The solar energy revolution has fundamentally altered the emergency response landscape. While the environmental and economic benefits of photovoltaic systems are undeniable, these installations have introduced a critical safety challenge that traditional firefighting methods simply cannot address.
Solar panels continue generating potentially lethal levels of DC electricity as long as they’re exposed to light – even when damaged, disconnected, or during active fire incidents.
“The challenge is clear,” explains Jim Foran, CEO of PVSTOP International. “Standard emergency measures like circuit breakers and isolation switches only disconnect downstream equipment.
“The panels themselves keep producing power, forcing first responders into defensive strategies that often mean allowing fires to burn rather than engaging with an energized PV system.”
This fundamental limitation has created what Foran describes as “the DC Danger Zone” – a dangerous void between existing safety protocols and the unique challenges posed by solar PV installations. It’s a safety gap that PVSTOP has spent the last decade systematically closing through innovative technology and proven operational deployment.
PVSTOP’s breakthrough lies in its ability to stop power generation at its source.
“There are only two ways to de-energize solar panels at the source of power production,” Foran explains. “You can either turn off the sun, or you block the light from reaching the panels – because light is the source of power.”

The company’s specialized polymer coating blocks light from reaching PV cells, effectively switching off panels regardless of system configuration or damage condition.
Independent testing verifies that PVSTOP reduces DC current to safe levels within seconds of application.
“Traditional isolation methods only interrupt the circuit downstream from the panels, leaving the PV modules themselves live when exposed to light,” Foran continues. “Our technology addresses the fundamental issue – we eliminate the power generation entirely, creating a truly safe work environment for emergency responders and electrical technicians.”
The system’s operational simplicity belies its sophisticated engineering. Emergency responders follow a straightforward three-step process: pull the safety pin, aim at the panels, and squeeze the lever. The coating can be applied safely from up to 10 meters away, providing critical standoff distance during emergency operations.
“The beauty of PVSTOP is that it is a simple solution to a complicated problem,” Foran notes. “It does exactly what it says on the can.”

Beyond immediate de-energization, PVSTOP eliminates arc flash hazards and forms a weatherproof barrier protecting damaged panels for up to 12 months, ensuring continued safety during system assessment and repairs.
What sets PVSTOP apart isn’t just its technology – it’s the company’s proven operational track record across diverse emergency environments. From London Fire Brigade’s pioneering adoption to the FDNY’s deployment across HAZMAT squads, PVSTOP has demonstrated real-world effectiveness that’s reshaping global fire safety protocols.
“We are now rolled out in many countries around the world; everywhere from Australian Fire Departments to the Singapore Civil Defense,” Foran explains. “PVSTOP is used by 90% of the fire brigades in the UK.”
Procurement by the FDNY represents a particularly significant milestone. “Notably, the FDNY, the largest fire department in the US, were one of the first adopters of our product in the US. That was a hugely validating appraisal and support to receive,” Foran notes.
After comprehensive evaluation starting in 2019, the department implemented PVSTOP on all hazmat vehicles and released training videos accessible to over 250,000 firefighters across the United States, which is now channelling into hundreds of fire departments across the US.” Foran explains.
“What we’re seeing is a fundamental shift in how fire services approach solar installations,” Foran observes. “Rather than defensive strategies that limit operational capability, PVSTOP enables aggressive intervention that can save lives and property.”
While fire risks capture headlines, arc flash events represent an equally serious but often overlooked hazard in PV systems. These high-energy electrical events can occur in damaged or faulty installations, creating immediate danger zones that conventional personal protective equipment cannot adequately address.
“Arc flash protection requires understanding the fundamental limitations of traditional safety approaches,” Foran explains.

“Standard electrical PPE has voltage ratings that often max out at 1000V DC – insufficient for many commercial, industrial and utility PV systems. Arc flash PPE, while available, is extremely bulky and creates heat stress risks, especially during extended operations or on rooftops.”
PVSTOP’s source-level de-energization eliminates arc flash risks entirely by stopping power generation.
This capability provides protection that no amount of PPE can match, creating genuinely safe work environments for both emergency response and routine maintenance operations.
PVSTOP’s upcoming drone delivery system represents the next evolution in solar safety technology. Developed in partnership with XAG, the world’s largest agricultural drone company, this system addresses the specific challenges of large-scale installations and high-risk environments.
“Manual application methods are effective across most installation types,” Foran explains. “But when you’re dealing with solar farms, Building Integrated Photovoltaic Systems (BIPV) on high-rise buildings, or floating installations, manual application becomes impractical or impossible.”
“We’ve seen some horrendous cladding fires in the past, like Grenfell in the UK”, Foran notes. “If the cladding is fully electrified, you could face the electrification of the entire façade. The whole point of the PVSTOP Drone is to respond quickly if one side of the building is involved, coat it fast and make it safe for first responders to get in and do their jobs.”
The XAG platform has been extensively modified to carry 50-70kg payload capacity with 15-20 minutes flight time, enabling coverage of hundreds of square meters of solar modules in a single flight.
PVSTOP has developed a comprehensive three-stage methodology for managing commercial and industrial PV safety risks: Detect, De-energize, Extinguish (DDE).
This systematic approach addresses the critical vulnerability of rooftop commercial installations that are typically “out of sight and out of mind” until fires reach advanced stages.
“Commercial rooftop PV systems present unique challenges because they’re largely invisible to building occupants,” Foran explains. “By the time someone notices smoke or flames, the incident is already well-developed. Early detection systems are crucial for effective intervention, but they must be integrated with rapid de-energization capabilities.”
Detection: Early detection systems provide crucial early warning through continuous thermal monitoring and pattern recognition for developing fault conditions.
De-energization: PVSTOP’s unique capability eliminates power generation at source. Unlike traditional isolation methods that only interrupt downstream circuits, PVSTOP’s light-blocking technology stops the fundamental power generation process.
Extinguish: With power eliminated at source, emergency responders can deploy appropriate suppression methods without electrical hazards. PVSTOP’s fire-retardant properties provide additional suppression capability while encapsulating toxic particles.
The DDE methodology represents a fundamental shift from reactive emergency response to proactive risk management, providing building owners with a comprehensive framework for protecting commercial PV investments while ensuring occupant and responder safety.
Environmental protection represents a critical but often overlooked aspect of solar fire safety. “Solar panels are fundamentally very safe, but when they are burning there are toxic chemicals used in the manufacturing of the solar cells that can be released into the atmosphere,” Foran explains. “Testing has proven that the toxic nanoparticles can cause silicosis of the lungs.”
PVSTOP’s environmental credentials have been rigorously validated through testing by the European Commission Environmental Technology Verification (ETV) program and the Environmental Protection Authority (EPA) in Australia.
The coating is non-toxic, non-carcinogenic, contains no PFAS, PFOS or PFOA chemicals and is environmentally friendly in both wet and dry states.
“In the modern world, you can’t cut corners on safety, whether it’s life safety, safety of the environment, or the safety of the buildings and occupants in the communities in which you operate,” Foran emphasizes.

