Yep! This is why solar panels typically have another diode wired in series with them, so they don't draw/waste power and emit light at night!

In the solar world they call it a blocking diode.

No, there is no series diode. There is an antiparallel diode to prevent solar cells from turning current into heat when they are shadowed.

A quick search of the term in my post instead of just saying no would have been useful. https://www.sciencedirect.com/topics/engineering/blocking-di...
