    Is longevity currently a deal breaker?

    Asking because I’m pretty sure just saw an article about solar panels from the 90s that were still working at 70+% capacity

      It’s an issue for perovskite cells. “Traditional” silicon cells (which makes up probably 90+% of current installs) last 40+ years.

      Longevity issues combined with harmful rare mineral extraction kinda eats ass in the long run
