Frequently Asked Questions

Have questions about our Manually-Adjusted Single-Axis Tracker? Some of these might help you.

What is a manually-adjusted single-axis tracker?

A manually adjusted single axis tracker allows solar panels to rotate along one axis to optimize sun exposure throughout the year, with tilt adjustments performed manually at scheduled intervals rather than automatically.

How do ballast boxes work in this system?

Ballast boxes provide structural stability by using on-site materials, eliminating the need for ground penetration and making the system ideal for landfills, rocky terrain, or sites with soil restrictions.

How often does the tracker need manual adjustment?

Manual adjustments are typically performed seasonally (2–4 times per year) to optimize tilt angles based on the sun’s position, improving energy yield compared to fixed-tilt systems.

What are the benefits compared to motorized trackers?

Manually adjusted systems offer lower upfront costs, reduced maintenance, no motors or actuators, and greater long-term reliability while still increasing energy production over fixed structures.

Is the system suitable for harsh weather conditions?

Yes. The structure is engineered for wind and snow loads, and the ballast design enhances stability while avoiding foundation work, making it suitable for challenging environments.
