<div dir="auto">I second Dana's assessment. The idea is to allow the snow to remove itself if possible. <div dir="auto">We always mount the top row as close to the peak as possible to prevent snow build up above. In the old days, when arrays were smaller, I'd recommend a good coat of RainX every year as it does help snow slide easier, but roof mounted large arrays can be difficult, at least. </div><div dir="auto"> I've found that snow held beneath the bottom row of modules can build up and prevent module snow from sliding off, often refreezing as even harder to remove ice. </div><div dir="auto"> The long and short, to me, is that snow removal is a real pita and why we've got so many ground mounted arrays in Maine....</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto">Daryl</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Oct 1, 2025, 11:09\u202fAM Dana Orzel via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hey there, Chris I\u2019ve never used Sno retention on the bottom of an array. I\u2019ve always thought that clearing the array was the basic idea. I understand if there\u2019s a doorway underneath it a raise that hold snow for long periods of time as in most of the winter tend to get iced up and I have multiple photos of array is coming off of roofs due to snow not sliding off mostly due to either being east or west facing.<br>
I suppose if I had a large area of roof above the array, I might do Sno offenses above the array, but not below the array<br>

I have used the Alpine SnowGuard in the past, but it\u2019s not the easiest to install, especially when the leading edge of the module is close to the drip edge on a multi-story building. There don\u2019t seem to be many other options on the market, so curious if there are other offerings or methods that people have found helpful. <br>
