  • Equipment Selection, Inspection and Maintenance: Management of selection, inspection, testing and maintenance of cleaning tools, poles, pumps, harnesses, anchor points, ladders, EWP/MEWP and associated access equipment.
  • Health, Hygiene and Psychosocial Risk Management: Assessment of heat stress, dehydration, sun exposure, slips and trips, hygiene, fatigue, remote work isolation, and psychosocial risks such as work pressure and aggression at client sites.
  • Contractor and Subcontractor Management: Systems for prequalification, scope definition, competency verification, site induction, performance monitoring and integration of contractor SWMS and procedures with organisational controls.
  • Information, Documentation and Change Management: Controls for procedures, work instructions, permits, records, manufacturer guidance, and structured management of changes to equipment, systems, or work environments.
  • Emergency Preparedness and Incident Management: Planning for rescue from height, electrical shock response, first aid, spill response, communication systems, and incident reporting, investigation and corrective action processes.

Hazards & Risks Covered

Hazard Risk Description
1. Governance, WHS Duties and Legal Compliance
  • • Failure of officers and PCBUs to understand and discharge due diligence obligations under WHS Act 2011 in relation to solar panel cleaning activities
  • • Absence of a documented WHS management system specific to working at height and electrical risks associated with photovoltaic (PV) panel cleaning
  • • Inadequate consultation with workers and Health and Safety Representatives (HSRs) on solar cleaning methods, equipment and changes to processes
  • • Lack of formal processes to identify, assess and control new or changed risks arising from new rooftop configurations, inverters or cleaning technologies
  • • Inadequate contractor management framework for engaging third‑party solar cleaning providers or subcontractors
2. Design, Procurement and Installation of PV Systems and Access Infrastructure
  • • Solar PV systems designed or installed without consideration for safe access, egress and maintenance/cleaning requirements
  • • Procurement of PV panels, mounting systems and inverters without ensuring compatibility with safe cleaning methods (e.g. load rating, walkability, cleaning chemical limitations)
  • • Lack of engineered fall‑prevention and roof‑edge protection integrated into initial building or solar system design
  • • Inadequate documentation from installers regarding structural load limits, no‑step zones and fixing integrity for areas adjacent to panels
  • • Use of non‑compliant or poorly documented PV equipment sourced from suppliers without adequate technical and WHS information
3. Access, Working at Height and Fall‑Prevention Systems
  • • Inadequate or ad hoc systems for accessing roofs (ladders, access hatches, EWP use) during PV cleaning
  • • Absence or poor maintenance of permanent fall‑prevention systems such as guardrails, walkways, anchor points and static lines
  • • Unclear organisational rules regarding exclusion zones near roof edges, skylights and brittle roofing
  • • Lack of a systematic approach to verifying structural integrity of roofs used for access during cleaning activities
  • • No formal process for inspecting, maintaining and recertifying fall‑arrest equipment used by cleaners
4. Electrical Safety and PV System Isolation Management
  • • Inadequate systems for controlling electrical risks associated with live PV arrays that continue to generate DC under light
  • • Lack of clear organisational procedures for isolation, verification of de‑energisation and re‑energisation of PV systems prior to cleaning where practicable
  • • Insufficient delineation of roles between licensed electricians and cleaners regarding what electrical work is permitted
  • • Inconsistent lock‑out tag‑out practices for inverters, isolators and associated electrical equipment
  • • Failure to manage induced voltages, damaged wiring, or compromised insulation that may be exposed during cleaning activities
5. Water Quality, Chemical Use and Environmental Management
  • • Use of incompatible cleaning agents or untreated water that may damage PV panels, frames or wiring insulation over time
  • • Lack of controls for chemical storage, handling and disposal related to panel cleaning additives or detergents
  • • Environmental contamination from uncontrolled wastewater run‑off, particularly on large commercial roofs
  • • Inadequate assessment of slip hazards arising from water overspray, algae growth and residual detergents on access paths and ladders
  • • Absence of procedures for using demineralised water systems or filtration units that may operate under pressure
6. Competency, Training and Supervision
  • • Workers and contractors performing PV cleaning without adequate training in working at height, electrical awareness and PV system characteristics
  • • Inconsistent competency requirements across sites and contractors, leading to variable safety standards
  • • Lack of supervision or verification of competency for new or young workers involved in rooftop tasks

  • • No structured refresher training program to maintain competencies over time
7. Planning, Scheduling and Weather/Journey Management
  • • PV cleaning planned without adequate consideration of weather, temperature, wind and light conditions
