Britain's energy ministry said it will on Monday launch a review of state subsidies for solar power installations, the second change to the scheme since it started in April 2010.
Energy Minister Greg Barker is scheduled to publish details of a consultation into altering the so-called feed-in tariffs (FITs) in Parliament at around 10 a.m. on Monday.
"We'll be publishing a full consultation on changes to the solar PV (photovoltaic) tariff changes in Parliament on Monday," a spokeswoman for the Department of Energy and Climate Change said.
The ministry also said leaked consultation documents on the Internet, which proposed a 50 percent cut, were inaccurate.
The minister is widely expected to suggest slashing state aid for solar plants, after he hinted at a tariff reduction in a speech delivered at a conference on Thursday, saying costs for solar modules had fallen 70 percent in two years.
