Silfab hit with default in $1.3M Sunbelt case as lawsuits grow from local courts to US Supreme Court.

Silfab hit with default in $1.3M Sunbelt case as lawsuits grow from local courts to US Supreme Court. September 18, 2026 Silfab Solar's legal problems in York County just escalated after a court entered default against Silfab Solar Cells SC Inc. in a $1.3 million lawsuit filed by Sunbelt Rentals. Sunbelt filed its motion for default on September 17. The company said Silfab was served August 3 but failed to answer within the required time. This morning, the court entered default against Silfab. "Default is hereby entered against Defendant Silfab Solar Cells SC Inc." The case is the latest development in an unusually crowded legal docket surrounding Silfab's Fort Mill factory. Those disputes now stretch from York County Common Pleas Court to the South Carolina Court of Appeals and U.S. Supreme Court. Sunbelt says more than $1.3 million remains unpaid. Sunbelt alleges Silfab accumulated substantial unpaid equipment rental bills during construction of the Fort Mill facility. The companies negotiated a repayment agreement in April requiring $50,000 every week. Sunbelt says Silfab instead made only $114,295.67 in payments through June 15. Its attorneys later demanded the remaining balance and threatened foreclosure proceedings. After additional credits, Sunbelt alleges $1,313,732.45 remains unpaid. Sunbelt also recorded a mechanic's lien and seeks foreclosure-related relief against property owner Exeter 7149 Logistics. Exeter purchased the Stateline 77 property from Rockefeller Group for approximately $106 million in 2023, with Silfab as the major tenant. The deed included in court filings records the $106 million transaction. Silfab cases now span multiple courts. Court records show numerous active, stayed, and pending cases involving Silfab, its landlord Exeter, and York County officials related to the factory; * Sunbelt Rentals v. Silfab and Exeter - 2026CP4602612: Pending. Sunbelt seeks $1.313 million, plus interest and fees. Default was entered against Silfab September 18. * Century Contractors v. Silfab and Exeter - 2026CP4602680: Pending foreclosure action. Century seeks at least $532,779.37 and asks the court to allow enforcement against Exeter's property interest and Silfab's leasehold. * Superior Electrical Services v. Silfab - 2026CP4602320: Pending/ADR. Superior alleges $581,933.78 remains unpaid for electrical work and materials. * Lear's Welding & Fabrication v. Silfab entities - 2026CP4602480: Pending/ADR. Lear's alleges $321,622.99 remains unpaid. * SPG Construction v. National Partitions - 2025CP4602598: Construction dispute tied to Silfab's factory. A judge recently confirmed an arbitration award involving the massive clean-room project. Court records describe a $12 million materials contract and more than $5 million in installation work. * Silfab zoning case: A York County judge affirmed the BZA ruling against Silfab's zoning position in August. Silfab and Exeter have continued challenging the ruling. * Bivens v. York County - S.C. Court of Appeals, 2026-000199: Pending. Bivens is appealing the dismissal of his case challenging York County's permitting and zoning-compliance process. Court correspondence shows the appeal is being considered for the December term. * Buchanan v. S.C. Department of Environmental Services and Silfab - S.C. Court of Appeals, 2025-000288: The appeal challenges the handling of Silfab's state air permit. The appellate docket currently lists the case as "Ready for Consideration." * Citizens Alliance for Government Integrity v. York County - U.S. Supreme Court, No. 25-1299: CAGI filed a petition for certiorari challenging York County's actions related to Silfab's permits on federal due-process grounds. The Supreme Court docket shows the petition was distributed for the September 28 conference, with a supplemental brief filed September 11. The four major active contractor payment cases alone involve approximately $2.75 million in alleged unpaid balances, excluding interest and legal costs. More than a routine construction dispute. Contract disputes and mechanic's liens happen regularly on major construction projects. What stands out here is the concentration of unrelated creditors reaching advanced litigation stages around the same facility. Several vendors allege six-figure unpaid balances. Two creditors are pursuing property-related lien remedies. Sunbelt alleges Silfab negotiated a repayment plan and then failed to meet it. Now, Sunbelt's case has progressed to an actual default entry. The expanding docket represents mounting legal and financial pressure around a factory already facing growing zoning, environmental, and regulatory challenges. For Exeter, the disputes also carry a separate concern: contractors are increasingly looking beyond Silfab and toward interests in the $106 million Fort Mill property to secure money they allege remains unpaid.

