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.

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.

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:

How is a solar PV system commissioned?

The solar PV system shall be commissioned according to a documented procedure to ensure that the system is safe, has been installed in accordance with the requirements of this standard and the manufacturers' requirements, and is operating correctly in accordance with the system design. Practice except 16.4.

Who should check the roof structure of a solar PV system?

5.9.4 The MCS Contractor shall ensure that the roof structure is checked by a suitably competent person to ensure it can withstand the loads imposed by the solar PV system. 5.9.5 For the typical roof structure types shown in Table 1, the calculation methodologies given should be used. qualified structural engineer shall be consulted.

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.
