Will it slide!? Solar install for alpine town

Will it slide!? Solar install for alpine town

Hi solar folks, I recently bought a home in a small mountain town in south west BC Canada. I have quite a large south facing roof sloped at 5/12 (~24 degrees). From what I understand that is ideal for solar panels on the 49th parallel! I'm starting to look into solar panels to power our house. One day I plan to convert my gas furnace to some electric heat pumps and gas guzzling SUV to an electric car.

My roof is metal, and designed to shed snow. My city requires a snow load of ~160PSF... Last year we got ~6 ft of snow on the ground to put things into perspective. Our neighbours with shingled roofs had ~3 feet of snow on their roof.

If I were to completely cover my south facing roof with solar panels, would the snow still slide? Would I end up with major ice dams underneath the solar panels (water melting hitting the colder metal roof)? Does anyone have real life experience with this? Can it be done safely?

Solar Supports

Solar Supports I'm looking at installing a solar system at our off grid cabin this spring and I'm trying to come up with a good way to get the panels up high enough to catch decent sunlight. The roof of the cabin is not an option as there are some trees blocking it but I do have a shed that I figure I'd be able to brace the supports to, I can't use the shed roof either as it's facing the wrong direction. A couple neighbors have systems which they've put on poles that go up sort of like a street lamp or flagpole style support which is an option but I thought maybe either a frame like a scaffold kind of thing secured to the back of the shed might be a more sturdy option. What have you guys used to elevate your panels on a standalone frame, or have you seen any companies that sell good kits? I'm in BC in Canada as well. Thanks for reading. submitted by /u/dykehoncho [visit reddit] [comments] https://ift.tt/2C1elG6
