Anyway the video is ridicolous, LOL concerned about the heating.

If i'm not wrong in madrid they use a similar sistem almost everywhere in the new public buildings, and they have tiles with photovoltaic technologies integrated in it... ...And while in the rest of the world use it, here in Italy politicians keep talking about these things but don't do anything... proud to be italian.. :-( Another problem is that, despite the fact this technology is old and simple, prices are high, because there is a monopoly on the components.

The main issue is the high temperature which stress the cell reducing its lifetime. They put an heat exchanger but how much this devices will last? Current panels are guaranteed for 15-20 years (but they should work for 30-40 years at least), anyway I hope to see this things on market very very soon.
