What are costs associated with managing shading for solar arrays?

Question

Accepted Answer

Shading Mitigation Strategies Shading can significantly reduce solar array performance by blocking sunlight from reaching the panels. Tree trimming or pruning can be an effective solution, but it requires regular maintenance to ensure optimal coverage. A typical cost for tree trimming services is between $200 to $500 per visit, depending on the size and number of trees. Annual visits may be necessary, especially for trees with a high growth rate.
Shading Mitigation Systems For larger or more complex shading issues, installing shading mitigation systems may be the most effective solution. Tracking systems, such as solar panel trackers, can increase energy production by up to 25% by adjusting the panels’ angle to maximize sunlight exposure. The cost of a tracking system can range from $1 to $3 per watt, depending on the system’s complexity and size. Solar panel cleaners can also be an effective solution, with a cost of around $0.05 to $0.10 per watt per cleaning.
Cost-Benefit Analysis When evaluating the costs of shading mitigation strategies, a cost-benefit analysis is essential to determine the most effective solution for your solar array. Consider factors such as the cost of tree trimming or pruning, the cost of shading mitigation systems, and the potential energy savings. For example, if a tree trimming service costs $300 per year and saves 10% of energy production, it may be a worthwhile investment. However, if a tracking system costs $2 per watt and saves 25% of energy production, it may be a more cost-effective solution.
