Tesco Stores
FAMILY OF INCORRECTLY TORQUED DC CONNECTORS
11 Sites Across the UK
Client: Tesco Stores
Six monthly preventative maintenance check of Tesco Store’s 3.3MW (9,888 panel) solar PV system.
Using Safetyculture inspection software, Helios inspected and tested all elements required of this installation and identified faults including: missing and incorrectly torqued mid and end clamps (which keeps the panels in place) slipped panels, broken panels, incorrectly torqued DC connectors (the most common cause of rooftop fires), incorrectly installed ballast, incorrectly installed wiring, threaded bolts, underperforming strings and panel soiling issues. Identifying these issues is not only important for performance of the system, but also for safety.

This is one reason why you should choose an alternative O&M specialist, other than your original installer, to check your installation. Otherwise it’s a bit like asking your installer to check their own homework for faults!
Helios were instrumental in developing the UK’s first rooftop PV maintenance guidelines and are the only UKO&M company to be liaising with UK insurers in developing a Joint Code of Practice that will ensure that all testing, inspection and maintenance that is carried out on your solar PV system, will be in line with the latest UK solar industry testing and inspection guidelines to ensure that any system faults or improvements will be brought to your attention.
If your system has not been checked since installation, it’s time to ensure your system is working safely and efficiently. Our expert team will advise on any maintenance requirements, faults detected or improvements needed with an in-depth report. You can trust Helios, the UK’s leading solar panel cleaning & maintenance company to take care of your solar PV system.
