The panels were blown away and scattered across the road below. The residents revealed that Hau Chi House and Hau Lim House, two residential buildings in the estate, suffered significant damage to their solar
In 2021, Storm Arwen wreaked havoc at a solar farm near Wolviston, smashing hundreds of glass solar panels and damaging rows and rows of photovoltaics. 1 In extreme weather, solar panels can operate as lifting surfaces making the panels vulnerable to being blown away, so it’s important that these are securely tethered.
“The problem is not only that some panels are blown away, but that those that have not been blown away (yet) are suffering mechanical fatigue in the anchor joints, weakening them and increasing the probability that they will start to be blown away en masse in the future,” said Asier Ukar, senior consultant and managing director of PI Berlin S.L.
The module manufacturer approved the design, but the tracker is not specifically named in the installation manual. The EPC contractor said that only a few modules have been blown away, but the reality is that the entire plant is theoretically exposed to potential wind damage.
Micro-cracking, or micro-fractures, can occur in solar panels when panels are subject to strong wind forces. The silicon used is very thin and when it expands and contracts, or when it’s damaged by wind or falling debris, it can crack, making the panel less efficient at absorbing light and storing energy.
Dust and water may also travel into the cracks, further harming the effectiveness of the panels. There is also an issue with the longevity of solar panels. Solar power installations should be lasting 40-50 years, but due to weather damage and issues with materials and construction, they are currently only lasting for 20.
Solar panel systems are now an increasingly popular choice. According to the Microgeneration Certification Scheme there were 130,596 solar systems mounted on UK rooftops in 2022.
