What are the installation requirements for a PV array?

Installation requirements are also critically dependent on compliance with the IEC 60364 series (see Clause 4). PV arrays of less than 100 W and less than 35 V DC open circuit voltage at STC are not covered by this document. PV arrays in grid connected systems connected to medium or high voltage systems are not covered in this document.

Are all PV products covered by IEC61730 'photovoltaic (PV) module safety qualification?

In future it is expected that all PV products will increasingly be covered by International standard IEC61730: 2004 ‘Photovoltaic (PV) module safety qualification’.

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 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.

What parts of a PV array are covered?

The scope includes all parts of the PV array up to but not including energy storage devices, power conversion equipment or loads. An exception is that provisions relating to power conversion equipment are covered only where DC safety issues are involved.

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.
