Specialist Energy was contacted in March 2017 after a system owned by an electrical engineer was showing poor performance. He had measured the string voltages and one of the strings was reading about 15% lower than another identical string.

Using the clients scaffold tower we were able to access the faulty panel. Using a thermal camera we measured the comparative temperatures of the panels, and found one which was significantly hotter than the rest of them. This is pretty unsual - but unless all 3 bypass diodes had failed at once there was only really one explanation. It turned out the panel had been completely missed out of the array by the installer and was simply short circuited. Not a dangerous situation - but one which would have lead to a significant financial impact over the years.

The problem was remedied within 8 hours...
