As they mention in the article though, there are lots of applications that aren't space-limited but are structurally-limited (warehouses) in that they can't support the weight of solar panels without more engineering.
I did think it was strange that they obfuscated the W/m^2 statistic by only presenting W/kg and kg/m^2. I suppose focusing on watts per kilogram better aligns with a breakthrough in installations with poor structural support for heavy panels.
