Angle between photovoltaic panels and sunlight
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.

Solar zenith angle is the angle between the sun and the zenith (directly overhead point) in the sky. Understanding this angle is crucial for determining sunlight intensity.
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.
