Quick Answer
Position small solar arrays in forested areas near the top of a south-facing slope, ideally at an elevation of 15-20 feet off the ground, to maximize sunlight exposure and minimize shading.
Choosing the Right Location
When selecting a location for a small solar array in a forested area, it’s essential to consider the local topography. Look for a south-facing slope with a slight incline, as this will allow the solar panels to receive direct sunlight for most of the day. Avoid areas with dense tree cover or overhead obstructions that can cast shade on the panels. Aim for an elevation of 15-20 feet off the ground to minimize interference from surrounding vegetation.
Maximizing Sunlight Exposure
To ensure optimal sunlight exposure, consider the angle of the solar array in relation to the sun’s path. A general rule of thumb is to tilt the panels at an angle equal to the site’s latitude plus 10-15 degrees. For example, in a location with a 40-degree latitude, tilt the panels at 50-55 degrees. This will allow the solar panels to track the sun’s movement throughout the day and maximize energy production.
Minimizing Shading
Shading from trees or other obstructions can significantly reduce the efficiency of a solar array. To minimize shading, consider using a “tree-clearing” technique where you remove branches and foliage from trees within a 10-15 foot radius of the solar array. You can also use tree trimming techniques to maintain a clear path for sunlight to reach the panels. Additionally, consider using a solar array with a higher wattage per panel to compensate for any shading that may occur.
