The Department of Energy & Climate Change (DECC) appointed Parsons Brinckerhoff (PB) to update the costs of solar PV used in DECC’s model for the UK Feed-In Tariff (FIT).
PB used a number of different sources to update the PV cost data. These were:
market intelligence received from DECC (both formal consultation responses and data received through other channels)
quotes for PV installations sourced from a number of different PV companies
consultation with experts from the PV industry, including installers, manufacturers, and industry analysts
analysis of domestic and global trends in PV markets, both on the supply and the demand side making use where possible of existing expert analysis on the solar sector
