During the inspection it became clear that there were issues with some of the connections within the existing infrastructure.  NWT’s engineers are fully qualified electricians and have strong backgrounds in electrical contracting.

In this case, a family of mice had managed to gain access to one of the sealed areas, probably drawn to the heat around the cables.  They made bedding out of operation manuals stored in the same building and chewed through the sheathing of the internal wires.  Once we discovered their activity, one mouse was electrocuted but the rest escaped.

The mice had managed to gain access to the cabinet through some gaps in the seals on the left-hand side, before making their home. Over time they managed to cause significant damage to several of the internal wires, affecting the electricity supply at the building and interrupting the operation of the solar PV system.

With the income from solar PV installations payable over a fixed period, losses in revenue from system downtime can’t be recouped later.  It was good news for the client when NWT Energy removed the rodents and their debris and fixed the damaged wiring.  This returned the system to its operating potential and ensured the client was back on track with their investment.  NWT Energy strongly recommends the installation of a PV monitoring system, which will raise alerts to any issues, so that they can be rectified quickly and your investment is protected.
