In total over a period of a few years a reporter's firm of consulting engineers assessed approximately 25,000 domestic roofs to check their adequacy for supporting PV panels. These were carried out on the basis of existing roof information provided by the installer.
Of those investigated, between 15 and 20% were found to be structurally inadequate. In some of these instances they recommended strengthening works such as propping purlins, doubling up on rafters and other measures.
