How short-circuiting a solar array can help with faultfinding

I have already described a number of methods here in the blog that you can use to discover and pinpoint almost any fault that can occur in a photovoltaic system – or so I thought. But then I came across a “tough cookie”, where it took several attempts to locate the cause of the reduced […]

Locating broken wires in solar systems

Here in our blog, we have already described many ways of speeding up fault location in photovoltaic systems. But there is one rather mundane fault that we haven’t yet discussed: a break in the wiring on the DC side of a module string. This kind of fault is relatively easy to find. If the string […]
