Quick Answer
Solar arrays can be successfully used in shaded areas, although performance may be reduced due to decreased solar irradiance.
Choosing the Right Mounting System
To maximize energy production in shaded areas, consider using a pole mount for your solar array. This allows for optimal tilt and azimuth adjustments to track the sun’s movement and make the most of available sunlight. A sturdy pole mount can also help to reduce shading from surrounding structures, such as trees or buildings.
Shading Analysis and Mitigation Techniques
When assessing a shaded area for solar array installation, conduct a thorough shading analysis to determine the extent and duration of shading throughout the day. This can be done using software tools or site measurements. Techniques to mitigate shading include pruning trees, installing a trellis or screen to block direct sunlight, or reorienting the solar array to minimize shading impacts.
Case Study: 5kW Pole-Mounted Solar Array in Shaded Area
A 5kW solar array was installed on a pole mount in a shaded area, resulting in a 15% reduction in expected energy production. However, by adjusting the tilt and azimuth of the array to optimize energy production, the system was able to generate an average of 80% of its predicted output. This demonstrates the importance of careful site analysis and system design in shaded areas, where even a well-designed system can still experience reduced performance.
