Why schedule inspection test & maintenance?

All electrical systems need periodic inspection and test. Solar PV systems are not exempt from this requirement. For PV systems mounted on buildings, the recommended inspection interval will depend on the type and use of the building.

Typical inspection triggers include:

  • An obvious fault has developed
  • Concerns about erratic behaviour or reduced returns
  • Periodic verification / routine maintenance
  • A change in system ownership
  • To safeguard your investment

What's the risk?

In the vast majority of cases, problems won’t occur. Even when they do, the most common problem is reduced system output, undermining your investment returns. Very occasionally however, faults lead to fire or shock risk.

Faults occasionally develop in even the best installed and properly specified PV systems. The most obvious fault is usually an inverter failure, which generally is spotted pretty quickly.  However, a loss of 1 or 2 strings in a larger system can be much more difficult to spot (can go unnoticed for months) and lead to a significant loss in income.

Monitoring and fault alarms

While not an alternative to periodic system verification, an effective remote monitoring and fault reporting system will provide early warning of drops in performance or faults.

Most well designed larger systems should include such a facility. Retrofitting is a practical and effective option where not installed at the outset.
