I posted yesterday about getting the second pump shed wired up to solar panels. One interesting tidbit I noticed when checking it around dusk was the fact that the panels were generating electricity quite late in the day.

Here is a picture of how low the sun was relative to the panels:

Here is the photo of the current from panels to batteries:

The most current I’ve seen was about 15.5A on a sunny day around noon time when the batteries were low. At 0.8A at dusk, this is about 5% of the observed peak.

I always imagined that the panels would stop producing electricity as the sun gets low at the end of the day but it is interesting to not that the rate of electricity generation tapers gracefully as the sunlight drops.
