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.

The series resistance of a PV string system is the total electrical combined series resistance from the string ends connecting the inverter /optimiser and the module(s). When in darkness the PV cells have a high series resistance and in daylight healthy cells lower to a very low value of about 0.5 Ohms per module, and the connectors, junction boxes, cable all add a low but insignificant resistive value.
