The firms are seeking more than £130m in damages from the UK government over changes to feed in tariffs in 2011. The government plans to appeal against Mr Justice Coulson’s decision. The judge said the amount of compensation “will ultimately depend on the facts”. “As a matter of general principle, the claimants have demonstrated an entitlement to damages,” he said.

The Department of Energy and Climate Change (DECC) said it will appeal against the ruling. “We are unhappy about this judgement and will be appealing against it,” a DECC spokesperson said. “We believed we were proposing lawful changes to subsidies, which would protect consumers from rising bills at a time when windfall profits meant the industry was booming. “Solar is a huge success in the UK, worth £2.2bn a year, thanks to government support, and the tariff changes that protected consumers from a £50-a-year bill rise by 2020 haven’t changed that success.”
