SolarDave: Installing solar panels on a tile roof can be tricky, what is your approach ? John Shaw: The easiest way to do PV on a tile roof weather that is curved Spanish tile or flat concrete tiles is to use building integrated PV product. Sharp has a product, Open Energy has a product, both of them basically hang on the battens. They are silicon cells so they are not the thin film amorphous that simply means that they are as efficient as a standard panel from Sharp or Evergreen or what not. They get screwed in to the roof decking just like the concrete tiles. They intergrate with the concrete tile with a lip, this perticular one made by Open Energy is a 35 watt tile, it replaces 3 concrete tiles and it is basically the same height as a concrete tile and the width of them is the same and it is really the easiest way to do solar on a curved spanish tile or flat concrete tile roof. If one wants to do standard tiles, there is a couple of ways to do it – the most laborious way would be to remove all the tile and and fasten to the beam. But the way Sharp suggests that we do it is basically retrofiting so we back out just the tiles necessary where we need to make our attachments. Anderson Hoke: You can pull one or two or 4 tiles right where you need to make the connection. You can pull out …