Silfab Solar picks new director to oversee health and safety at its Fort Mill site.

Silfab Solar picks new director to oversee health and safety at its Fort Mill site. By John Marks September 9, 2026 11:28 AM Gift Article Silfab Solar picked war veteran, engineer and chemical manufacturing expert Jamie Watts as its new corporate director of health and safety. That role will oversee what's become one of the hottest topics in York County for the past three years - the safety of Silfab's site in Fort Mill. Watts will lead safety efforts at the 7149 Logistics Lane site in Fort Mill as well as in Washington state. Watts brings more than 30 years of experience in safety, operations and risk management. "His proven track record in safety leadership and operational excellence aligns perfectly with our commitment to our employees and the communities where we operate," Silfab Solar Chief People Officer Mike Boggs said in announcing the hire. Pushback against Silfab Solar's Fort Mill location. Silfab Solar manufactures and assembles solar panels. There's been public pushback against the company's Fort Mill location since officials in York County approved a tax incentive agreement to bring the company here in 2023. Silfab projected a $150 million investment and 800 new jobs. Debate began not on what Silfab would do, but where. The Logistics Lane site is zoned for light industrial uses, and it's beside a property where two schools opened in the last year. A sizeable group of concerned parents and neighbors have been consistent in their pleas to county and school officials not to allow manufacturing and industrial chemicals at the site. A zoning appeals board in York County determined solar panel manufacturing shouldn't be allowed in light industrial areas, but how that decision applies to the already approved Silfab project has been tied up in litigation. Calls for change intensify. Calls for change intensified in March when reports came in about two chemical releases at the Fort Mill site. Neither presented any danger to the public, the company and public health officials stated. Yet the Fort Mill School District closed nearby Flint Hill Elementary School for two days due to the incidents. Watts brings expertise in health and safety strategy, regulatory compliance, emergency response and large-scale industrial operations. He holds a chemical engineering degree from North Carolina State University and is a licensed engineer. Watts also let more than 250 combat missions and earned the Bronze Star and Combat Action Badge while serving during Operation Iraqi Freedom. "I am excited to work with leaders throughout the company to continue strengthening our safety culture and drive excellence across our operations," Watts said.

Made in america, powered by the sun: Infinity Drain goes solar with Silfab.

