How do you install solar panels on a slate roof?

Just like a tile or other stone roof, one or more tiles is generally removed, and a standoff is attached through the sheathing to the rafter below. The standoff is then flashed just like a vent. Racks are then mounted on these standoffs. You can see examples of mounting systems on <a href="http://www.unirac.com/" rel="nofollow">http://www.unirac.com/</a> Solar hot water can be heavy, and you would want to be sure of the strength of the underlying roof, especially if there is a tank on the roof. Solar electric is light. It's probably worth it to get a pro to do the install on this kind of roof, as it's not as forgiving as, say, asphalt shingle.  more
