<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>
<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>
