    Hi,

    I'm wondering if there's a way to up the amperage on a 10v solar cell that about supplies about .6 amps. Would a step down converter work? Basically drop the voltage and increase amperage or is my thinking on this flawed?

    Thanks!

    Ve haf vays of doing this but the bottom line is wattage minus efficiency losses in the converter. Whatever amount of watts the solar panel can do is the limit. The best conversion efficiency you can do is about 90%
    So, what's your goal? 5 volts at 1.1 amp?

    The panel I'm looking ( or ones similar) are 10w/12v/.58amp.
    I'd like to get 1-1.5amp if possible but I'm just curious to see what the results would be.

    Now you have the math. Happy hunting.

    You should look for a DC/DC converter, and at 12V input, you should be able to find a whole bunch of cheap solution to your need if you know a specific output voltage.
