Hi, I’m trying to plan how to build a solar panel to charge a car battery, but with solar cell’s only providing 0.5volts I will need 34 cells to do it! I can use some dc-dc booster to make 3.5volt became 17? thanks
hey stop . don’t use a car battery for solar panel. use deep cycle battery or sealer…
