JJ from Veregy, Illinois

SunBallast just makes so much sense. It’s a very streamlined install which has saved our crews so much time. Once we got going with jigs we were laying blocks crazy fast and saving labor. Not needing anchors makes things easier. Concrete racking will last forever and it looks good on the roof!

DM homeowner in FL

I was going to do a traditional ground mount system with concrete footers in my backyard. Was quoted 9600$ and would have been 2 days of labor for 2 people using heavy equipment. With SunBallast I did the whole system DIY with less than 3000$ in racking, by myself in a single day. The ROI using this is so much better.

AP from AltPower, NY

On a roof this tall with a strict no anchor constraint, I knew no racking could do it. But SunBallast with their thorough engineering and super solid product made it happen and made the project possible on a very special architectural “blue roof” in Manhattan for a high profile client. Everyone else needed anchors, which would have killed the project.

Frequently Asked Questions (FAQ)

Clear and complete answers to the most common questions about Sun Ballast systems.

Does Sun Ballast damage the roof?

No. Sun Ballast racking systems are designed to rest directly on the roof surface with no roof penetrations. Rubber protection mats are used beneath the concrete blocks to preserve the roofing membrane and prevent any damage over time.

How are the solar panels secured to the system?

Solar panels are fixed using stainless steel clamps that attach directly to threaded inserts pre-cast into the concrete blocks. This ensures a solid mechanical connection without drilling or anchoring into the roof or the block.

Isn’t a concrete system too heavy for my roof?

Weight is a common concern, especially on commercial roofs. Sun Ballast systems are engineered to distribute loads evenly across the roof surface, reducing point loads. Depending on the project, total system weight typically ranges between 4 and 8 PSF, including the solar panels. Each layout is specifically designed to meet structural requirements.

Are Sun Ballast systems wind-resistant?

Yes. All systems are engineered using wind tunnel testing and fluid-dynamics analysis to ensure stability even in high-wind conditions. Ballast weight and layout are customized for each site to meet local wind load requirements.

Can Sun Ballast be used without roof anchors?

Absolutely. Sun Ballast is a fully ballasted racking system, designed to achieve high wind resistance without mechanical roof attachments. In most cases, no anchors are required.

What tilt angles are available?

In the U.S. market, Sun Ballast systems are available with flush mount, 5° and 10° tilt angles, optimized for flat commercial roofs and high-density installations.

Is the system compliant with national standards? Will it pass permitting?

Yes. Sun Ballast racking systems are UL 2703 certified for grounding, fire resistance, and mechanical load performance. Selected configurations also comply with UL 3741, providing certified PV hazard control to reduce electrical risks for installers and firefighters. Sun Ballast designs are fully code compliant and have achieved a 100% permit approval rate on first submission with every AHJ we’ve worked with.

How is grounding handled?

Grounding is integrated into the system. The clamps electrically bond the module frames together, while a single jumper bonds rows in the north-south direction. Grounding lugs connect the array to the grounding conductor in full compliance with NEC requirements.

What roof types are compatible?

Sun Ballast systems can be installed on most flat or low-slope commercial roofs, including TPO, PVC, and EPDM membranes, gravel roofs, paved surfaces, and green roofs. Maximum roof slope is typically up to 5° (up to 10° in specific conditions).

How long does delivery take?

Thanks to stocked inventory and U.S.-based production, most orders are ready for shipment within a few business days, ensuring fast project timelines.

Do you offer engineering and layout support?

Yes. Our technical team provides project-specific engineering support, including ballast configuration, wind load calculations, and layout optimization. Engineering documentation can also support the permitting process when required.

Where are Sun Ballast systems manufactured?

Sun Ballast racking systems for the U.S. market are Made in USA, with the main production plant in New Hampshire and additional satellite plants across the country to ensure competitive nationwide delivery to the job site.
