Ground or pole mount

mmagmmag Solar Expert Posts: 57 ✭✭✭✭
i am trying to mount ten trina 295w panels they measure 77x39.2, ten end up being around 12'x16' the spot is a western slope. so to put a ground mount in i would need poles or taller footings on the down hill side, i am wondering is the cost of the pole mount going to end up being similar to a ground mount? are there benefits of either?

    Pole mount can be adjusted for tilt angle, it makes a big difference up north, less so down south. The steep tilt also helps a lot with snow covering the panels and keeps the panels above the snow pack. Trade off is a pole mount will be more expensive to build and require more concrete than a fixed ground mount. Pole mounts have to be stiffer as the tend to get thrown around by the wind while ground mounts dont.

    My array is about twice as big as yours. I spent around $2K to build a fixed mount on wooden posts. There's some ground tilt (2 feet accross the array). Wasn't difficult to handle.

    It would cost me about $7K to put them on two metal poles.
