> The more efficient panels are much more expensive than the regular panels (and there are no signs of this changing any time soon). I'm pretty confident we'll be replacing silicon panels with another, more efficient tech before long. Something will bust through silicon's efficiency barrier. It may or may not be perovskite-based panels, who knows, buit I still think it's exciting to see the research & gains in this area. It's great to have more options coming online.
