The revised Feed-in Tariff rate for smaller installations comes into effect today, with the government facing legal action later this week.
Industry has warned that thousands of jobs are now at risk, the most dramatic example of which has been Carillion issuing redundancy notices to 1,500 of its workers and citing the FiT cuts as the reason.
The court case against the government will be heard on Thursday, 15 December, when the combined actions of SolarCentury, HomeSun and Friends of the Earth are heard.
The aim of the three main parties is to ask for permission to challenge the government’s decision to cut payments.
Friends of the Earth states that up to 29,000 jobs are at risk, which would lose the Treasury up to £230 million a year in tax income, with many schemes already cancelled.
Andy Atkins, Friends of the Earth executive director, said: “These Government cuts will cast a huge shadow over our thriving solar industry and pull the plug on thousands of jobs.
“We don’t oppose modest payment cuts in line with falling installation costs – but the size and speed of these proposals will decimate an industry that could play a key role in weaning the nation off of expensive fossil fuels.
“Ministers must think again and give their support to an industry that could and should be at the cutting edge of a clean energy revolution.”
