Find the real fault
You don't need to know what's wrong to get it looked at. Describe what's happening and an independent technician will take it from there.
Solar PV faults are not always obvious. You might notice lower generation, an occasional inverter warning, unexplained shutdowns or simply that the figures no longer match what you expect. Replacing parts without understanding the cause can waste time and money.
Fault finding is designed to narrow down the problem methodically. Independent technicians use the information available from the system, the symptoms you have noticed and relevant inspection and testing to identify the likely cause. From there, they can explain what needs attention and whether a repair is worthwhile.
Diagnosis is particularly useful where the symptom could have several possible causes or where a previous quick check has not resolved the problem.
Technicians investigate unexplained reductions in generation and look at whether the cause is a system fault or another factor affecting performance.
Problems that appear and disappear can be difficult to trace. Details about when the fault occurs can help narrow the investigation.
Where generation has stopped, the technician works through the relevant parts of the installation to establish where the problem lies.
An inverter message can provide a useful starting point, but further investigation may be needed to determine the underlying cause.
Where displayed generation appears unusual, a technician can help determine whether there is evidence of a system problem or an issue with the information being reported.
Fault-finding requirements differ between systems. Complexity, accessibility and the nature of an intermittent problem can all affect the work involved.
Say whether the problem is there all the time or comes and goes, and whether it seems linked to time of day or weather.
If you have monitoring or meter readings, comparing a recent month with the same month last year can be revealing.
Mention any earlier repairs, replacement parts or visits, especially if the problem came back afterwards.
Error messages, warning lights or anything that looks different. You don't need to know what it means.
You don't need to diagnose the system yourself. Tell us the symptoms and the technician will start there.
Free — no obligations
The technician asks what changed, when it started and whether the problem is constant or intermittent.
Relevant inverter information, monitoring data and visible system condition can help focus the investigation.
The technician carries out appropriate checks on the relevant parts of the installation.
The technician sets out what appears to be causing the problem and the sensible next step.
If remedial work is needed, the technician explains the proposed work before proceeding.
