Hey there, thanks for helping in advance, I’m new to the forums only recently got into trying diy solar power stuff.
The question I have is if I should use diodes for my 5v 1.25w solar panels? I’ll be connecting 3 of them in parallel, then wiring them up to the sunflower solar power manager: https://core-electronics.com.au/sunflower-solar-power-manager-5v.html
I’ve searched around and the common thing to do seems to be one diode for each panel, but the power drop would be painful seeing the panels already produce such little power.
My goal is to make a solar power bank/charger for low power devices that can charge with 5v 1a.
Thanks for reading! Here’s the solar panels I’m using (got them from eBay, they had some generic name with no info on protection circuits built in) :
