6 FAQs about [Inspecting photovoltaic support equipment]
Do solar PV systems need a professional inspection?
nsure provisions are made for a competent person to carry these out, as necessaryAs with other installed technology and appliances (for example, domestic and commercial boilers), all solar PV systems need professional inspection and mainten nce to identify and resolve technical and other pr
How often should a solar PV system be inspected?
In this respect, there are some key solar PV system features that rely on adequate and appropriate electrical testing and inspection being undertaken on a regular basis. IEC 62446 recommends that periodic verification of an existing installation shall be performed.
Why do solar PV systems need periodic electrical testing?
The periodic testing of the electrical cabling and components associated with solar PV systems will ensure the safe operation of the system and reduce the potential fire risk associated with any electrical faults. All solar PV installations require the provision of various documentation and forms to the customer.
Do solar PV systems need electrical testing?
Periodic electrical testing of solar PV systems to identify and confirm continued safe operation and maximum energy output performance can be required as part of product warranties and PV system component guarantees. As the number of rooftop solar installation systems have grown over the years, so have the number of reported incidents of fires.
What documentation do I need for a solar PV installation?
All solar PV installations require the provision of various documentation and forms to the customer. System documentation usually includes system data, installer details, electrical diagrams, operation and maintenance instructions and other information that may be required by certain standards or regulatory bodies.
What is the seaward Guide to solar PV Testing?
The Seaward Guide to Solar PV Testing seeks to offer guidance to PV system technicians and engineers to identify exactly what electrical testing is needed to fulfil their obligations to the customer and also to satisfy the various industry standards (including NABCEP) and best working practices available.
