Data estimating the floor area of non-domestic properties, from which commercial roof space can be inferred, is available on www.gov.uk here: https://www.gov.uk/government/statistics/non-domestic-national-energy-efficiency-data-framework-nd-need-2020. However, not all rooves are suitable for solar panels due to shading, orientation, and location.

Solar is key to the Government’s strategy to decarbonise energy. The Government is supporting commercial rooftop solar deployment through capital allowances for spend on solar panels, exempting solar and storage used on site from business rates from 1 April 2022 until 31 March 2035, and changes to energy performance standards for non-domestic buildings.
