My 4th solar panel came in, again shipping surprisingly quickly from Thailand in under 2 weeks. Soldered it up and added bypass diodes on all of them in case there's some shade.
I also found a much better place to tap into constant 12V so wiring it up will be much easier this time around.
I'm hoping this will extend my battery life a bit more. The car has sat for about 1 week and is at 13.31V, which is fine, but it would be nice if it could go 2 weeks before reaching 13.3V.
