If you think you might find it useful to tilt the panels (high latitude, winter) We (my tech and I) found a cheap and easy 4 way tilt mount: Piano hinge on both short sides, attached to roof at each corner with homemade L brackets. Remove 2 bolts from one end, hinge up. OR remove one bolt from each end, loosen the others and tilt up on using the bolts as hinge points. If you look closely you can see them on the centre panels. The panel in the foreground has been disconnected to move it out of the the shadow of a building behind us.
