[RE-wrenches] Dealing with snow

[August Goers]

Hi Wrenches,



I'm working on a PV installation best practices training agenda and I'm trying to gather some info on dealing with snow. I don't have experience with snow because I've always worked in the California coastal area.



Here are some questions which I'm hoping some of you might be able to answer:



Roof mount applications:



1. Do you typically mount arrays flush to the roof? If so, I'm assuming that roof pitches are generally designed to handle the various snow load and snow-shed scenarios depending on how much snow the area sees?

2. Does the height off the roof matter? In other words, is it better to mount low to the roof or higher above the roof. Does snow wedge under the array?

3. Are there products out there designed to help shed snow?

4. Any other tips or opinions? Any stories?



Are there any tips for dealing with pole and ground mounts other than tilting the panels really steep?



Thanks in advance. I'm hoping to hear from experienced Wrenches and to put together a general set of guidelines for dealing with snow and ice in cold climates.



Best,



August
