Homemade Solar Concentrator

There’s a complicated math formula for calculating the angle of a solar funnel for solar ovens, and the like. But fear not, the solar funnel math calculator is here.

Enter the width and height of the funnel, and we’ll tell you the angle.

It’s better to round up a degree or two to allow for tolerances. The problem with being too accurate is you’ll have to be pointed exactly to the sun to avoid the sun being reflected back out the funnel, which might hurt your eyes or alarm planes ;)

See the math formula post for how to apply the answer.
