LTV Technologies & Supplies
Why We Entered the PV Risk and Safety Space
LTV Technologies & Supplies did not enter the PV safety field simply to promote individual products.
Our involvement developed through direct engagement with property owners, emergency responders, technical teams, schools, commercial facilities, insurers and people responsible for occupational health and safety.
We repeatedly encountered the same concern: rooftop solar was being installed and operated, but the responsibilities surrounding fire risk, emergency response, maintenance, evacuation, contractor safety and insurance were not always properly connected.
The electrical installer may understand the system design. The structural engineer may understand the roof. The fire consultant may understand the building’s conventional fire strategy. The facilities team may understand the operation of the site. The insurer may understand the policy wording.
But the complete PV risk often falls into the space between these different disciplines.
That is the gap LTV has been working to understand and help close.
Working with emergency responders
LTV Technologies & Supplies and Civitas Risk Control conducted a live PVSTOP proof-of-concept demonstration with the City of Tshwane Emergency Services at its Emergency Training Academy in Centurion.
The demonstration focused on the challenges emergency responders face when dealing with illuminated and potentially energised PV modules. It provided an opportunity for responders to observe practical light-blocking and PV de-energisation principles in a controlled environment.
The engagement, the public demonstration and the City’s letter of appreciation have already been documented and published. Public material relating to the event describes it as the first public deployment of PVSTOP in South Africa.
The purpose of this work is not to prescribe one response to every incident. It is to help emergency personnel understand the hazards, recognise the limitations of conventional isolation and make informed decisions based on the specific circumstances.
Supporting volunteer first responders
LTV has also supported members of VEMRU — Volunteer Emergency Medical Response Unit with access to PV safety and risk training.
Volunteer responders may arrive at incidents before municipal fire services or other specialist resources. They may be required to assess a scene, protect members of the public and decide how close it is safe to approach.
They therefore need to recognise:
- Rooftop PV installations.
- Potentially energised DC conductors.
- Damaged modules and cables.
- Electrical and fall hazards.
- Smoke, fire and structural risks.
- Areas that should not be entered.
- When specialist assistance is required.
This awareness helps first responders avoid unnecessary exposure and communicate more effectively with fire, medical and technical teams.
Learning from hospitals, production facilities and commercial sites
LTV has undertaken PV safety and preparedness work at a leading private hospital in Pretoria and at a commercial animal-feed production facility.
These environments demonstrate why PV risk cannot be considered only in terms of the solar equipment.
At a hospital, continuity of operations, vulnerable occupants, evacuation, emergency access and electrical resilience are critical.
At a production or warehouse facility, the exposure can include:
- Raw materials and packaged stock.
- Combustible materials.
- Machinery and production equipment.
- Employees and contractors.
- Smoke and water damage.
- Loss of production.
- Delayed customer orders.
- Extended business interruption.
The value at risk may be many times greater than the value of the PV installation itself.
For that reason, the assessment must consider the building, the people, the operation and the solar system together.
Schools and vulnerable occupants
LTV has visited schools and reviewed how rooftop solar interacts with existing emergency and evacuation arrangements.
Schools require particular care because they accommodate large numbers of children, teachers, support staff and visitors. A standard evacuation plan may not explain what to do during a PV-related electrical or rooftop incident.
Questions that should be addressed include:
- Do staff and fire wardens know that PV conductors may remain energised?
- Are roof access points and cable routes identified?
- Is there an emergency contact for the PV system?
- Can the system owner or developer be reached immediately?
- Is there authority to request shutdown or de-energisation?
- Are assembly areas safely positioned?
- Do emergency services have access to system information?
- Have staff practised the procedure?
We will refer to these engagements as work undertaken with schools in Pretoria and other educational facilities, rather than naming individual schools without written publication approval.
Training technical and operational personnel
LTV’s work has included awareness and practical training for:
- Fire representatives.
- Safety personnel.
- Facilities teams.
- Electricians.
- Millwrights.
- Maintenance teams.
- First responders.