Made in america, powered by the sun: Infinity Drain goes solar with Silfab. September 3, 2026\AMITYVILLE, NY, USA Infinity Drain, in collaboration with Kamtech Solar Solutions, completed a high-performance commercial solar installation at its newly renovated headquarters and manufacturing facility in Amityville, NY. Powered by 1,200 American-made Silfab Solar 530XM bifacial solar panels, four SolarEdge inverters, and a Unirac ballasted racking system, the installation reflects Infinity Drain's commitment to domestic manufacturing. It also extends that philosophy to the way the company powers its facility. The result is a 636 kW DC system designed to generate approximately 590,000 kWh annually, supporting Infinity Drain's sustainability goals while strengthening the long-term resilience of its Long Island operations. Solar Installation Project Overview * Installation Type: Commercial * Installation Year: 2025 * Installer: Kamtech Solar Solutions, Inwood, NY * System Size: 636 kW DC / 480 kW AC (utility interconnection) * Panels: 1,200 Silfab Commercial 530XM bifacial panels * Other Components: 4 SolarEdge inverters (480V) and monitoring platform, Unirac ballasted racking * Estimated Annual Production: Approximately 590,000 kWh/year ABOUT the AMITYVILLE SOLAR project. Infinity Drain wanted their new solar system integrated into the renovation of the headquarters and manufacturing facility, not treated as an engineering afterthought. That consideration meant sizing it to the building's actual load, designing it to operate for decades, and coordinating additional competing schedules. However, a system of this size doesn't progress on one universal timeline. Utility sign-off, engineering review, and local permitting each advance at their own pace, occasionally raising concerns of the project stalling. And while the installation wasn't up and running when they hoped, Infinity Drain and their collaborating partners worked together to address each requirement and keep things moving. The payoff: a reliable system built for steady long-term performance. Why SILFAB SOLAR. The push toward solar grew out of a question Infinity Drain was already asking internally: If domestic manufacturing was central enough to the business to build a brand around, why wouldn't that same standard apply to how the company powers its own facility? That line of thinking led the team to Silfab Solar. Silfab's panels are built in the U.S., which matched Infinity Drain's own sourcing standards, and the bifacial design and efficiency gave the team confidence in the hardware itself. During the evaluation stage, as further proof the panels would hold up over the long run, Kamtech Solar pointed to Silfab's standing as a BloombergNEF Tier-1 manufacturer and its excellent product and performance warranties. Choosing Silfab was about more than selecting a solar panel. It was about partnering with a North American manufacturer whose values around quality, innovation, and long-term performance aligned with its own. - Infinity drain team Early performance & environmental impact. While the system hasn't yet logged a full year online, the early numbers are encouraging. Over its first 8 months, it generated roughly 404.5 MWh, enough to cover an estimated 72% of the facility's electricity use during that period, measured against historical consumption for the same months. Projected across a full year, Infinity Drain expects the system to offset around 70% of total electricity needs and cut an estimated 350,000 pounds of CO[2] annually. Output climbs further in warmer months; from April through August, the system is expected to cover the facility's electricity use in full. Investing in people & community. Infinity Drain treats the system as one part of a broader effort to run the business responsibly - for the people who work there, the customers it serves, and the community around it. Because the installation went in alongside a full renovation of the headquarters and manufacturing facility, it functions less like an add-on and more like a permanent piece of how the site now operates. Lower grid dependence and reduced emissions are part of the payoff, but so is a more predictable energy budget for a facility built to support domestic manufacturing for years to come. Those efficiencies extend beyond the factory floor, enabling Infinity Drain to invest further in community programs such as Mission Belly Full. Since its launch in 2020, the 501(c)(3) organization has delivered more than 115,000 meals and continues to provide weekly support to the Amityville, NY community. A model for domestic manufacturing & clean energy. In addition to domestic sourcing and a product line made with roughly 95% recycled content, Infinity Drain can now add solar power to its growing list of sustainability initiatives. They point to this installation as a marker of where its operations are headed, guided by the same principles it applies across the business: transparency, traceability, transformation, and trust.

Silfab Solar warns York County: Forcing us to move could have 'chilling effect'

