    I have a solar panel . I am going to build a shunt regulator as the charger for the battery.

    The solar panel puts out about .6 amps 24VDC open circuit.

    I have read that I should use Schottky diode because of it's low forward volatage.


    On hand I have a 1n5820, 1n5818 and a 1n5817


    Looks like the 817 has the lowest forward voltage and is 1 amp.


    Just wanted to check if this was a good choice or use one of the other diodes I have on hand or just order something else.

    Thanks for the quick response.

    Yeah I ran across those before

    This is a work in progress. For my first version I want to keep things as simple as possible. I'm planning on adding improvements later.

    What do you think about what I have on hand?

    With what you have, I would use the 5817.

    When you start to expand, those extra volts add up though.
