Solar SWMS — Safe Work Method Statement for Solar Panel Installation

Solar photovoltaic installation is one of the highest-risk combinations of trades on a construction site because it simultaneously triggers multiple high-risk construction work (HRCW) categories under WHS Regulation 2025 Schedule 1. Every installation involves work above 2 metres (falls category), work on or near energised electrical installations (electrical category), and frequently work involving powered mobile plant (where an EWP or truck-mounted platform is used for commercial installations). A Safe Work Method Statement is therefore legally required before any solar installation work commences, regardless of whether the system is a 6.6 kW residential array or a 100 kW commercial array.

Legal Requirements

WHS Regulation 2025 Part 6.1 Division 3 — High Risk Construction Work; WHS Regulation 2025 Part 4.7 — Electrical Safety

hrcw category

Work involving a risk of a person falling more than 2 metres; work on or near energised electrical installations or services; work involving powered mobile plant (where an EWP is used). Multiple HRCW categories apply simultaneously (WHS Regulation 2025 Schedule 1).

Hazards

HazardConsequenceLikelihood
Falls from roof edge during panel positioning, mounting, and cable routingFalls from height are the leading cause of death and serious injury in Australian construction.Possible (C)
DC electric shock from solar string voltage during wiring, connection, and fault-findingSolar strings produce DC voltage whenever exposed to light.Possible (C)
DC arc flash during cable cutting, plug disconnection, or insulation failureDC arcs do not self-extinguish because the voltage does not cross zero.Unlikely (D)
Falls through fragile roof surfaces including skylights, deteriorated fibre cement cladding, and aged metal sheetingFalling through a fragile roof panel results in an internal fall to the level below, often striking structural members on the way.Possible (C) on older commercial roofs; Unlikely (D) on modern residential roofs with trussed roof framing
Heat stress from working on hot roof surfaces during summerMetal roof surfaces routinely exceed 65 degrees Celsius in Australian summer conditions and can approach 75 degrees Celsius in direct sun.Likely (B) during summer months on unshaded roofs
Manual handling of solar panels on pitched and sloped surfacesStandard solar panels weigh 20 to 25 kilograms each and are awkward to carry on pitched roofs.Likely (B)
Cable routing through ceiling voids and wall cavitiesDC and AC cables must be routed from the rooftop array down to the inverter and switchboard, which almost always involves work in the ceiling space.Possible (C)
Structural overloading of roof from panel array weightA typical residential solar array with mounting rails adds 15 to 25 kilograms per square metre to the roof dead load.Unlikely (D)
Contact with overhead power lines during panel transport and crane operationsPanels being lifted from truck to roof, or moved across a rooftop, can contact overhead power lines at the service entry or nearby street distribution network.Unlikely (D)
UV radiation exposure during extended rooftop workExtended rooftop work in Australian conditions causes severe sunburn, cumulative skin damage, and long-term skin cancer risk.Almost Certain (A) on unprotected workers during daylight work

Controls (Hierarchy of Controls)

[Elimination] Specify off-site pre-assembly of mounting rails and cable harnesses wherever practicable to reduce on-roof time
[Elimination] Schedule installations for early morning or late afternoon in summer months to reduce heat stress exposure and surface temperature
[Substitution] Substitute DC optimisers or microinverters for string inverters on commercial systems where practicable to reduce string voltage and DC arc risk at the module level
[Substitution] Use pre-crimped, factory-tested MC4 connectors rather than field crimping to eliminate the primary failure mode for DC arc flash
[Isolation] Install edge protection guardrails to AS/NZS 4994.1 around the full working perimeter before any roof access; guardrails include top rail minimum 900 mm, mid-rail, and toeboard
[Isolation] Install DC isolator switches at the array, at the inverter, and at the switchboard to AS/NZS 5033 so that string voltage can be removed from the circuit before any work on DC wiring
[Isolation] Establish exclusion zone at ground level below the work area using physical barriers and warning signs; no worker or member of the public permitted below the active work area
[Engineering] Structural assessment of roof capacity by a Chartered Professional Engineer for commercial installations and for any residential installation on a pre-1990 building, confirming the roof can support the combined dead and live load per AS 1170.1
[Engineering] DC-rated load-break isolators, anti-arc MC4 connectors, and correctly torqued terminations per manufacturer specification — never cut DC cables under load
[Engineering] Use mechanical material hoists, telehandlers, or cranes for panel lifting to the roof rather than manual handling up ladders

Recent Prosecutions

Clean Energy Regulator enforcement activity — solar PV installers (2020-2024)Accreditation suspension and cancellation

The Clean Energy Regulator has investigated and enforced against multiple solar PV installation businesses over the period 2020 to 2024 following reports of non-compliant installations, DC electrical incidents, and rooftop fires. Enforcement outcomes have included accreditation suspension, cancellation, and in some cases referral to state electrical safety regulators. Common findings included inadequate DC isolation procedures, poor MC4 connector crimping, and missing or inadequate site-specific SWMS.

2024 — Clean Energy Regulator enforcement and compliance reports

SafeWork NSW solar installation enforcementImprovement and prohibition notices

SafeWork NSW has conducted targeted enforcement on solar PV installation sites, issuing improvement and prohibition notices for work at heights without edge protection, work on live DC systems without DC-rated isolation, and missing site-specific SWMS. Inspectors have cited the Code of Practice: Managing the Risk of Falls at Workplaces and the Code of Practice: Managing Electrical Risks in the Workplace.
