Product Overview

Summary: This SOP sets out clear, practical requirements for the safe operation of vehicles and machinery on solar farms and rooftop solar sites. It helps organisations control the unique movement, electrical, and environmental risks of solar installations while maintaining productivity and compliance with Australian WHS laws.

Vehicle and machinery movements on solar sites present a complex risk profile that goes well beyond standard construction traffic management. Narrow access roads, fragile underground cabling, extensive PV arrays, glare, changing ground conditions, and mixed work groups operating in close proximity all increase the likelihood of collisions, rollovers, and plant–person interactions. This Safe Operating Procedure provides a structured, step‑by‑step system for planning, operating and supervising vehicles and machinery in and around solar installations, from initial mobilisation through to ongoing operations and maintenance.

Developed specifically for the Australian solar industry, this SOP helps businesses translate WHS obligations into practical controls that work in remote, regional and rooftop environments alike. It covers pre-start inspections, operator competencies, traffic management plans, exclusion zones around live electrical equipment, working near underground services, refuelling and maintenance, and emergency response. By implementing this procedure, organisations can demonstrate due diligence, reduce incident risk, and create consistent expectations for employees, contractors and subcontractors across all solar projects.

The document is designed to integrate with existing WHS management systems and contractor management processes. It provides clear responsibilities for PCBU representatives, site supervisors and plant operators, and includes guidance notes and prompts that can be adapted to the scale and complexity of each solar site. This ensures safer, more predictable operations while supporting on-time project delivery and reliable generation performance.

Key Benefits

• Reduce the risk of collisions, rollovers and plant–person interactions on solar farms and rooftop solar sites.
• Ensure vehicle and machinery operations align with Australian WHS legislation, electrical safety requirements and client specifications.
• Standardise pre-start checks, access controls and traffic management across all solar projects and contractors.
• Improve supervision and communication between plant operators, spotters, electricians and ground crews.
• Demonstrate due diligence to regulators, clients and insurers through a documented, defensible operating procedure.
