Code of Practice for Grid-connected Solar Photovoltaic Systems (IET Codes and Guidance)

This Code of Practice sets out the requirements for the design, specification, installation, commissioning, operation, and maintenance of grid-connected solar photovoltaic (PV) systems.

Key safety considerations in the protection and earthing of PV systems mounted on buildings and on the ground is covered in detail. It also contains requirements for commissioning, monitoring and maintenance throughout the lifetime of an installation. It is an invaluable resource for technicians and supervisors who may be responsible for overseeing solar PV systems deployment.

This second edition provides updated information to ensure that a solar PV system is designed, competently installed and safe to operate in compliance with current national and international standards - including alignment to BS 7671:2018+A2:2022 and other relevant industry standards.
