[RE-wrenches] Extreme snow load ground mount?

Sun Apr 26 13:32:59 PDT 2015

Nice rack!

However if the panels are not rated for more the 100-113 PSF, the design is still not acceptable if the AHJ wants 420 PSF right?

Q – What is the stoutest PV module out there?

Lars,

        Yes, the only way you can even consider an install like this is a pole mount, with a steep tilt in the winter to shed most of the snow.  It would help to know if the place will be used in the winter or summer  and how big of an array in KW or Sq Ft.  Customer would have to understand that you cannot guarantee it...there are some combinations of wind-snow-temp-moisture that make snow cling to anything.  If this is permitted, start dropping off cookies to an engineer.

Wrenches, 

I have a fun one for you. We have a couple of potential clients who live in the high Sierra with a 420 LB design snow load. After hunting around, not even a three rail system comes close with any module I can find, so now I'm looking for a pole top that will dump the snow, and still handle 120 mph winds. Any ideas? I would just say sorry, no solar for you,but like many of you I love a challenge.
