MPs on the Energy and Climate Change Committee and the Environmental Audit Committee joined forces to take evidence on solar power feed-in tariffs on 29 November 2011.
Under the "feed-in tariffs" programme, people in Britain with solar panels are paid for the electricity they generate.
The government plans to pay a reduced rate of 21p per kilowatt-hour, down from the current 43p, to anyone who installs their solar panels after 12 December.
The move has been criticised by Environmental charity Friends of the Earth and business group the CBI.
