market, and as the price of the technology continues to fall, we’re confident that it’s only a matter of time before we can resume the work SunEdison started and help more homes take advantage of solar power."
Ecotricity, who now supply approaching 200,000 customers from a fleet of wind and sun parks, last made an acquisition in 2014 when they rescued small windmill company Evance from administration – uniting Evance with other supply chain companies, Ecotricity formed a new small windmill company called Britwind.
Dale said: "We see a big future for renewable technology of this scale in Britain – small wind and rooftop solar will allow more people to generate their own power at home, decentralising the energy sector and putting power in the hands of the people."
