This can vary depending on your north-south location, but it generally ranges from 30-45 degrees for homeowners in the continental United States. Factors such as roof pitch and time of year can affect the overall efficiency of your arrays. The calculator. . Enter your address to find the optimal solar panel tilt angle for your location. In this guide, we'll break down. . Simple is the basic idea of controlling solar panel efficiency: panels generate the maximum power when sunlight strikes their surface perpendicularly, therefore forming a direct 90-degree angle. The photovoltaic cells absorb the most solar energy available at that instant when the sun's rays strike. . Tilt angle is defined as the number of degrees your array orients from the ground so it can face the sun. Panels positioned perpendicular to the sun's rays absorb maximum energy, but the sun's position changes with seasons and your geographic location. Poor tilt angle calculation can reduce. .
