    hi all

    A solar panel is required to charge a battery . the voltage, current and the capacity of the battery in Ah are known. now how do we proceed to select the solar panel to match these requirements ?

    in general how are solar panels specified ?

    It's a very simple problem.Just ask the shopkeeper which solar panel is best?

    Solar panels are cool in the way that you can connect them in different configurations of parallel and series to get the desired current and voltage output that you need exactly like a battery would be connected. In parallel VT = V1 + V2 with current equal and in series IT = I1 + I2 with voltage equal.
    So you just buy the basic one and slap a few of them together to get your power output. You will need some sort of conversion stage of coarse but that can be found easy enough if you look up battery charging in a power book.

    A lead acid battery is usually charged at (A Hr/10) amps for ten hours. One can charge at higher currents but efficiency goes down. Just make sure that your panel has double this ampere rating since panels are specified at peak insolation. Also the useful power of a solar panel will be between 9 AM and 3 PM.
