FAQ

TotalEnergies ENEOS follows stringent HSE standards based on its own global safety policies, local regulations and international norms for electrical and fire safety, designing commercial solar systems to meet or exceed national codes, utility requirements and recognised industry best practices.

Equipment testing ensures long-term safety and performance by subjecting solar panels, cables, connectors and junction boxes to fire rating tests, salt mist and corrosion tests, mechanical loading, weather and ageing tests, so only components proven to withstand real operating conditions are deployed on customer sites.

Fire prevention measures in commercial solar installations include the use of certified fire-safe PV modules and DC components, correct cable sizing and routing, protected junction boxes, proper overcurrent and surge protection, and installation methods aligned with strict fire-prevention standards used in TotalEnergies’ own industrial facilities.

TotalEnergies ENEOS ensures safe installation and on-site worker protection through rigorous contractor selection, mandatory HSE training, use of lifelines and fall protection, defined access paths and walkways on roofs, method statements and permits to work, and daily supervision by experienced site engineers.

Maintenance practices that help prevent performance loss or electrical risks include regular visual inspections, scheduled cleaning of modules, tightening and testing of electrical connections, thermographic scans to detect hot spots, performance monitoring against expected output and prompt corrective actions if anomalies are found.

Compliance with local and international electrical and fire codes is ensured by designing every solar power system to align with national standards, international IEC and NEC-type guidelines where applicable, utility interconnection rules and internal HSE checklists that are verified during design review, installation and commissioning.

Materials and components are selected for safety by prioritising PV modules, DC cables, connectors, junction boxes and mounting structures that carry recognised certifications, high fire ratings and proven track records in industrial environments, reducing the likelihood of overheating, arcing or mechanical failure.

Potential risks on roofs and industrial sites are assessed before installing solar panels through structural checks, load and wind assessments, review of roof condition, evaluation of access and evacuation routes, identification of existing services and hazards, and integration of these findings into the final system design.

24/7 monitoring helps detect safety or performance issues in a solar power system by continuously tracking generation, inverter alarms and string-level data, allowing the operations team to spot abnormal patterns, isolate affected components and dispatch maintenance teams quickly before minor issues become major faults.

In the event of a safety incident or system fault, a business can expect TotalEnergies ENEOS to follow a defined emergency response plan: safely isolate the affected part of the solar installation, investigate root causes, perform corrective repairs or replacements, document findings and update procedures to prevent recurrence.
