Photovoltaic panels and sun angle
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.

When the sun is lower in the sky, solar panels need a greater tilt angle to receive direct sunlight. When the sun is higher, panels require less tilt.
The angle of your solar panels affects the amount of sunlight they receive, which in turn affects their energy output.
As a general rule, the best angle for solar panels is roughly equal to your latitude, but several factors can impact this calculation. This includes roof pitch, shading, and season.
In a perfect world, solar panels always face the sun at a perpendicular angle.
