Yep, snow load is a concern, but they’re mounted at a high angle due to our latitude. That does however increase wind load, and we’re located in somewhat of a gulley that funnels wind. I saw a friend’s professionally installed ground mount buckle under a failed piece of strut so figured I’d splurge for stronger stuff where possible, especially since I’m DIYing it and looking forward to the tax credit, reducing costs to match.

Do rooftop installations avoid that problem, then?