Silfab Solar warns York County: Forcing us to move could have 'chilling effect' By John Marks Updated July 30, 2026 10:17 AM Gift Article Silfab Solar has issued a not-too-subtle warning to York County: Any attempt to force the controversial company to move would trigger lawsuits and have a "chilling effect" on the county's ability to recruit new business. The Canadian solar panel manufacturer made that statement in a late Wednesday letter from Silfab President and CEO Paolo Maccario to York County Council. In March, a pair of chemical releases at Silfab led to temporary school closures at nearby Flint Hill Elementary School, and heightened community concerns. His letter comes ahead of a special called meeting Thursday in York where council will meet in executive session to discuss Silfab and a recent court order limiting where solar panel manufacturing can happen. There's been pressure on the county from local lawmakers to limit Silfab's operations or move it from Fort Mill. Silfab has been a hotly debated topic since York County approved a deal three years ago to bring the company to 7149 Logistics Lane in Fort Mill. Residents argued manufacturing using chemicals shouldn't be allowed near homes and schools. The county approved Silfab plans based on its $150 million investment and 800 projected jobs. After the Silfab deal was approved, the York County Board of Zoning Appeals determined solar panel manufacturing shouldn't be allowed on properties zoned for light industrial use, like the Silfab site. The company and York County argued that rule apples to future projects, but not Silfab, since that deal was already in motion. Silfab Solar wants York County to 'follow through' on commitment. Silfab has since become an economic engine in York County, according to the letter from the company. More than 700 of the company's 1,200 jobs are in Fort Mill. The recent court ruling involved a zoning decision and wasn't related to safety or regulatory compliance, the letter said. Silfab hasn't caused off-site injuries and the company hasn't been citied for workplace injuries, the letter said. "As we follow through on our commitments, we respectfully ask our partners to follow through on the commitments they made to us, as well," Maccario said in his letter. "This includes fostering an environment in which our employees can safely and confidently come to work each day knowing that decisions affecting their workplace will be guided by facts, law and a commitment to the well-being of York County residents." Silfab it is doing everything it can to operate safely in Fort Mill, Maccairo said, and there's no basis for making the company move. The letter references challenges as Silfab has begun work in Fort Mill. "While there have been challenges as we have ramped up operations, there is no legal or public safety basis for any action that would limit our ability to operate," Maccario said. Doing so would cause harm to the company, customers, employees and their families, according to Maccario. "It would also have negative implications for the York County community and state," he said, "force unnecessary litigation regarding a taking of our property rights, jeopardize the significant investment the state and York County have made to recruit Silfab to come to South Carolina, have a chilling effect as other companies weigh business opportunities here and establish a concerning precedent that could allow zoning boards in other communities to reverse course and terminate business operations after businesses have been built and began operations." Council's 5:30 p.m. meeting Thursday doesn't have a decision on the agenda to vote on, but lists "matters for consideration" after executive session that could include a decision on the company. Growing push for action on Silfab. Fort Mill residents have been vocal at town, county and school board meetings the past three years asking that Silfab not be allowed to operate on Logistics Lane. Many elected officials throughout the area joined that call following the March incidents, and echoed it after the recent court decision. State Sen. Michael Johnson sent a letter to York County and the state environmental department on Friday asking for a cease-and-desist order to Silfab for all manufacturing operations based on the new court ruling. He posted Monday on his Facebook page that York County "needs to revoke permits immediately." The Fort Mill School District sent a letter to Gov. Henry McMaster and other state officials on Friday calling for "immediate and decisive" action to make Silfab comply with the recent court ruling. State Rep. David Martin also sent the county and the state environmental department a letter on Monday that there's now a clear court ruling showing solar panel manufacturing shouldn't be allowed in light industrial areas. Fort Mill families deserve answers, transparency and enforcement of the law, he said in a Facebook post. "The court has spoken," Martin said. "Now it is time to act." This is a developing story.

Fort Mill School District seeks restrictions on Silfab Solar facility after zoning court ruling.