- Operational decision-makers.
The objective is not to turn every employee into a solar technician.
It is to ensure that the relevant people understand:
- The difference between AC and PV DC hazards.
- Why daylight can keep parts of the system energised.
- What must not be disconnected or touched.
- How to recognise damage or a developing fault.
- How to report a near incident.
- Who has authority to shut the system down.
- When the workplace or roof should be declared unsafe.
- How to preserve records and evidence.
- How to support a safe evacuation and emergency response.
Cleaners and non-electrical contractors also need suitable induction. A contractor working on a roof should not be expected to identify PV hazards without being provided with information, access controls and site-specific instructions.
Moving from isolated documents to an auditable system
One of the most important lessons from our work is that preparedness must be provable.
After an incident, it may not be enough to say that maintenance was performed or that somebody verbally reported a concern.
The organisation should be able to produce:
- Risk assessments.
- Inspection reports.
- Thermal-scanning records.
- Maintenance certificates.
- Fault reports.
- Near-incident records.
- Photographs.
- Alarm and monitoring history.
- Contractor induction records.
- Training attendance.
- Emergency plans.
- Evacuation procedures.
- System maps.
- Corrective-action records.
- Proof that the insurer was informed.
This requirement has contributed to the development of the PVRX PV Risk Assessment and Readiness Platform.
PVRX is currently moving through demonstration and development stages toward production readiness. Its purpose is to help organisations assess risks, record evidence, allocate corrective actions and maintain a structured history of PV safety and readiness.
It is not intended to replace the engineer, fire consultant, electrician, insurer or OHS practitioner.
It is intended to help connect their work.
Practical evacuation and maintenance support
LTV has also developed a practical, entry-level PV evacuation-planning framework.
The initial format provides an affordable way for building owners and occupiers to begin documenting:
- Emergency contacts.
- System ownership.
- Isolation procedures.
- PV hazard areas.
- Roof and emergency access.
- Evacuation responsibilities.
- Staff and fire-warden instructions.
- Incident escalation.
- Communication with emergency services.
This framework will continue to develop into a more comprehensive digital and supported service.
Maintenance support is also available through structured system logbooks and SolarGrade-related inspection, fault-reporting and operations-and-maintenance processes.
The goal is to create a continuous record of the system’s condition, rather than relying only on occasional panel cleaning or informal contractor feedback.
Layered risk reduction
No single product can make a PV installation completely safe.
Effective protection may require a combination of:
- Independent PV risk assessment.
- Competent design and installation.
- Planned inspection and maintenance.
- Thermal scanning.
- Connector and cable-risk controls.
- DC connector encapsulation at appropriate connection points.
- Linear heat detection.
- AI-assisted smoke or heat detection.
- Clear signage and system mapping.
- Contractor induction.
- Staff and fire-warden training.
- Emergency and evacuation procedures.
- Light-blocking emergency-response capability.
- Appropriate lithium-ion fire-risk solutions where batteries are present.
- Suitable insurance and contractual arrangements.
LTV continues to assess early-detection technologies and works with specialist partners where risks fall outside our direct scope, including dedicated lithium-ion fire-risk specialists.
Our approach is to identify the risk first and then determine which controls are justified by the site.
Our role
LTV Technologies & Supplies is not a fire consultancy, structural engineering practice, electrical inspection authority or insurance brokerage.
Our role is to help property owners, tenants, developers, EPCs, facilities teams, insurers, emergency responders and professional consultants understand where their responsibilities meet — and where gaps may remain.
We focus on the interfaces between:
- PV technology.
- Fire safety.
- Occupational health and safety.
- Maintenance.
- Emergency response.
- Evacuation.
- Contractor management.
- Evidence and documentation.
- Insurance and liability.
Solar PV remains a valuable and necessary part of South Africa’s energy future.
Our aim is not to create fear around solar.
Our aim is to ensure that installations are not only efficient and compliant, but also properly assessed, maintained, documented and prepared for the unexpected.
Protect people. Protect property. Protect operations.
