Solar farm work needs a coordinated WHS system that covers the whole job—from design and civil works through commissioning, operation, maintenance and eventual decommissioning. For crews, that means the hazards, controls, responsibilities and emergency arrangements should be clear before work starts and kept current as the site changes.
Queensland's Construction and operation of solar farms Code of Practice 2024 is the main official reference for this topic in Queensland. Local requirements vary across Australia, so always check the current regulator material for the place where the work is done. National Model Codes can provide general orientation, but they do not automatically apply as law.

Main hazards on solar farms
Solar farms combine construction, electrical and operational risks across a large work area. Common hazards include:
- DC and AC electrical risks, arc flash, earthing faults and stored or generated energy
- mobile plant, cranes, delivery vehicles and workers on foot
- falling panels, frames, loads or other objects
- manual handling and repeated lifting during panel installation
- falls, slips, trips, excavations and uneven ground
- heat, sun, noise, dust, storms, high winds and fire
- remote or isolated work, fatigue and delayed emergency assistance
- damaged modules, hazardous substances, batteries, fuels, vegetation and wildlife.
The risk picture changes during the project. A section being built may sit beside an energised or operating section, while commissioning introduces new boundaries and access restrictions. Clear separation, controlled access and reliable communication are essential.
What to sort out before work starts
Planning should be based on the actual site, work sequence and contractor interfaces. Before mobilisation or a new stage, confirm:
- who controls each work area and who can authorise changes
- access routes, delivery areas, pedestrian separation and exclusion zones
- electrical status, isolation points, test boundaries and energisation stages
- underground and overhead services, ground conditions and excavation controls
- plant selection, lifting arrangements and competent operators
- heat, weather, fire, first aid, rescue and emergency arrangements
- worker consultation, supervision, training and communication methods
- how incidents, defects and changes will be reported, reviewed and closed out.
Safe design matters too. Decisions about layout, drainage, cable routing, access, equipment, maintenance space and future removal can eliminate risks before they reach the crew.
What good controls and documents usually cover
Good controls follow the hierarchy of control. Eliminate the hazard where reasonably practicable. Where that cannot be done, use the strongest workable controls before relying on procedures and PPE. Controls also need to be maintained, checked and revised when conditions change.
A practical site system may include a WHS management plan where required, risk assessments, SWMS, traffic management plan, lift plans, electrical isolation or switching procedures, permits, emergency and rescue plans, inspection schedules, pre-start records, training records and corrective-action tracking.
The documents should match each other and the work. A traffic plan is not useful if the induction shows different routes. An isolation procedure should reflect the current single-line diagram and commissioning stage. Design and asset information should be accessible, controlled and updated when new information or changes arise.
During operation and maintenance, the safety management system should cover access, competencies, isolation and switching, vegetation, inspections, fault response, emergency arrangements, consultation and review. Maintenance frequency should account for manufacturer instructions, site conditions, faults and previous inspection results.
When a SWMS or another site-specific document applies
In Queensland, a SWMS must be prepared and followed for high risk construction work. Powered mobile plant used during solar farm construction is one clear example identified in the Code. Other tasks may also meet the high risk construction work definition, so check the actual method and current jurisdictional rules before starting.
A useful SWMS is site and task specific. Workers should understand the hazards, apply the stated controls and know what to do if the work no longer matches the SWMS. Review it before work continues when plant, access, sequencing, boundaries, weather or another critical condition changes.
A task may also need a traffic plan, lift plan, permit, switching program, isolation procedure, rescue plan, job safety analysis or manufacturer-based instruction. Choose documents to control the real interfaces rather than adding paperwork for its own sake.
Practical warning signs
Stop and reassess when:
- crews cannot explain the exclusion zone, isolation or emergency process
- the SWMS names different plant or methods from those onsite
- vehicles and pedestrians mix without effective separation
- energised and construction areas are not clearly delineated
- high winds, heat or storms exceed the planned conditions
- drawings, cable locations or trenches do not match the site
- multiple contractors assume someone else owns the risk
- defects or near misses are recorded but actions remain open.
These are signs the work system needs attention, not merely document issues.
How Blue Safe helps
Blue Safe provides compliant WHS documents tailored to the client's activities, applicable Australian WHS/OHS requirements, jurisdiction and industry. These can include SWMS, WHS management plans, risk assessments, procedures, registers, forms and supporting site documents matched to the work.
Blue Safe guarantees the document compliance of the WHS documents it provides, including eligible customer documents after Blue Safe has reviewed and upgraded them. Customers actively put the compliant documents into practice through controls, consultation, training, actions, records and evidence. This keeps the written system connected to supervision and day-to-day work.
