How to install photovoltaic panels on a rooftop?

The rooftop installation of photovoltaic panels can be accomplished using three mounting methods: independent support, enclosed attachment, and forced cooling. However, the enclosed attachment method may lead to temperature concentration and reduced photovoltaic performance.

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 are the different types of PV installation?

There are two main types of PV installation: integrated into the roof surface, often referred to as Building-Integrated Photovoltaic (BIPV) systems or mounted above the existing roof covering, also referred to as stand-off systems.

Can a PV system be electrically installed?

Guidance exists for electrical installation of PV systems[15, 16, 17] but there is little equivalent guidance for mechanical installation.

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.

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.
