Is it Viable to Combine Fixed and Tracker Mounts in One System?

System Design Considerations

When designing a hybrid system that combines fixed and tracker mounts, it’s essential to consider the layout and orientation of the solar panels. A common approach is to use a fixed mount for the lower-angle panels and a tracker mount for the higher-angle panels. For example, a 5-7 kW system might use a fixed mount for the lower 2 kW of panels and a tracker mount for the remaining 3-5 kW. This configuration can help optimize energy production while minimizing the cost of the tracker system.

Tracking Efficiency and Costs

Tracker mounts are typically more efficient than fixed mounts, especially for higher-angle panels, but they also come with a higher upfront cost. A well-designed hybrid system can help balance the benefits of tracking with the costs, but it requires careful planning and simulation to ensure optimal performance. For instance, a study by a leading solar engineering firm found that a hybrid system with a 30% tracker-mounted area can achieve a 10-15% increase in annual energy production compared to a fixed mount system, while also reducing the tracker cost by 20-30%.

Practical Implementation Examples

Several solar companies have already implemented hybrid systems in the field, with promising results. For example, a recent installation in California used a fixed mount for the lower 10 panels and a tracker mount for the remaining 20 panels, resulting in a 12% increase in annual energy production and a 25% reduction in tracker costs. When designing a hybrid system, it’s crucial to work with experienced engineers and suppliers to ensure that the layout and equipment selection are optimized for maximum efficiency and minimal costs.
