Very nice. Confirms that installing solar panels on my roof simply isn't economical.
Guess installers would find something like this handy.

#12I thought this could solve the following problem: when camping during a mountain hike, figure out where to set up the tent, by knowing at which time you will be woken up by sunlight. Unfortunately this app doesn't seem to take elevation into account -- I don't know if there is some other tool that can do it.

#13good job! would be great if you could add polygon params and datetimes in the url so it would be easier to share

#16The drag handles are a bit finicky/small to grab, and would be nice to be able to set the heights as a group. Otherwise great!

I made a tool for this. Check out https://shademap.app/@37.72457,-119.60944,10.69315z,16470110...
Re: Show HN: Google Maps Shadow Calculator
#18Very neat! An idea that often came up amongst coworkers while walking to a lunch spot during the hot summers was being able to get walking directions that preferred routes in shadow. We had our own routes we came up with that didn't add much time to the total trip but had a massive increase in shade versus almost none on the fastest route. This reminds me a lot of that, though you would need good data on building hei…

#19so knowing the buliding height we could figure out which time and day the aerial picture was taken? And given time and day we could figure out how high the buildings are. Could this be used to generate large scale 3d building models automatically? Does anyone know whether this has been attempted?

A lot of places have lidar data available that can be used for that.

#20Nice work.
If your interested in using this for evaluating solar production then check out https://solcast.com/
There is a free version. I have it hooked this up to Homeassistant and predicting output for my home solar rig.
