Product Overview

Summary: This Electrical Safety for Solar Installations SOP sets out clear, practical steps for planning, installing, testing and maintaining solar PV systems safely in Australian workplaces. It helps your team control electrical and working-at-heights risks, align with WHS duties, and deliver compliant solar projects without compromising worker safety or system quality.

Solar installations combine conventional electrical hazards with rooftop and structural risks, often in dynamic construction environments. Without a structured approach, workers can be exposed to live DC and AC components, arc flash, falls from height, and unsafe isolation practices, particularly during installation, commissioning, maintenance and fault-finding. This Electrical Safety for Solar Installations SOP provides a detailed, step-by-step framework to manage those risks from pre-start planning through to handover and ongoing service.

Developed for the Australian solar and construction sectors, the procedure sets out how to conduct electrical risk assessments, implement lock‑out/tag‑out (LOTO), manage live parts, and coordinate with other trades on site. It supports compliance with WHS legislation, electrical safety regulations and relevant Australian Standards, while also lifting the professionalism and consistency of your solar operations. By adopting this SOP, businesses can confidently demonstrate due diligence, reduce the likelihood of electrical incidents and near misses, and give workers clear, practical guidance they can follow on every job.

Key Benefits

• Ensure compliance with Australian WHS and electrical safety requirements for solar PV installations.

• Improve installation quality and commissioning reliability through structured testing and verification steps.
• Streamline training and onboarding of new solar electricians and installers with clear, task-based procedures.
• Demonstrate due diligence to clients, regulators and insurers with documented, repeatable electrical safety controls.
