Are solar trackers worth it for small-scale installations?

Benefits for Large Arrays

Solar trackers can increase energy production by 20-50% compared to fixed-tilt systems, depending on the location and array size. This is because trackers can adjust the angle of the panels throughout the day to maximize energy production. For instance, a 10-kilowatt array with a tracker system in a sunny location like Arizona can produce up to 50% more energy than a fixed-tilt system.

Space Requirements and Costs

However, solar trackers require more space and are typically more expensive than fixed-tilt systems. A 10-kilowatt tracker system can occupy about 2,000 square feet of space, which may not be feasible for small-scale installations with limited land. The cost of the tracker system can also be higher, ranging from $1 to $3 per watt, depending on the type and quality of the system.

Practical Considerations

For small-scale installations, a fixed-tilt system with a pole mount is often a more practical and cost-effective option. Pole mounts can provide a decent tilt angle, typically between 15 and 30 degrees, to optimize energy production. However, if you have a large array size and enough space for a tracker system, the increased energy production can make up for the higher upfront costs. It’s essential to conduct a thorough site analysis and consult with a solar expert to determine the best solution for your specific installation.
