Snow starts to naturally avalanche at 32+ deg.
There are a couple of aspects that I design with if you want snow to slide: Angle & the big thing is giving the snow somewhere to go. If it builds up and accumulates it does not matter what angle you set it to. To install 2 modules in a column on a roof and allow for snow (depending on elevation & yearly snow levels) I will allow for 24-36 inches below just to allow the snow to drop off & accumulate slide away or melt. Roof composition influences this also, as painted metal roofs tend to slide, rusty metal kind of stick and comp roofs just hold the snow till it melts. When it melts go boating! ---------------------------------------------------------------------------- Dana Orzel Great Solar Works, Inc - NABCEP # 051112-136 E - [email protected] - Web - solarwork.com O - 970.626.5253 C - 208.721.7003 - No FAX Line "Responsible Technologies for Responsible People since 1988" P Please consider the environment before printing this email.

Anyone else find this is true? Thanks db Dan Brown Foxfire Energy Corp. Renewable Energy Systems (802)-483-2564 www.Foxfire-Energy.com NABCEP #092907-44
