Ballast Systems

Our ballast solar mounting systems are designed for fast, secure, and non-penetrative solar panel installations—especially on flat roofs where drilling into the surface is restricted or undesirable. Utilizing concrete blocks, stone pavers, or other weighted materials, these systems ensure structural stability without compromising roof integrity.

Ballasted systems are increasingly popular in urban and commercial installations, particularly in buildings with membrane roofs, low-load capacity surfaces, or leased properties where permanent alteration is not permitted. Our modular design allows for flexibility, fast deployment, and cost efficiency across a wide range of projects.

Key Features:

• Non-Penetrating Design: Installs without drilling into the roof, avoiding leaks and preserving insulation. Ideal for EPDM, TPO, or bitumen roofs.

• Stable and Secure: Weighted with concrete or pre-cast ballast blocks to resist wind uplift and meet structural code requirements.

• Adjustable Tilt Angles: Common tilt options include 10°, 15°, and 30° to maximize energy generation depending on latitude.

• Modular System: Compatible with all standard solar panel sizes, easily scalable from small residential setups to large flat-roof commercial arrays.

• Durable Materials: Built from anodized aluminum and stainless or galvanized steel for corrosion resistance and longevity.

• Wind Deflectors Available: Optional aerodynamic deflectors reduce ballast weight requirements by minimizing uplift forces.

Our ballast systems support both south-facing and east-west installation layouts. The east-west configuration offers high space efficiency and energy yield per square meter, making it especially suitable for commercial rooftops with limited space.

Applications:

• Commercial building flat rooftops

• Residential concrete or membrane roofs

• Temporary installations and mobile solar setups

• Green roofs and lightweight structures

• Sites where roof penetration is prohibited by regulation

We provide detailed structural calculations for wind and snow loads based on local conditions, ensuring full compliance with standards like AS/NZS 1170, IEC 61215, and UL 2703. Our engineering team can also offer custom ballast layout designs to optimize system performance while minimizing overall weight.

All ballast systems are pre-assembled or supplied with easy-to-follow installation guides, reducing labor costs and speeding up deployment. For clients seeking customized kits or OEM/ODM services, we offer flexible options tailored to brand requirements, packaging, and project scale.

By using our ballast mounting systems, EPC contractors and solar installers can deliver reliable, roof-friendly, and efficient PV installations that meet today’s technical demands without the need for structural alteration or complex permitting.
