Are these the space-grade multi-junction panels? Are the Loon panels size-constrained or cost-constrained ?
The article itself is odd - most PV will go to utility and commercial scale. Even on rooftop, aesthetics are possibly down the list after durability, reliability, efficiency and cost.
- walrus01 8y agoFrom the photos I've seen, no, they are not using triple junction GaAs cells. Boeing/spectrolab cells are incredibly expensive. They used high efficiency 156mm monocrystalline silicon cells. Just not in a glass + aluminum frame like you'd see on a roof. edit: at least in 2013 they were using thin film amorphous silicon, or what appears to be CdTe thin film flexible, not rigid cells encapsulated in clear lightweight membrane. https://www.wired.com/images_blogs/business/2013/06/20130609-3B6B2491-660x439.jpg https://www.wired.com/images_blogs/business/2013/06/20130609...
