Photovoltaic channel panel installation specifications and standards

What guidance is there on the performance of PV systems?

The Good Practice Guide provides some guidance on the performance of PV systems in Section 4 of the updated PV Installers Guide. The PV Specialist should model the system using one of the software simulation programmes available, which have a ‘library’ of modules and inverters and can select the sunlight conditions most representative of the site.

Are there any UK standards relating to a PV installation?

While many UK standards apply in general terms, at the time of writing there is still relatively little which specifically relates to a PV installation. However, there are two documents which specifically relate to the installation of these systems that are of particular relevance:

What is a roof mounted photovoltaic system guidance?

The guidance refers only to the mechanical installation of roof mounted integrated and stand-off photovoltaic systems; it provides best practice guidance on installation requirements and does not constitute fixing instructions.

What are the requirements for a PV installation?

Virtually all domestic PV installations will fall under the scope of Part P. Part P requires the relevant Building Control department to be notified and approve the work. There are two routes to comply with the requirements of Part P: Notify the relevant Building Control department before starting the work.

Is mechanical design of a PV array within the scope of this document?

Mechanical design of the PV array is not within the scope of this document. BRE digest 489 ‘Wind loads on roof-based Photovoltaic systems’, and BRE Digest 495 ‘Mechanical Installation of roof-mounted Photovoltaic systems’, give guidance in this area.

How should a PV system be designed & installed?

From the outset, the designer and installer of a PV system must consider the potential hazards carefully, and systematically devise methods to minimise the risks. This will include both mitigating potential hazards present during and after the installation phase.
