The question isn't how the solar tiles compete against adding panels to an existing roof - the panels are not going to be beaten in this comparison. The question is, how do the tiles compare to building a roof from scratch. And then possibly adding solar panels to the roof in addition. And of course, for all the cases where people don't want (or even are not allowed) to put panels onto their roof.
And, at least in Germany, most home owners wouldn't be able to put solar onto the ground for a lack of real estate.

- _ph_ 7y agoI think the solar tiles only make sense, when you are not able to install solar panels. Be it for geometry or optical reasons.
