Can a solar consultant help mitigate shading challenges?

Assessing Shading Patterns

A solar consultant will typically use specialized software and tools to analyze the site’s shading patterns. This involves creating a 3D model of the surrounding area and accounting for factors such as nearby structures, trees, and other obstructions. For example, a common rule of thumb is to maintain a minimum of 5-10 feet of clearance between the solar panel array and any nearby trees or structures to minimize shading. By identifying potential shading issues early on, a solar consultant can recommend alternative locations or orientations for the solar panel array that maximize energy production.

Mitigating Shading Challenges

One common technique for mitigating shading challenges is to use a solar panel array with a north-south orientation. This allows the panels to receive an optimal amount of direct sunlight throughout the day, while minimizing the impact of morning and afternoon shading. In some cases, a solar consultant may recommend using a tracking system that adjusts the solar panel array to follow the sun’s movement throughout the day. This can increase energy production by up to 25% in areas with significant shading. Another technique is to use a ‘solar panel array with a slight east-west tilt’ which helps to reduce shading and increase overall energy production.

Implementing Shading Solutions

Once a solar consultant has identified the shading challenges and recommended solutions, they can work with the system designer to implement the necessary changes. This may involve adjusting the solar panel array’s orientation and location, or installing additional components such as tracking systems or shading devices. A solar consultant can also provide guidance on how to maintain the system and monitor its performance over time, ensuring that the solar panel array continues to operate at maximum efficiency and minimize the impact of shading challenges.
