Suncalc.org is a fantastic site for tracking the sun’s movement during the year. Critical if you’re planning solar panels and your roof isn’t straightforward, for example if it has shade in a given direction. You can see the lowest sun path in winter in the top arc, and the highest is the bottom arc. The yellow band between them shows all the paths the sun takes over a given address during the year. You enter your property location and it tells you the exact path of the sun on any day, and location at any point in time. There’s a huge street tree to our north-west, that blocks late afternoon sun in winter. With suncalc I can track to the exact day when that shading starts and ends, every year.
