How Solar Panel Angles and Alignment Are Determined

May 8, 2023

Efficiency and output are two key factors for solar panels—the angle and alignment of your solar panels will have a massive impact on how effective they’ll be for energy production. Read on to find out how solar panel angles and alignment are determined.

Seasonal Changes

Solar panel angles should be adjusted to accommodate seasonal changes in the sun’s position. In the summer months, when the sun is higher in the sky, solar panels should be tilted at a lower angle. Conversely, during the winter months, when the sun is lower, panels should be tilted at a steeper angle to capture more sunlight.

Roof Angle and Orientation

The angle and orientation of the roof where solar panels will be installed also impact the ideal panel alignment. If the roof’s angle is already close to the recommended angle for the location, panels can be mounted flush to the roof. However, if the roof’s angle deviates significantly from the optimal angle, mounting systems can be used to adjust the panel angle accordingly.

Geographic Location

The geographic location of the solar panel installation plays a significant role in determining optimal panel angles. El Paso, situated in the westernmost part of Texas, enjoys abundant sunlight, making it an ideal location for solar energy production. To maximize efficiency, solar panels in El Paso should be tilted toward the equator at an angle approximately equal to the site’s latitude. This ensures the panels capture the most sunlight possible throughout the year, leading to optimal energy production.

Shade Considerations

Shade can significantly reduce the efficiency of solar panels. To minimize shading, solar panels should be aligned to avoid obstructions such as trees, buildings, or other structures. This may require adjusting the panel angle or placement to ensure maximum sun exposure throughout the day.

Now that you understand how solar panel angle and alignment are determined, you can rest easy knowing that professional solar panel installers like NM Solar Group have the know-how to set your solar panel system up for optimal energy production.
