Planning
In general the installation of solar panels, as far as planning permission is concerned, is reasonably straight-forward with most local authorities regarding the panels in a similar vein as to flush fitting roof-light windows, where planning permission may not be required.
However it is prudent to seek the opinion of the local authority on planning matters prior to starting work on the solar installation. Requirements vary from one authority to the next both with planning permission and building control procedures.
Site preparation/portability
In addition to ensuring that the panels are sited in the correct direction and away from sources of shade, particular attention should be paid to site access and the safe installation of the panels. When working at height care should be take to ensure that the required safety equipment is available and correctly used.
