Figuring the overhang for the sun in my area

[soomb]

Does anyone have a link or a calculation that would take into account the overhang needed to keep the sun off of a wall from late spring to early fall?  The dates are flex, but I am just looking for the general how to (y+x=z).

Thanks

Might be something that Glenn could help you with as he is the master of the universe.  No he just deals with solar and it has a lot in common.

All well and true, John but I rely on John's Sunkit for help with questions like these.

You might check out my Underground Cabin for general information -   Also use the search button on the blue line above to search key words on the site and see what else is here.  I'm on wind and solar.

Here's a sun angle calculator.

Of course you have to know your latitude, longitude and how many hours difference you are from London time (GMT).

I used this program to figure out my overhang sizes.

Thanks.  Everything I have found involves good ole math.  My favorite.  But it sure beats cooking in the hot summer sun.
