I have a solar array on my roof. If I find my house in OSM, there’s a lightning bolt icon indicating there’s a solar array present. Not only that, but the exact layout of the panels in my roof is shown. I never submitted this info to anyone, Google Maps Satellite view doesn’t show them. I’m really curious where OSM got such detailed data.
I guess you could point to that as a good thing because when selling your house people could see that it has solar panels and when the solar panels were added to open street map and to your house. Like, oh, I see this house has had solar panels for at least 10 years.
