When a high-volume component failure hits a utility-scale solar site, the stakes involve more than just lost kilowatt-hours. For Original Equipment Manufacturers (OEMs), their brand reputation is on the line. For asset owners, their long-term ROI is at risk. Since 2012, Sunstall has operated as the “special ops” team of the solar industry stepping in to resolve massive manufacturer defects with a level of logistics and discretion that keeps the industry moving forward.

A Decade of Technical Problem Solving

Warranty work is a unique beast. It requires a contractor who can move backward through the installation process as efficiently as they move forward. Our track record in this space isn’t just about turning wrenches, it’s about managing complex recovery projects that most installers aren’t equipped to handle.

Our experience at scale includes:

• The 4,000-Module Precision Swap: When a specific batch of junction boxes was identified as a fire and performance hazard, we managed the removal and replacement of 4,000 modules already mounted on rooftops. This required surgical precision to ensure no damage to the existing racking or roof integrity.
• The 850,000-Part Louisiana Project: In one of our largest recovery efforts to date, we managed the exchange of nearly a million components for an OEM in the challenging, humid environment of Louisiana. This wasn’t just a repair; it was a massive logistical feat involving thousands of man-hours and strict supply-chain coordination.

Why Discretion is Our Greatest Asset

In the world of OEM warranty work, we understand that “no news is good news.” Our partners trust us because we operate with a white-label mindset.

Warranty work isn’t just about technical skill, it’s about logistics and discretion. We manage the ‘invisible’ repairs that keep the industry’s reputation intact while ensuring the asset performs to its original spec.

We act as the bridge between the manufacturer and the end client, resolving the issue before it becomes a headline or a legal dispute. We provide the data, the photo documentation, and the serialized tracking required for warranty closure, all while maintaining a professional distance that protects the OEM’s brand.

Beyond the Fix: Recommissioning for the Future

A repair is only as good as the commissioning that follows it. Our process doesn’t end when the last part is swapped. We treat every warranty project as an opportunity for an Inspection Health Plan. We don’t just replace the faulty part; we inspect the surrounding environment checking for thermal hotspots, torque marks, and structural integrity—to ensure that when we leave the site, the system is performing better than the day it was first energized.

Summary of Expertise

• Scale: Proven ability to manage part counts in the hundreds of thousands.
• Logistics: Expert handling of “in-and-out” logistics to minimize site downtime.
• Documentation: Detailed reporting for insurance and warranty compliance.
• Confidentiality: A strict adherence to NDAs and brand protection.
