Testing and Maintenance of Solar PV Systems

From: £295.00


More and more we find ourselves working in homes and businesses which have PV systems installed, whether working directly on the systems or in other areas, there are specific and unique hazards when maintaining buildings with Solar PV installed.

PV Installations operate at very high DC voltage at high currents and they cannot easily be switched off or isolated, there are also dual AC supplies into the electrical distribution system. Maintenance staff need to be aware of potential risks and the implications of not understanding what they may be dealing with.

Solar PV systems are extremely reliable but like most technologies, they still benefit from periodic maintenance to check efficiency and ensure maximum output. With regular basic maintenance and testing you are able to ensure that your clients system is performing to 100% of its capabilities ensuring maximum returns from their investment.

This course will give your operatives the skills and knowledge needed to test solar PV systems safely and systematically determine any faults, making sure they don’t put themselves at risk, even if working on other aspects of the building.
