    Hello Friends,

    i am working on the solar panel and i want to increase the output current for the charging of my phone battery please suggest how i can do it
    Solar panel-6V ,100mA

    If you need close to the 6V - say 5V - and you can only get 100mA out of the panel, then that's it. You need a new panel that can supply the correct amount of current. :eek:/

    That is probably the max for the panel, too....I'd find one that has more overhead since you'll rarely get the max...

    Get more light? Seriously, you can only get so much power out of it, so if it produces 100mA at 6V, then to make 500mA the voltage needs to be 1.2V for the power to be constant.
    You will either need to get a better larger panel, or charge your phone really slowly.

    You can still use the panel you have but you may need more panels... This is called wiring your strings in parallel... Look at my blog entry for an understanding about how solar arrays work and why you can only get so much current out of them.

    Get 4 or 5 more solar panels.
    Get 1 or 2 bigger panels.

    You might use a reflector to direct more sunlight towards your solar panel, which should increase its' output. Be aware that you don't want the solar panel to get overly warm.

    You might use some aluminum foil over scrap wood, or perhaps some kind of concave shape(s) to focus the light.