“In addition to extinguishing a Class A fire, PVSTOP will also smother and encapsulate toxic nanoparticles from burning panels to ensure they are not being released into the environment,” Foran notes.
Recognition that technology alone cannot solve complex safety challenges has driven PVSTOP‘s comprehensive approach to training and certification. The company’s e-learning platform and international network of training partners enables scalable competency development across global markets.
“Training and education have been lacking and there is limited information available in the market for PV safety,” Foran notes. “We recognized this very early on. Currently, many stakeholders in the world are still unaware of the depth and breadth of risks associated with PV systems.”
The training platform establishes PVSTOP as a global authority on solar safety, creates a database of certified operators worldwide and provides liability protection for both users and companies. Major fire services including the FDNY have integrated PVSTOP training into their standard protocols.
“Third party accreditation and recognition are critical. We are the only product of our type in the world that is independently accredited and certified,” Foran emphasizes. “This is particularly prevalent because we operate in high-risk environments – no one can afford to take a manufacturer’s claims at face value.”
PVSTOP’s validation extends across multiple international standards bodies, including ISO certification from the European Commission – Environmental Technology Verification (ETV) Program, providing the credibility essential for deployment in life-safety applications.
As renewable energy adoption accelerates, PVSTOP’s role extends beyond individual solar installations to the broader interconnected energy ecosystem. Solar PV systems serve as primary power generators for Battery Energy Storage Systems (BESS) and Electric Vehicle charging infrastructure, creating complex safety challenges that traditional approaches cannot address.
“The renewable energy ecosystem is creating unprecedented challenges for fire safety,” Foran explains. “BESS and EVs introduce complex fire risks, but solar PV systems are often the power source driving these installations. Our ability to safely de-energize the power generators provides a critical control point for the entire ecosystem.”
This ecosystem perspective positions PVSTOP as essential infrastructure for the renewable energy transition rather than simply emergency equipment.
PVSTOP’s development pipeline reflects both immediate market needs and longer-term industry transformation. The drone delivery system addresses urgent capability gaps in high-risk environments, while advanced monitoring integration and AI-driven deployment optimization represent the next phase of technological evolution.
“Looking ahead, we have barely scratched the tip of the iceberg. Many stakeholders are still unaware of PVSTOP and haven’t fully recognized or grasped the risks associated with PV systems,” Foran notes. “We aim to be standard equipment on every fire truck, with every electrical service technician and at every commercial, industrial and utility PV system site.”
The company’s global distributor network spanning over 30 countries provides the foundation for rapid market expansion, with PVSTOP positioned to capture the growing demand for specialized solar safety solutions.
Insurance companies increasingly recognize the value of documented risk mitigation, with some offering premium discounts for installations meeting modern safety standards. The economic argument extends beyond insurance to operational continuity, regulatory compliance and liability protection.
“Organizations face strict workplace health and safety obligations with serious consequences for non-compliance,” Foran notes.

“PVSTOP provides documented risk mitigation that demonstrates duty of care compliance while enabling practical protection for personnel. It’s not just about emergency response – it’s about comprehensive risk management.”
The cost of major solar-related incidents can be devastating. Property damage, business interruption, environmental remediation and liability exposure create financial risks that far exceed the cost of effective prevention measures.
PVSTOP’s journey from innovative startup to global market leader demonstrates how effective technology, rigorous validation, and strategic deployment can transform entire industries. The company’s success with major fire services worldwide has established new benchmarks for solar safety while proving that comprehensive protection is both technically feasible and operationally practical.
As the renewable energy transition accelerates, the challenges PVSTOP addresses will only become more critical. Solar installations are becoming larger, more complex and more integral to essential infrastructure. The company’s technology, operational experience and market position make it uniquely qualified to lead this evolving safety landscape.
“The question isn’t whether traditional approaches are sufficient – operational experience has clearly demonstrated they’re not,” Foran concludes. “The real question is how quickly organizations can implement comprehensive strategies that address the unique characteristics of modern solar PV installations. PVSTOP provides that solution today, with the proven track record to back it up.”
For fire safety professionals, the message is clear: solar PV safety requires specialized solutions designed specifically for these unique challenges.
PVSTOP’s global operational success provides the blueprint for effective implementation, while its continuing innovation ensures readiness for tomorrow’s even more complex renewable energy landscape.
