I’m curious where the battle between paint and films goes in this new technology area, film is still ahead on total rejected power, which is why ARPA-E funded this: https://arpa-e.energy.gov/technologies/projects/passive-radiative-cooling-film https://arpa-e.energy.gov/technologies/projects/passive-radi... Film surfaces can be engineered more to withstand dirt accumulation which drops performance, but it may require more skill to apply adhesives on site compared to paint. In factory, films can be a lot easier to apply due to VOC regulation etc. Whatever the case, we need this tech deployed.
