Until recently, it’s been hard to say how many solar systems have been installed in the U.S.–if you buy panels to put on your roof, each state tracks that information differently. There’s no official central database. But a new machine learning program developed by Stanford University researchers uses AI to count solar panels in satellite images. In a new study, the team found that the n...
