Is It Possible to Retrofit Existing Solar Panels with Trackers?

Choosing a Retrofit Tracker System

When retrofitting existing solar panels with trackers, the primary goal is to maximize energy production. This can be achieved by using a single-axis tracker, which is a more cost-effective option compared to dual-axis trackers. A single-axis tracker can increase energy production by up to 25% compared to a fixed installation, depending on the system size and location. For example, a 5 kW system with a south-facing tilt angle and a latitude of 35 degrees can see a 20% increase in energy production with a single-axis tracker.

Mounting and Installation Considerations

Retrofitting existing solar panels with trackers requires careful planning to ensure a secure and stable installation. The mounting system should be designed to handle the increased loads and stress caused by the tracker’s movement. This may involve using reinforced mounting hardware and adjusting the panel’s tilt angle to accommodate the tracker’s axis of rotation. When selecting a retrofit tracker system, consider the panel’s age, condition, and the system’s overall design to ensure compatibility and optimal performance.

System Upgrade and Optimization

To maximize the benefits of a retrofit tracker system, it’s essential to upgrade the existing system’s components, such as the inverter and monitoring system, to take advantage of the increased energy production. This may also involve optimizing the system’s configuration and performance through software upgrades or adjustments to the tracker’s settings. Additionally, consider conducting a site analysis to identify any shading or obstructions that may impact the tracker’s performance and adjust the system accordingly.
