Find the Cause of Solar Faults
Stop guessing what is wrong with your solar system. Arrange diagnosis.

When a solar system is not behaving normally, diagnosis should come before replacement. Low output, unexplained shutdowns and warning messages can have several possible causes, and the component that appears to be at fault is not always the source of the problem.
Our solar PV fault-finding service connects you with a technician who narrows down the issue methodically. They start with the symptoms and available system information before investigating relevant components. The aim is to give you a clear diagnosis and a sensible basis for deciding what happens next.

Fault finding can be useful when a system has completely stopped, is producing less than expected or has developed an intermittent issue that has been difficult to pin down.
Technicians investigate systems that have stopped producing electricity to identify where normal operation has been interrupted.
Unexpected performance drops can be investigated using system information, operating behaviour and relevant testing.
Problems that come and go can be challenging. Details about when the fault occurs can help narrow the investigation.
Technicians assess inverter warnings and other system indications to establish whether they point to an equipment or wider installation issue.

Technicians work from the symptoms toward the cause rather than replacing components speculatively.
They explain what the investigation indicates and what action is sensible.
The purpose of diagnosis is to identify a practical way to restore reliable operation where possible.
Not sure what is wrong? That is exactly what fault finding is for. Describe the symptoms and arrange an assessment.
Free — no obligations

We gather information about generation, warnings, monitoring data and recent changes.
The technician assesses the system for visible and operational signs that help narrow the fault.
Relevant checks are used to identify which part of the system requires attention.
The technician explains the findings and recommends the appropriate repair or next step.
