A bit late to thread but; 1) I'm wondering why the tiles weren't larger? Wouldn't this make laying them much cheaper in a world where labor is such a significant cost for building. Aside from the shingle look I'm surprised these dont come in 1mx1m type sizes plus some smaller sizes for edges. I cant imaging this want discussed so curious if I'm missing some obvious logic here. 2) If you didn't have a ceiling would these let light through and further reduce electricity usage? 3) The cells seems to be a small proportion of the tile. Is this something they expect to increase so they will increase power generation ability significantly over future releases?
