    So what do you think?

    KC 120-1 Pannel Temp. 32.7C
    Full solar noon sun on panels
    6 pannels measued 15.40 to 15.92 volts
    6 pannels measured 7.52 to 7.96 volts
    array open circuit voltage 19.43

    This system is wired siries parrallel for a battery voltage of 24 volts. Any opiniions.

    Thanks Chuck

    Sounds like some of the panels are bad--if you look closely, you may see some dark/burned areas through the glass.

    From what I have heard, they will replace the entire set (and may also give you some money for labor too). No reason not to contact them and get the process started.

    Thanks BB I just faxed the RA into them and am awaiting the results. I looked at the front of the pannels but with my old eyes didnt see anything. I figgure that volt meter dont lie if you got a good one:D

    Thanks Chuck

    I will add that we have once or twice here chased problems that did not make sense when a DVM seemed OK at some voltage/currents and looked "sort of OK if there was a problem" at others...

    Given that these panels are most likely bad (bad production lot)--you don't have much risk here...

    But if you ever get into debugging and certain readings don't make sense--getting/borrowing a second meter (or calibrating/checking your current meter) is worth the money/time.

    This was my experience. Replacement was finished just 2 days ago. I live out in the sticks, and just happen to have a Solar Install company a few miles away. My replacement set (60) was refurbished KC-120s, I heard som others were getting KC-135s a while back.
