Quick Answer
In shaded areas, adjustable mounts are generally a better option because they allow for greater flexibility in panel orientation, maximizing solar exposure and energy production. They can also help mitigate the impact of partial shading. This is especially true for areas with tall trees or structures that cast shadows at different times of day.
Choosing the Right Mount for Shaded Areas
When it comes to dealing with shaded areas, the type of mount used can significantly impact a solar panel system’s performance. Fixed mounts, which are the most common type, are suitable for open areas with consistent sunlight but may not be the best option for shaded areas. Adjustable mounts, on the other hand, can be tilted and angled to maximize solar exposure. This is often achieved using a dual-axis tracker, which can be programmed to follow the sun’s movement throughout the day.
Techniques for Maximizing Energy Production in Shaded Areas
One technique for optimizing energy production in shaded areas is to use a combination of fixed and adjustable mounts. For example, a ground-mounted system with a fixed array facing south and an adjustable tracker array facing east-west can help capture morning and afternoon sun. Another strategy is to use a “bifacial” panel, which can absorb light from both the front and back sides, increasing energy production by up to 25% in shaded areas. This requires a clear surface behind the panel, such as a reflective sheeting or a white surface, to maximize rear-side light absorption.
Mounting Options for Shaded Areas
Some mounting options, such as a “pole mount,” are particularly well-suited for shaded areas. This type of mount allows for easy adjustment and can be used to track the sun’s movement throughout the day. Another option is a “rack mount,” which can be used on rooftops and can be adjusted to optimize solar exposure in shaded areas. When choosing a mount for a shaded area, it’s essential to consider the specific shading conditions and select a system that can adapt to these conditions.
