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 […]
Read articleChecking bypass diodes: Part 2
In the previous post on checking bypass diodes in solar panels, I described in detail which faults could occur at the bypass diodes and how to detect missing diodes. Another problem that could arise, especially after instances of overvoltage, is a short circuit via the bypass diodes. This post focuses on this fault and the […]
