The NS-Roof Ballast-1 is a solar roof ballast system designed for flat roof photovoltaic installations. Instead of drilling into the roof membrane, the array is anchored with weighted ballast blocks, so the waterproofing layer remains intact and the building’s roof warranty is preserved. The frame is produced from AL6005-T5 aluminium profiles with an anodized surface and stainless-steel fasteners for corrosion resistance in outdoor service. The system is engineered for wind loads up to 60 m/s and snow loads up to 1.4 kN/m², and supports a tilt angle range of 5-15° for typical flat roof layouts. Optional wind deflectors reduce uplift forces, which lowers the ballast weight required and therefore the load placed on the roof structure.
Key Selling Points
Drill-Free, Roof-Friendly Anchorage
Ballast blocks provide the anchorage, so there are no roof penetrations. The membrane is not damaged, leak risk is avoided and the building’s roof warranty is preserved.
Fast, Cost-Effective Assembly
A high degree of pre-assembly and an intuitive component design shorten installation time and reduce on-site labour cost.
Anodized AL6005-T5 and Stainless Steel
High-strength aluminium alloy profiles with stainless-steel hardware deliver corrosion resistance for long-term rooftop exposure.
Engineered for Wind and Snow
Rated for wind loads up to 60 m/s and snow loads up to 1.4 kN/m², giving a stable base for flat roof arrays.
Optional Wind Deflectors
Wind deflectors cut uplift forces on the array, reducing the required ballast weight, the overall roof load and material cost.
CE Certified, 10-Year Warranty
The system carries CE certification and is covered by a 10-year warranty.

Models and Options
The NS-Roof Ballast-1 is supplied as a configurable ballasted flat roof system rather than a fixed catalogue part. Buyers select the tilt setting within the 5-15° range, choose a finish of silver, black or a customized color, and decide whether the array will be equipped with wind deflectors. Because the deflectors reduce wind uplift, projects in higher wind zones can often run with less ballast weight, which lowers the roof load and material cost. Final configurations are confirmed against project wind and snow conditions.
Materials and Structure
The structure uses aluminium alloy AL6005-T5 profiles with an anodized surface for the load-bearing members, combined with stainless-steel hardware at the connections. This pairing is chosen for corrosion resistance and stable mechanical performance in outdoor rooftop environments. The system is a ballasted arrangement: weighted blocks hold the frame in position, and no fixing is driven through the roof covering. Components are designed for a high degree of pre-assembly, and the optional wind deflectors are fitted to the array to manage uplift forces.
Applications
Residential flat roof solar installations
Commercial and industrial flat roof PV arrays
Public and infrastructure buildings with flat roofs
The system suits outdoor rooftop conditions including wind, snow and hail pressure exposure. Xiamen 9sun Solar Technology Co., Ltd. exports to markets including Japan, Korea, the Philippines, Singapore, Armenia, Bulgaria, Cuba, Lebanon, Malaysia, Mongolia, Switzerland, Saudi Arabia and Thailand.
Customization
Color is available in silver, black or a customized finish. Tilt angle can be specified within the 5-15° range, and wind deflectors can be included or omitted depending on the project wind and ballast strategy.

FAQ
Does the NS-Roof Ballast-1 require roof penetrations?
No. The system uses weighted ballast blocks for anchorage and avoids roof penetrations, which protects the roof membrane from damage and potential leaks and helps preserve the building’s warranty.
What wind and snow loads is the system rated for?
The ballast system is engineered for wind loads up to 60 m/s and snow loads up to 1.4 kN/m².
What tilt angle can be used?
The system supports a tilt angle range of 5-15°.
What materials are used?
Aluminium alloy AL6005-T5 with an anodized surface, together with stainless-steel hardware. This combination is selected for corrosion resistance and long-term outdoor reliability.
What colors are available?
Silver and black are standard, and customized colors can also be requested.
Can wind deflectors be added?
Yes. The system can be equipped with wind deflectors that reduce wind uplift forces on the array, which minimizes the required ballast weight and lowers the overall roof load and material costs.
Is the system certified and warranted?
The NS-Roof Ballast-1 holds CE certification and is covered by a 10-year warranty.
Is the system pre-assembled for faster installation?
Components are designed with a high degree of pre-assembly and a simple, intuitive layout, which reduces installation time and on-site labour cost.
