Do I need to apply for building regulation consent to install a Solar photovoltaic (PV) power supply system?
The electrical installation is covered under the Part P Electrical Regulations. These types of small-scale generators are defined as “Special installations”, irrespective of whether or not they are plugged or wired into the existing electrical systems. You can avoid the need to make a Building Regulation application by using a Government approved Part P certified ‘Competent Person’, who will notify the Local Authority for you (see Part P Electrical Works Guide Note 20 262.92 KB ) The loading imposed upon the existing roof structure and the fixing of the panels requires careful consideration to avoid damage to the roof structure and displacement of the panels in stormy conditions.