Fort Mill School District seeks restrictions on Silfab Solar facility after zoning court ruling. Fort Mill School District calls for restrictions on Silfab Solar facility following court ruling. A zoning dispute involving a major solar panel manufacturing facility in Fort Mill, South Carolina is escalating - and now it has drawn in one of the community's most influential institutions: the Fort Mill School District. After a court ruling challenged the current zoning status of the Silfab Solar facility, school district officials have formally asked local leaders to restrict the company's operations, setting the stage for a significant decision that could shape land use policy across York County for years to come. For residents of Fort Mill, Indian Land, Tega Cay, and the broader South Charlotte region, this story is about far more than one manufacturing plant. It's about how rapidly growing communities balance economic development with the needs of the families, students, and neighborhoods that define them. What happened: the zoning ruling explained. The dispute centers on the Silfab Solar facility in Fort Mill, which manufactures solar panels as part of the growing clean energy supply chain in the Southeast. A recent court ruling called into question whether the facility's current operations align with its approved zoning classification - a legal determination that has significant consequences for how the plant can continue to function. Zoning classifications exist to ensure that land is used in ways that are compatible with surrounding areas. When a facility's operations exceed or fall outside the scope of its approved zoning, local governments are typically empowered - and sometimes required - to intervene. The court ruling in this case appears to have done exactly that: it identified a mismatch between what Silfab Solar is doing and what the zoning technically permits. Following that ruling, the Fort Mill School District wasted little time. School officials formally submitted a request to local leaders asking that Silfab Solar's operations be restricted in accordance with the court's findings. It's a notable move - school districts don't typically insert themselves into industrial zoning disputes - and it underscores just how seriously district leaders are taking the situation. Why the School District is getting involved. The Fort Mill School District serves tens of thousands of students across one of the fastest-growing communities in the Carolinas. York County's population growth has consistently ranked among the highest in South Carolina, and Fort Mill sits at the center of that expansion. New residential neighborhoods, commercial corridors, and infrastructure projects are constantly reshaping the landscape. When school district officials raise concerns about an industrial facility's zoning status, it signals something important: that the community's growth is beginning to create real tension between different land uses. Schools, families, and residential neighborhoods need predictability and compatibility in the areas around them. An industrial manufacturing operation that may not be properly zoned for its level of activity represents exactly the kind of friction that can emerge when development outpaces planning. While the school district has not publicly detailed every specific concern driving its request, the decision to formally petition local officials reflects a broader community interest in ensuring that zoning laws are enforced - and that the rapid growth reshaping Fort Mill doesn't come at the expense of residents' quality of life. Silfab Solar's role in Fort Mill's economic landscape. Silfab Solar is not a small operation. The company represents a meaningful piece of Fort Mill's industrial and economic identity, operating as part of the expanding clean energy manufacturing sector in the United States. Solar panel production has become an increasingly important industry as federal clean energy incentives have driven domestic manufacturing investment - and Fort Mill has been part of that story. From a purely economic development perspective, a facility like Silfab Solar brings jobs, tax revenue, and supply chain activity to the region. York County and the broader South Charlotte corridor have long positioned themselves as business-friendly environments, and industrial employers play a role in that ecosystem. But economic development and community compatibility are not always the same thing. Zoning laws are the mechanism communities use to ensure that economic activity happens in the right places and in ways that don't impose undue burdens on neighbors. When those rules are tested - as they are here - local officials face the difficult task of weighing competing interests. What this means for Fort Mill and York County residents. For everyday residents of Fort Mill, Indian Land, and the surrounding South Charlotte area, this dispute is a window into the complex machinery of local governance that shapes daily life in ways that aren't always visible. Here's what's at stake: * Zoning enforcement precedent: How local officials respond to the court ruling and the school district's request will signal how seriously York County takes zoning compliance as industrial development continues. * Community planning standards: The outcome could influence how future industrial facilities are permitted and monitored in fast-growing areas like Fort Mill and Indian Land. * School district influence: The school district's willingness to formally intervene in a land use dispute is a significant development, potentially establishing a model for how educational institutions engage with growth-related policy decisions. * Property values and neighborhood character: Residents near industrial facilities have a direct interest in whether those operations are properly zoned and regulated. The bigger picture: growth, infrastructure, and land use in South Charlotte. Fort Mill's zoning dispute with Silfab Solar doesn't exist in a vacuum. Across the South Charlotte corridor - from Ballantyne and Pineville on the North Carolina side to Fort Mill, Indian Land, Waxhaw, and Tega Cay in South Carolina - communities are grappling with the consequences of extraordinary growth. York County has added tens of thousands of new residents over the past decade, and the pace shows little sign of slowing. That growth brings tremendous opportunity: new schools, new businesses, expanded infrastructure, and a growing tax base. But it also brings challenges. Roads get congested. Schools fill up. And land use decisions that might have seemed straightforward a decade ago become flashpoints as residential and industrial interests increasingly overlap. The Silfab Solar situation is, in many ways, a microcosm of those broader tensions. A manufacturing facility that may have made perfect sense when first approved is now operating in a community context that has changed dramatically. The court ruling and the school district's subsequent action are the legal and civic systems doing exactly what they're supposed to do: prompting a community conversation about what belongs where. What happens next. Local officials in York County and Fort Mill will now need to respond to the school district's request and determine how to proceed in light of the court ruling. The possible outcomes range from operational restrictions on Silfab Solar's facility to a broader rezoning process that could redefine what activities are permitted on the site. Residents who want to stay informed about this issue - or who want to weigh in before any final decisions are made - should monitor York County planning and zoning commission meeting schedules, as well as Fort Mill Town Council agendas. Public comment periods are typically part of zoning proceedings, and community input can meaningfully influence outcomes. Stay connected with South Charlotte Report. Stories like the Silfab Solar zoning dispute are exactly why local news coverage matters. The decisions being made in Fort Mill, Indian Land, Waxhaw, Tega Cay, Ballantyne, and Pineville right now will shape what these communities look and feel like for the next decade.
