      There isn't really a "correct" answer to your question. It depends
    largely on the technology that you are trying to simulate. I would
    recommend that you refer to the Type50 documentation for the
    mathematical definition of the concentration ratio in Type50 and
    then choose an approximate value for your situation. You can of
    course test the simulation's sensitivity to the concentration ratio
    by running with a value that is somewhat below your initial estimate
    and one that is somewhat above your initial estimate. If you find
    that the results depend highly on the concentration ratio then you
    can spend additional time to choose a more accurate value.<br>
    kind regards,<br>

        <div>Dear sir,<br>

        I am using Type 50e (PV-THERMAL COLLECTORS - CONCENTRATING
        COLLECTORS - CONSTANT LOSSES - NO CELL OPERATING VOLTAGE) for
        simulating a Concentrating photovoltaic cooling system. I have a
        doubt that, How I can give (choose) a concentration ratio (Suns)
        for concentrator. Please guide me for the same.<br>
