Frequently Asked Questions
Have questions about our ground-mounted racking system? Some of these might help you.
What is a dual-axis solar tracker with ballast foundation?
A dual-axis solar tracker follows the sun in both tilt and rotation to maximize energy production. With a ballast box foundation, the system is stabilized using weight instead of pile driving, creating a non-penetrating solar mounting solution.
Why choose a ballast foundation for solar projects?
A ballast foundation eliminates ground penetration, making it ideal for landfills, brownfields, rocky soil, and sites with underground utilities. It enables faster installation and minimal site disturbance.
How much more energy does a dual-axis tracker produce?
Dual-axis solar trackers can generate 25–40% more energy than fixed-tilt systems by continuously aligning panels with the sun throughout the day and year.
Is a ballast-mounted tracker stable in high winds?
Yes. The system is engineered for site-specific wind loads and includes calculated ballast weight and automatic wind stow positioning for structural stability.
Where is this system typically used?
It is commonly used for landfills, capped sites, brownfields, restricted-ground projects, and temporary solar installations requiring ground-mounted solar without piles.
