   be careful check the timbers solar panels are much more of a load .

   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 http://www.unirac.com/

   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.

   This depends on the type of panels. Photovoltaic panels convert light into electricity, and are lighter than the waterfilled tube panels that are more effiicient in the UK climate. Those are heavy and you need to know the roof structure is strong enough. In either case, I suspect you may need planning approval, and you will certainly need building regs approval to connect them to the house power circuit if you use photovoltaics as they coome under the new Part P regs. Calll your town hall planning office and building control. If you dont someone will notice sooner or later and get you for it, as it is so obviously visible.
