I have a new 40 watt solar panel that is replacing an old beat up panel for my signage solar lighting project.
I was testing the panel and get the rated voltage + with no load. That is not the issue,
The problem is when I cover the panel both front and back, I am still getting between 8-11V out of the panel. Plus I can see it climbing!
what is going on here? Does the panel have that much capacitance?
It' couldn't be so sensitive that it could still produce a voltage even though covered by thick cardboard could it?
