Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what steps his Department is taking to ensure that Ofgem is able to collate accurate data on the installation of solar power units.

The Solar photovoltaics deployment report, published on the gov.uk website, provides information on solar photovoltaic capacity in the United Kingdom. It currently includes solar installations reported in BEIS' major power producers survey, the Renewable Energy Planning Database, the Microgeneration Certification Scheme database, and those subsidised by the Renewables Obligation, Feed-in Tariff, and Contracts for Difference. It does not currently include unsubsidised solar installations below 1MW capacity that are not registered on the Microgeneration Certification Scheme database, although we are reviewing data sources to improve coverage.
