Quick Answer
The choice between fixed and tracking solar panel mounts depends on the amount of sunlight your location receives, the type of solar panels you have, and the amount of space available for the solar array. Fixed mounts are simpler and less expensive, while tracking mounts can increase energy output by up to 30%. Consider factors such as roof orientation and shading when making your decision.
Fixed Mounts: A Simple and Affordable Option
Fixed mounts are a popular choice for solar panel installations, especially on smaller systems. They are typically less expensive and easier to install than tracking mounts. However, fixed mounts can result in a 10-15% loss in energy output due to the sun’s movement throughout the day. This may not be a significant issue in areas with minimal shading, but it can impact system performance in areas with frequent cloud cover or obstructions.
Tracking Mounts: Increased Energy Output
Tracking mounts, on the other hand, can increase energy output by up to 30% compared to fixed mounts. This is achieved by aligning the solar panels to follow the sun’s movement throughout the day. Tracking mounts use a motorized system to adjust the angle of the panels, which can be adjusted to follow the sun’s path at different times of the year. This requires a more complex installation and is typically more expensive than fixed mounts.
Considerations for Choosing Between Fixed and Tracking Mounts
When deciding between fixed and tracking mounts, consider factors such as roof orientation and shading. If your roof receives direct sunlight for most of the day, a fixed mount may be sufficient. However, if your roof is partially shaded or receives indirect sunlight, a tracking mount may be a better option. Additionally, consider the type of solar panels you have and the amount of space available for the solar array.
