How to connect a diode on parallel solar panel connection?
I am making a foldable solar charger. I will have 3 panels connected in parallel, for a total rating of 5 volts at 1.5 amps. This will connect directly to a USB boosting converter for a maximum output of 5V at 1 amp for charging or powering a USB device. No batteries will be connected. Can I just use a diode on the + wire where it connects to the USB charger or do I really need one on each panel? Thanks for any help!
