I've never worked with solar cells, although I have read a lot from them. I understand the need for diodes on them to prevent a battery discharge, but I'm having a little problem.
As far as I know, any diode has a voltage drop. Let's say 0.6V on average in my experience.
If I connect those 5V panels in parallel with the charger, would I run in under voltage problems? In the description is stated that input voltage should be 5V.
But then series panels would be more or less 9V and we are clearly on the over voltage side.
Are diodes necessary in this application? Would the charger prevent the battery discharge? I'm kind of confused arranging this power setup and would appreciate any help.
