<DIV>Adam,</DIV>
<DIV> </DIV>
<DIV> Many roofs in our area here in the
Sierra are metal and shed snow in less desirable locations around the
house....part of living at this elevation. Different people deal with it
in a variety of ways one of which is a snow shovel, another is snow brakes or
heat tape (ouch) and everything in between. The snow brakes I've used
are this style (not necessarily recommending this product) <A

<DIV> </DIV>
<DIV> I'm not sure mounting the PVs in
landscape is a better option in this instance. As I understand your
installation, if the customer absolutely does not want to deal with snow sliding
off the array, I would probably install snow brakes a foot below the lower edge
of the array...assuming that 20" of comp at the bottom is not enough to prevent
it from sliding....because its not. I know some people have had issues
with frames being torn off the bottom of PVs from sliding snow, but I think they
get more snow than you do.</DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> </DIV>
<DIV> Its too late (?) now but if a 1-2"
gap was left between the rows, a custom-made brake could have been made to be
mounted below the lower edge of top row and protrude up just a couple
inches above the plane of the array to take some of the load of the snow off of
the lower snow brakes/PVs. My thoughts are predicated on the assumption
that the 60" you mentioned is total for the year, not at one time.</DIV>
<DIV> </DIV>
<DIV> The best scenario would be to
convince the customer that relieving the array of the snow (let it slide) is the
best option for power output and reducing the number of holes in his roof for
attaching the snow brakes. "If you buy this PV system, it comes with a
free snow shovel"</DIV>
<DIV> </DIV>
<DIV>What a deal.</DIV>

<DIV dir=ltr>As an aside, I often notice arrays that fill a roof (gutter to
ridge) that are often located in places I would assume it would not be good
for snow to shed (i.e. a walkway or driveway). I'm wondering if this is
something that is communicated with customers? Do those of you in snowy areas
sacrifice size of an array to compensate for this or just come to an
understanding with a customer that this is a hazard they (or their cars) could
face.</DIV>

<DIV>It's a comp roof @ 30 degrees. The array could be as close as 20" to
the bottom edge of the roof. Two rows of panels in portrait on two different
roof sections. It's a 7.2kW system. We are in NY and snow seems to be
completely variable these last few years but looks like the average has been
about 60" traditionally.</DIV></DIV>

<DIV>The snowguards were an afterthought, and I'm not sure if I can switch
the panels to run in landscape...which would be preferable if snow is going
to shed slower.</DIV>

<DIV dir=ltr>Hey Wrenchers,
<DIV><BR>
<DIV>I'm looking into snow guards for an array that would shed snow
right into a driveway. So far I'm only familiar with Alpine. If anyone
has other recommendations let me know? </DIV>
<DIV><BR></DIV>
<DIV>I haven't had to use any sort of snow guard so far, but I guess I
should be prepared for winter production to really take a hit?</DIV>
