Pulled two solar panels off one of my arrays, because a few of them have hot junction boxes from bad connections. Replaced those with spares and got the array back fully online (one of them has been bypassed for arc fault warnings that, digging into the junction box, look legit).

Then I replaced all the fancy, spring loaded, "replace the back of the junction box for new functionality!" interface stuff with some vintage, 1980s style soldering and bypass diodes. Because I don't care about the optimizers on my well-sited array with no shading, and I don't need rapid shutdown for a ground mount array, etc.

And then proceeded to short the leads, put them in the sun, and ensure that the junction box guts didn't get hot, while observing just how brutal on panels doing this is - you really highlight the difference between cells thermally, when in "normal running," you don't see any differences in the array.

And now I'm writing all this up as a blog post. :)

I read half way through this free book by Sven Yrvind called “WITH FOUR SQUARE METERS OF SAIL AND ONE OAR” which is sort of a manifesto about building small boats and living simply. He’s a super interesting guy, I don’t even know how to sail and I was pretty glued to it. Not sure why I decided to latch on and go deep on the subject but you can find it here if you’re interested: https://www.yrvind.com/wp-content/uploa…

I've been on a sailing kick recently, and think you'd like this vlog featuring Sven and one of his boats: https://www.youtube.com/watch?v=Bca5_uyH9E4

The sheer utility of every component of the craft is awesome.
