Sunshade traces sunlight across every tree, roof and hill for any address, any day of the year, to the minute. See live shadows, hours of direct sun per day or growing season, the sun on a parcel, a roof's solar potential, and which shade trees keep summer sun off your walls. It uses national LiDAR surveys where countries publish them and an OpenStreetMap-based estimate everywhere else.
Sunshade needs JavaScript and WebGL.
