Yeah I guess but then you need a big roof probably. I was hoping they could be more efficient to double their performance, so half the space could be used (and possible half the cost).
There is not much room for optimization left. Best solar cells get close to 23% efficiency, apparently the current theoretical maximum is a little over 30%.
it is already something you can do, if you put enough solar panels

But we will see :)
