From the article: >He said that the glass developed by Tesla for the solar roof tiles weigh “a third, a quarter and sometimes even a fifth” of other current concrete and ceramic roof solutions. Musk calculated that because of the weight and fragility of the current products, logistic costs and breakage are important parts of the total cost. You clearly don't get how much can be saved by handling a much lighter panel. Tiles are so much more fragile than eggs where costly solutions like paper mash carriers are used and only a fraction arrive at the customer. Also tiles are so perishable that storing them costs a ton - especially as they need expensive support infrastructures like pallets, ground and often fresh air. The thing that still confuses me is why panels less difficult to handle if one is heavier and larger than a single tile. Probably I need to move a step right to re-enter the distortion field. Right, now I feel I get it. Can't explain it but it definitely feels spacey.
