I need help on building some DIY solar projects (portable)
I have done a lot of research and visited many sites but still cannot figure out a few things with a portable solar charging project that I’m working on… I need help with figuring out a solar design to charge say my phone. Is it possible to hookup a wall charger to the output part and it wiil do all the work? Also I’m including batteries and Need to know how to set it up so that the phone will be powered by the panels and battery and the charge will be there only when I plug in the phone… No wasted energy.
So here’s all of my knowledge from research:
I know that solar is different from plugs because when solar cells absorb sunlight they immediately turn sunlight into Direct Current (DC) electricity and an inverter can then change it into Alternating Current (AC) which is what appliances that plug into your house use, but phones and things like that run off of DC.
-The workings of volts amps and watts.
-Wall chargers invert AC to DC and control energy output.
-My phone charges on no more than 12 volts and 1 amp
-A Voltage regulator could be needed so the battery does not get overloaded with energy
-I need a diode to put on the part that goes to the USB port so the energy doesn’t go back
-The diode could be void if wiring in the wall charger would work. I still don’t know if it will work like that
-Also it was said that a switch could keep the battery charging and not sharing electricity with an idle port
