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.
