For those of us who can’t get enough of solar troubleshooting info, I present to you your “SolarFix”, where I’m highlighting what the larger solar community is able to share when it comes to troubleshooting and maintenance of PV installations.
From a post by Energy Support Services:
Every season presents its own set of opportunities and challenges for solar energy systems, but the elevated temperatures of summer can be particularly tricky. One common issue is overheated breakers, which can lead to system failures. This case study conducted by Energy Support Services (ESS) explores a scenario where overheated breakers impacted multiple project stakeholders, and how innovative solutions were implemented to address the problem.
Great little case study. I’ve known similar situations with direct sun on an AC combiner box to be dealt with via some kind of extra sun cover. If you can interrupt the sun’s radiance before it ever hits the box, you’ve probably already fixed your intermittent breaker-tripping issues. The other solution is spacing your breakers farther apart, but often that’s not practical, depending on how the system was originally built.
If you’ve seen something that should be highlighted in SolarFix, or would like to submit a guest post, let me know!
