FAQs of Ballasted PV Mounting System

What Is a Flat Ballasted Solar Racking Systems?

Flat ballasted solar racking systems are a secure, non-penetrating mounting solution. Instead of attaching to the roof structure, they use weighted concrete blocks (ballast) to hold the solar array firmly in place. Key features include:

1.Built for Tough Conditions: Engineered to withstand heavy snow, ice, and high winds while fully complying with building codes.

2.Expertly Engineered: Our engineers calculate the precise ballast layout and structure to safely distribute weight across your specific roof, protecting its integrity based on its shape, size, and slope.

3.The Proven Choice: As the leading solution for over 10 years, ballast systems have revolutionized flat-roof solar installations.

4.Universal Roof Compatibility: Works on virtually any flat roof surface – concrete, bitumen, membrane (foil), green roofs, gravel, or trapezoidal metal.

5.Design Flexibility: Accommodates both standard and bifacial (double-sided) panels, with tilt angles adjustable from 0° to 45°.

6.Fast & Simple Installation: Pre-assembled components and minimal connections (only three screws per module row) mean significantly faster setup with less effort.

What Are the Dvantages of the Ballasted Racking System for Solar?

1. Simplified Installation: Eliminates roof penetrations, removing the need for sealing work and roofing contractors. Many systems are plug-and-play, slashing installation time.

2.Enhanced Aesthetics: Strategically placed ballast creates a clean, uniform appearance on flat roofs, especially when visible. This complements the building's architecture and presents solar as a modern, attractive solution.

3.Speed & Efficiency: Features like pre-assembled rails, minimal connections, and few screws enable quick, easy assembly on any roof covering, optimizing costs.

How Is Ballasted Ground Mount Solar Racking Installed?

1.Unpack & Layout: Unpack the pre-assembled racking components and position them on the roof according to the layout plan.

2.Assemble the Base: Configure the rails and bracing to form the base structure. Position the ballast brackets where required.

3.Install Panels: Secure the solar panels onto the assembled racking structure.

4.Add Ballast: Place the concrete ballast blocks into the designated ballast brackets to weigh down the system.
