The rate of solar photovoltaic (PV) installations in Australia is booming. This is great news for businesses and installers but also means hectic schedules, pressure on install times and lots
When working and operating any PV system, the safeguards described below should be heeded. The best safety method is an alert mind, a doubting nature, and a slow hand. Never work on a PV installation alone. Know the PV and associated electrical system before you start to perform work. Discuss the test goals and methods with your partner.
Solar PV systems can provide power during the night or when there is a problem with the bank of batteries. For optimal safety, firefighters should use a standardized approach when working around solar PV systems in off-grid situations.
Solar PV systems should be isolated at any time of day or night for safety. (...)For overall safety, ALL PV systems should be isolated(...) before working around the system. SECTION 6. The general hazards that exist for solar PV on residential or commercial structures are not strictly specific to PV technology. The same hazards exist with traditional electrical systems.
This report also addresses currently known major safety requirements during PV servicing and repair, including the proper use of lockout/tagout procedures, the use of personal protective equipment, procedures for safely disconnecting live circuits, and appropriate observation of and compliance with all PV-specific system signage and warnings.
A recommended safety protocol is to follow the left hand rule, which involves standing to the right side of the switch and using the left hand to throw the switch. This ensures that the worker’s body is not in front of the switch should an arc flash occur. PV System Operations and Maintenance Fundamentals11

Vegetation Management Vegetation management is particularly important in ground mount systems, but is a concern for all PV systems.
