6 FAQs about [Photovoltaic power inverter safety regulations]

How to minimise fire risk from solar PV systems?

The solar industry welcomes clarity on how to minimise fire risk from solar PV systems, which in absolute terms is extremely low. “The core way to mitigate any risk is to ensure the highest possible quality in the design, installation, operation, and maintenance of solar systems.

What are the risks of installing a solar PV system?

The installer is also faced with the dangers of handling potentially large and heavy equipment at height as well as ensuring that the installation of a solar PV system does not have a negative impact on the strength and integrity of the buildings structure (often a roof) where the system is to be mounted. All articles

What are the requirements for photovoltaic (PV) generators?

Requirements for Photovoltaic (PV) Generators (currently in development by IEC TC 82) – will set out general installation and safety requirements for the PV equipment. The Scope of Section 712 in BS 7671:2008 includes PV power supply systems including systems with a.c. modules but, currently, excludes any form of battery storage.

What are the IEC standards for photovoltaic systems?

The IEC also manages global conformity assessment systems that certify whether equipment, systems, or components conform to its international standards. In 2016 and 2020, IEC published two key associated standards: BS EN IEC 62446-1:2016 Photovoltaic (PV) systems – Requirements for testing, documentation and maintenance.

Do solar photovoltaic systems cause fires?

Request an accessible format. This 3-year study by the BRE (Building Research Establishment) explored fires involving solar photovoltaic (PV) systems. The study includes: The incidence of such fires is very low, but the study makes a number of recommendations to reduce risks.

Are solar PV installations notifiable?

To clarify, what is certain is that nearly all domestic electrical work is notifiable under Part P of the Building Regulations (see below) and a solar PV installation is nearly always notifiable electrical work.
