    Post an image of your circuit as it is now. .PNG format images are preferred.

    Right now, we have no idea on how much current your panel might produce, or what you are trying to power with it.

    You have posted a portion of a circuit for an IR2110 half-H bridge driver, or a similar product.

    You have not mentioned how much current your panel can output.

    You have not mentioned what your load is.
    Are you trying to charge batteries?
    Are you powering some other load, maybe a DC to AC power inverter?
    What is the current requirement of your load?

    It will be very difficult to make any progress until these questions are answered.
