Most UK solar panel fires caused by DC isolators: Report

The UK government released a report on Tuesday on why fires had occurred at 80 solar panel locations throughout the country.

By Jack Unwin

The UK government released a report on Tuesday on why fires had occurred at 80 solar panel locations throughout the country, in response to media coverage linking photovoltaic power systems (PV) with fires.

Delve into the renewable energy prospects for Morocco

In its new low greenhouse gas (GHG) emission strategy to 2050, submitted to the United Nations (UN), the Ministry of Energy Transition and Sustainable Development (MEM) of Morocco suggested to raise the share of renewable capacity in the country’s total power installed capacity mix to 80%.   Morocco currently aims to increase the share of renewables in total power capacity to 52% by 2030. The new strategy plans to increase the share of renewable capacity to 70% by 2040 and 80% by 2050.  GlobalData’s expert analysis delves into the current state and potential growth of the renewable energy market in Morocco. We cover: 
  • The 2020 target compared to what was achieved 
  • The 2030 target and current progress 
  • Energy strategy to 2050 
  • Green hydrogen 
  • Predictions for the way forward

The report, “Fire and Solar PV Systems, Investigations and Evidence”, was prepared in May 2018 and released by the Department for Business, Energy & Industrial Strategy (DBEIS).

Of the 80 solar panel fire incidents investigated the study found that 58 were directly caused by the PV system, with 22 of those leading to serious fires and 27 localised fires. A further 16 involved PVs but were not directly caused by them, of which 15 led to serious fires. In total, 38 incidents were serious fires, 33 were localised fires and nine thermal events. Just six of the incidents took place at solar farms, with the other 74 taking place in buildings.

It was found that direct current (DC) isolators presented the greatest fire risk as the probable cause of 26 of the 80 fires, which the report said were due to poorly designed and installed isolators. DC connectors were the second major fire risk, the cause of five probable and seven possible fires.

The report identifies the most likely cause of fire as electrical arcing, where electricity flows through an air gap through ionised gas molecules and become hot enough to cause combustion. In total, these incidents have led to 13 injuries, including three fatalities.

In the introduction to the report, the authors note that there is little information on PV fires. The data published by the government cannot specify whether fires were caused by PV systems, and some incidents may have not been reported due to being contained by the owners of the systems.

The authors wrote that they hope the report will “feed the data and conclusions into industry standards and the National Occupational Guidance system, which is used to disseminate information to the fire and rescue services.”
