For maximum output, the sweet spot for solar panels in the continental U.S. is facing roughly south and tilted between 15 and 40 degrees, according to the Department of Energy. That keeps the panels in the sun longer than other setups—which means more electricity per panel per year and bigger savings on your utility bills.

Apr 20, 2022· The optimal tilt angle for a PV panel will differ throughout the year, and will also vary by latitude. If a solar array is located at a latitude of 50°, the optimal tilt angle would also be 50°. The further the location is from the equator and the closer to the poles, the higher the tilt should be for the panel to face the sun.
