Everything you need to know about concrete ballasts for rooftop solar installations. Types, sizing, and installation considerations explained.
Concrete ballasts are increasingly popular for securing solar panels on flat roofs without the need for roof penetration. This guide covers everything you need to know about ballast-mounted solar systems.
What Are Concrete Ballasts?
Concrete ballasts are heavy blocks used to secure solar panel mounting systems to rooftops. They use weight rather than mechanical fasteners to keep solar arrays in place, eliminating the need to drill into the roof membrane.
Advantages of Ballasted Systems
Key advantages include: no roof penetration (preserves roof warranty and prevents leaks), flexibility (panels can be repositioned or removed easily), cost-effectiveness (faster installation reduces labour costs), and suitability for all flat roofs (works on concrete, metal, and membrane roofs).
Quality Considerations
Not all concrete ballasts are created equal. Look for ballasts with high-strength concrete mix, proper curing for durability, and accurate weight specifications.
