Key item here: “These cells as they are could last one or two years without packaging,” Bulović says. “With packaging, we could extend that to five to 10 years. And that’s plenty.”
As with existing thin film cells, degradation in real-world outdoor conditions is significant and limits usefulness.

- solardev 4y agoThere are purpose-built tools for that sort of thing, whether pen and paper under a fisheye lens (https://www.solarpathfinder.com/ https://www.solarpathfinder.com/), an app, or a dedicated device like https://www.solmetric.com/buy210.html https://www.solmetric.com/buy210.html Edit: You can also do it with aerial photogrammetry and smart software, like https://sunroof.withgoogle.com/ https://sunroof.withgoogle.com/ and https://www.opensolar.com/accuracy https://www.opensolar.com/accuracy Either method would you get accurate enough readings in a few minutes (if you're onsite) or seconds (if you just use the software method). The earth's orbit and tilt is relatively predictable so really you just have to do the math (or let the software do it) to figure out how local obstructions (trees, other buildings, hills on the horizon, etc.) influence your shading.
