Quick Answer
Choose single-axis mounts for optimal energy production, especially in areas with varying sun angles, while fixed mounts are more suitable for locations with consistent sun patterns.
Understanding Your Site Conditions
When deciding between single-axis and fixed mounts, start by assessing your site’s conditions. Consider the latitude and longitude of your location, as well as any surrounding obstacles that may impact solar panel performance. Single-axis mounts, which can track the sun’s movement in one axis, are ideal for sites with varying sun angles, typically those above 30° latitude. If your site is below 30° latitude, such as in the southern United States, a fixed mount may suffice.
Mount Selection Criteria
Evaluate your site’s sunlight patterns and available space to determine the best mount type. For example, if you have limited space and consistent sunlight, a fixed mount with a south-facing orientation may be the most efficient option. Conversely, if you have ample space and variable sunlight, a single-axis mount can track the sun’s movement and optimize energy production. Consider the cost and maintenance requirements of each mount type, as well as any local building codes or regulations.
Mount Configuration Techniques
When configuring a single-axis mount, ensure the tracker is aligned with the north-south axis and tilted at an angle equal to your site’s latitude. For fixed mounts, orient the solar panels south-facing to maximize energy production. Consider incorporating a tilt mechanism to adjust the panels’ angle seasonally, typically at a 30° to 40° tilt for optimal winter performance.
