BM4 Ballasted Roof System

BM4 Ballasted Roof System by Grace Solar is a revolutionary solar mounting solution designed for flat roofs in commercial, industrial, and residential settings. Engineered with high-strength aluminum alloy (AL6005-T5) and stainless steel, this system eliminates roof penetration, ensuring structural integrity while adapting to 5°-20° tilt angles. Certified by UL, TUV, and AS/NZS1170, it withstands wind speeds up to 60m/s and snow loads of 1.4kN/m². With modular pre-assembly and a 10-year warranty, BM4 reduces installation costs by 30% and achieves ROI within 5 years. Globally proven in 100+ countries, it’s the go-to choice for sustainable energy projects.

Features

Grace Solar’s BM4 Ballasted Roof System offers drill-free installation on flat roofs, compatible with most panels. Durable aluminum/stainless steel construction, 20+ year lifespan, and global certifications ensure reliability.

No Roof Penetration, Zero Damage

The BM4’s ballast design eliminates drilling, preserving roof waterproofing and reducing maintenance risks. Ideal for leased buildings or heritage structures.

High-Strength Aluminum Alloy

AL6005-T5 material with anodized coating ensures corrosion resistance, passing JIS H8601 salt spray tests for 30+ years in harsh climates.

Rapid Modular Installation

Pre-assembled components reduce on-site labor by 40%, with a 2-person team completing 50kW/day. Compatible with tilt angles 5°-20°.

Wind Tunnel Certified Stability

Wind deflection brackets and 2350mm ballast bars secure arrays against 60m/s gusts, validated by EN1991 standards.

Cost-Effective ROI

Lower material weight (vs. steel) cuts shipping costs by 25%, while 20-year durability minimizes lifecycle expenses.

Universal Panel Compatibility

Adjustable clamps fit 30-46mm frames (mono, bifacial, thin-film), with KYR copper grounding for NEC compliance.

Eco-Friendly Design

Anodized surfaces and recyclable materials align with EU Green Deal, reducing carbon footprint by 15% vs. traditional systems.

Smart Load Distribution

Front/rear support feet optimize weight balance, allowing 20% less ballast than competitors while meeting AS/NZS 1170.

10-Year Quality Assurance

Comprehensive warranty covers components and performance, backed by Grace Solar’s 48GW global installation track record.
