At the end of September, we estimate there were 805,000 domestic solar PV installations1,2. A small proportion of homes may have more than one installation but it is not possible to identify these in the available data.

  1. There were 789,122 domestic solar PV installations in Great Britain registered on the Central FiT Register at the end of September 2018, as published here: https://www.gov.uk/government/statistical-data-sets/sub-regional-feed-in-tariffs-confirmed-on-the-cfr-statistics
  2. There were 17,267 sub 4 kW solar installations in Northern Ireland, registered for the NI Renewables Obligation as at the end of September 2018. It is estimated around 90% of these would be installed on homes.
