    <p>We designed a system for a location at almost 12000 ft that gets
      huge snow loads.  We just added a third rail under the modules
      (roof mount 4:12), and its held up well for over 10 years of
      torture.  No snow guards either.  It does however, not clear in
      the winter, and is not used until May.</p>

          <div dir="ltr">We've been installing Alpine Snowguards with
            great regularity for the past few years.  We operated under
            the incorrect assumption that they were rated for
            150psf snow loads based on materials of theirs that
            indicated that at weights higher than 150 an engineer should
            be consulted.  We were also unfortunately unaware that 6"
            depths should be cleared until quite recently.  We are
            experiencing a winter of above-average accumulation and
            we've had multiple failures (minor, but failures
            nonetheless) at the lower edge of arrays with the Alpine
            product installed.  The "snow dogs" which get placed
            throughout the array are bomber but the bottom edge is
            somewhat weak and can break easily.

            <div>As a company we are currently discussing how we
              tactfully reach out to clients that have this product
              installed regarding the 6" rule and whether we should
              proactively remove the product knowing full well that in
              certain areas of our installation territory we can see
              accumulations easily 10 times that.  As for alternate
              products we have not come across anything that claims much
              higher capabilities than this.  </div>
            <div><br>
            </div>
            <div>We have not seen failures on the solar module frames
              and fortunately only on the guard itself (so far).  But
              it's still only March and there's likely a lot more snow
              to come so that remains to be seen.  </div>
