    <p>My cohort here that used to make PV modules thinks that something
      may have hit the back of the <br>
    </p>
    <p>module ?  Maybe somebody weed-eating around the array and
      something hit it ?</p>
    <p>We notice the cracks in Ray's cells are white. Are the backs of
      these modules white too ?</p>
    <p>Interesting if they still work but if just a couple of cells out
      of 60 or 70 are bad then it might</p>
    <p>not be noticeable, electrically ?</p>

            <br>
            I've had a colleague ask that I post a couple pictures of
            what appears to be cracks in cells under the glass.  The
            glass is not damaged.  These are Sun Edison modules, so
            apparently no warranty.  Has anyone seen this, and are these
            possibly dangerous (hot spots) or is this nothing to worry
            about?  An Infrared camera did not show any issues.<br>
            <br>
            As always your invaluable input is always appreciated.<br>
            <br>
            Thanks,<span class="HOEnZb"><font color="#888888"><br>
