LTV Technologies Hosts Virtual Industry Webinar on Solar PV Safety and Compliance

Online Webinar Hosted from LTV Technologies and Supplies, Heilbron — April 24, 2025 — In a landmark virtual event, LTV Technologies & Supplies brought together top industry minds and safety advocates to explore urgent risks and overlooked regulations surrounding solar photovoltaic (PV) installations. The webinar, titled “Understanding PV Safety and Risks”, aimed to raise awareness and inspire action around fire safety, electrical risk mitigation, and regulatory compliance within the fast-growing solar sector.

The event was streamed live from Heilbron and recordings were made available to key industry invitees who could not attend. Participants joined from across a wide range of disciplines, including:

Emergency Services, Municipal Fire Departments, Engineers, PV System Installers, Battery Suppression Technology Providers, Professional Cleaning Services, Construction, Energy Specialists, and Technical Consultants.

Powerful Presentations from Global and Local Experts

The session featured two keynote presentations:

Alex Keene of PVStop International (UK) introduced the concept of the “DC Danger Zone”, explaining how solar panels continue producing high-voltage direct current (DC) even during damage or fire. Alex demonstrated how PVStop’s innovative removable water-based polymer light blocking coating is used globally by fire brigades to instantly make solar panels safe by blocking the light—from a safe distance of up to 10 meters.

Willem Beukes, a leading South African Structural and Fire Engineer from WIAM Consulting, outlined the current state of compliance with SANS 10400 regulations, detailing how most fixed PV installations are implemented without professional sign-off, risking fire propagation, structural overload, and dangerous live systems during emergencies.

A Clear Message: Solar Must Be Safe to Be Sustainable

“PV safety cannot be an afterthought. As South Africa moves toward energy independence, we must balance growth with responsibility,” said Johan Bosman, PV Safety Advocate and CEO of LTV Technologies. “This webinar was about educating and empowering every stakeholder—from the engineer to the cleaner to the end user.”

To honor their participation and commitment to safety, attendees received a ‘PV Safety Shield Award for attendance’, while the presenters were recognized with a ‘PV Safety Shield Award for Presentation’. Though not officially accredited, these awards reflect LTV’s commitment to recognizing shared learning and community engagement.

Next Steps: PV Safety Conference Announced

In light of the overwhelming response to the webinar, LTV Technologies is proud to announce its next initiative: a PV Safety, Risks & Maintenance Conference to be held in August 2025. The conference will include sponsor exhibitions, practical demonstrations, and panel discussions, with a strong focus on technical accuracy and safety innovation.

🗓️ Venue: To be confirmed — planned for Midrand or Johannesburg
💡 Sponsorship and Exhibition Opportunities Available
🎫 Limited Seating — Details to Follow

Key Solar Safety Risks and Considerations
  1. Electrical Hazards:
    • PV arrays produce electricity whenever exposed to sunlight or artificial lighting.
    • DC cables, often rated up to 1500 VDC, can cause lethal electrocution and arc flash hazards.
  2. Fire and Evacuation Hazards:
    • PV systems installed on roofs complicate firefighting due to ongoing electrical production.
    • DC cables routed through escape routes increase the risk during evacuations.
    • Cutting energized DC cables during emergencies increases the risk of severe injury or electrocution.
  3. Accountability and Liability:
    • Ambiguity regarding who holds legal responsibility during PV-related incidents.
    • Potential liability extends to building owners, system installers, maintenance contractors, and even first responders.
    • Negligence cases could arise if proper procedures, training, or PPE are not provided.

PVStop Overview:

PVStop is a polymer-based fire-retardant coating specifically designed for PV (photovoltaic) systems. It rapidly blocks sunlight, eliminating electricity generation from PV panels during emergencies, thus mitigating electrocution risks and enabling safe intervention.

Product Composition & Safety:

  • Composition: Water-based, containing proprietary non-hazardous polymer resins.
  • Safety Profile:
    • Non-hazardous according to Regulation (EU) 2015/830.
    • Low environmental impact; miscible in water.
    • Non-toxic, non-irritating, no special hazards, safe for general handling​.

Advantages in Emergency Situations:

  • Immediate Isolation: Quickly eliminates electrical hazards by physically blocking sunlight from reaching the PV cells.
  • Non-Electrical Solution: Unlike electrical rapid-shutdown devices (“fireman switches”), it doesn’t require complex electrical connections (MC4 connectors), thus eliminating additional points of failure.
  • Improves Firefighter Safety: Allows firefighters to safely approach PV systems without risk of electrical shock.
  • Certified and Compliant: Holds relevant certifications, including the EU-Type Examination Certificate (CE 603059), confirming its suitability for professional firefighting use​.

Legal and Safety Considerations for South Africa:

From a legal perspective, recommending PVStop as part of the safety protocol has several benefits:

Emergency Protocol Simplification: Easily incorporated into standard operating procedures without specialized electrical training, simplifying compliance and training. Safeguard lives, protect property, and reduce legal risks associated with photovoltaic system emergencies.

Legal Clarity: Using PVStop as a standard practice clearly demonstrates proactive risk mitigation, meeting regulatory compliance under OHSA, fire safety laws, and standards.

Insurance and Liability: Reduces legal liability exposure, as its deployment represents a demonstrable effort to mitigate electrical hazards effectively and safely.
