Ask HN: Map overlay of solar radiation?

I'm interested if anyone has a Google Maps overlay or equivalent with estimates of solar output in specific locations, taking into account Z-axis stuff like nearby mountains and buildings, as well as tree canopy cover.

The closest resource I've found [1] has the kind of UX I'm looking for, but it's geared toward properties rather than any Lat/Long location. There's other resources out there [2] but most are pretty basic. Tree canopy cover specifically seems challenging to estimate and there's some research [3] on estimating that, but it doesn't look like it's been applied yet.

A friend who is considering a solar installation in a remote location asked me, and I was surprised given the growth of solar that this kind of data set isn't available or hasn't been created. It sounds like something that could be a valuable resource.

Thanks HN!
