calculating shade size for summer sun—anyone tried DIY math?

buddyp41 · 2025-03-28T15:02:30Z

Been thinking about adding some shade to my south-facing windows before summer hits again. Looked into it a bit and seems like there's two main ways people figure out awning or overhang size: one is using online calculators/apps that just spit out numbers, and the other is doing the math yourself based on your latitude and sun angles. I'm kinda tempted to try the DIY math route (you know, nerd points and all), but wondering if it's worth the hassle compared to just plugging numbers into a calculator. Anyone tried either method and have thoughts on which worked better?

Haha, I feel your pain... I once built a shade sail setup after meticulously calculating angles and sun paths—only to find out my neighbor's tree blocked half the sun anyway. DIY math is always an adventure, right?
