No, neither can I. But help is at hand. Sandtoft are marketing their Calderdale range of concrete roof tiles as PV ready. These tiles have been around for a while, so the fact that they are compatible with Solar Century’s C21 solar tiles is down to luck, not design. But good on them for finding this new marketing angle.
In fact, the Solar Century website indicates that all the roofing majors have products which are compatible with their solar tiles, but I had never come across it being used as a selling point for tiles until today, when interviewing Joan Barker about her selfbuild in Yorkshire. Whether this proves to be a significant sales bullet remains to be seen, but it certainly influenced Joan’s buying decision.
