Here's a look at the best solar panel angles of 30 major US cities: Scroll to the top of this page to use our Solar Panel Tilt Angle Calculator.

The optimal tilt angle for solar panels typically equals your location's latitude. For most of the continental United States, this means angles between 25-45 degrees.

To do that, follow this calculation below: Height Difference = Sin (Tilt Angle) x Module Width ***Make sure you're calculating in degrees, not radians*** In this case, I am using a SolarWorld module with a width of 39. 41 inches at a tilt angle of 15º.
