When the cause isn't obvious
Something's wrong, but you can't tell what. That's exactly what fault finding is for.
Knowing that your solar system is underperforming is only half the answer. The question that matters is why. Lost generation can come from the panels, connections, cabling, the inverter or something else in the installation, and replacing the wrong part wastes both time and money.
Fault finding is for situations where the cause is not obvious. The technician starts with what you have noticed, checks the relevant parts of the system and narrows the problem down step by step before recommending any repair.
Diagnosis is most useful when the symptoms are vague, come and go, or have no visible cause.
A noticeable change compared with your system's normal performance, when the weather does not explain it.
Intermittent problems need a structured approach so conclusions are not drawn from a single moment.
A system message is a clue rather than an answer, and it needs checking against the rest of the installation.
If the panels came with your house, diagnosis can establish what is working and what needs attention.
The time needed depends on the symptoms, how accessible the system is, how it was designed and whether the fault is present all the time or only now and then.
