This Code of Practice sets out the requirements for the design, specification, installation, commissioning, operation, and maintenance of grid-connected solar photovoltaic (PV) systems. Important updates have been made to this second edition, including new legislation and standards within the evolving landscape of solar PV systems. Topics include systems design, approval, installation and operation. Key safety requirements in the protection and earthing of PV systems mounted on both in buildings and on the ground is covered in detail. It also contains requirements for commissioning, monitoring and maintenance throughout the lifetime of an installation. 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. It is an invaluable resource for technicians and supervisors who may be responsible for overseeing solar PV systems deployment.
