outputs and safety levels are achieved. And once in operation, it is important to ensure that the long-term performance of the system is not compromised by sub-standard installation or poor maintenance. In this respect, there are some key solar PV system features that rely on adequate and appropriate electrical testing and inspection being undertaken on a regular basis.

As such, this standard not only specifies the minimum electrical testing and inspection requirements but equally importantly how the inspection and test results are documented and supplied to the consumer after installation. Where appropriate, the results and

include a list of any faults and recommendations for repairs or improvements (such as upgrading a system to meet current standards).


effeCtive grounding


As with all electrical equipment, solar panels and their racking systems must be grounded to mitigate potential electric shocks and fire hazards. If the grounding system degrades over time, anyone who comes into contact with a metal piece of the system may receive a
