Recommendations for fire safety with photovoltaic panel installations – RC62 Revision – What you need to know.

On the 1st December 2021, a draft version of RC62 was issued to the UK solar industry for peer review.

The draft had already been reviewed by representatives of the UK Insurance industry.

The peer review process finishes on the 19th January 2022 and the final document will then be published as a pre-cursor to a Joint Code of Practice between the UK Solar & Insurance industries that will be published later in 2022.

Below are a few key points to consider.

What is it?

Essentially, it’s a guide that references how all solar PV systems should be designed, installed, commissioned, maintained and de-commissioned to ensure that the correct processes are followed so that your solar PV system safely and efficiently generates electricity.

The guide references many existing regulations that should already be being followed.

Unfortunately, some installers haven’t been overly diligent in ensuring that their installations meet all the required regulations.


Who’s it by?

The process has been led by Robert Harley, Director of Helios Solar Operations & Maintenance Ltd, with the document having been written by James Hoare CEng FIET FEI, arguably the UK’s most senior PV technical expert.

The writing of the document has been jointly funded by the Fire Protection Association and the UK’s foremost renewable energy standards organisation, the MCS.

How will it affect me?

If your original installer is still trading and they are already complying with the correct quality standards then you shouldn’t be affected at all.

However, if you, or they, have or are not complying with the correct design, installation and maintenance guidelines then in the event of an insurance claim from a fire caused by your solar PV system, you may not have insurance cover.

This has already resulted in uninsured losses of over £800,000 in the past (farmhouse in Devon).


What do I need to do?

You’ll already know if you have your solar PV system tested and inspected annually and whether you get a comprehensive report with any recommendations.

Helios Solar Operations & Maintenance Ltd have been instrumental in the development of the UK’s testing and inspection guidelines that have been recommended by the trade body Solar Energy UK and the MCS and we can provide you with these services together with a comprehensive report on the current condition of your solar PV system from both a safety and performance perspective.

Helios also carry out additional series resistance testing that isn’t in current guidelines but will be a requirement of the new Joint Code of Practice. Series resistance testing allows Helios to identify potential hazards before they pose a fire risk.
