Project Snapshot: 165kW of High-Performance Rooftop Solar
Sun Ballast’s 165kW rooftop solar project in Colchester, Vermont, that cut installation time in half with smart design and American-made innovation.This public works rooftop installation, features Sun Ballast’s ballasted solar racking system known for its simplicity and structural integrity. It’s UL2703-certified precast concrete ballast blocks manufactured by EZ-CRETE in the USA, the system delivers optimal performance in New England’s demanding weather conditions.
Key Highlights:
Zero Roof Penetration: The ballasted-only racking requires no drilling or mechanical fastening—eliminating roof damage and simplifying installation.
Engineered for Harsh Climates: Designed to withstand heavy snow and wind loads, this system thrives in the Northeast.
Modular & Scalable: Ideal for public, commercial, and industrial flat-roof systems of all sizes.
Up to 70% Less Labor. 100% Smarter Solar Installation.
Time is money in solar construction. The Colchester team reported a 50% reduction in labor time versus traditional roof-mounted systems. That efficiency comes from thoughtful engineering and the power of precast concrete.
Why It Works:
Precision Precast Concrete, Made in the USA
- Engineered to Last:
Precision-cast at 5,000 PSI strength. Unlike standard concrete that may crack or degrade over time, Sun Ballast blocks are designed to withstand the elements and outlast the solar system they support—without crumbling, weakening, or breaking down.
- Simple Interlocking System:
The Connect System’s grid design self-braces, eliminating the need for additional cross-bracing or structural supports.
No Complex Racking Systems: Say goodbye to intricate steel or aluminum structures. Sun Ballast’s rail-less, pre-assembled design eliminates the need for cutting, measuring, or assembling traditional racking—letting installers focus on what matters most: clean, efficient panel placement.
Connect System: Lightweight, ultra-reliable, and built to withstand extreme weather—the Connect System revolutionizes ballasted racking by integrating all supports into a reinforced, wind-resistant network. This interconnected design minimizes roof load while maximizing stability and durability.
Sun Ballast’s precast concrete ballast blocks are proudly manufactured in the United States and engineered to meet the rigorous demands of modern solar racking.
