Photovoltaic panel assembly electric shock accident case

Was a worker electrocuted while installing solar panels?

During the solar panel installation, the worker noticed an exposed cable arcing and emitting smoke. PHOTO: BT FILE SINGAPORE – A worker died after being electrocuted while installing solar panels on the rooftop of a building on June 12 with a group of workers.

Are there occupational safety risks associated with solar PV installation?

An obstacle to solar PV growth is the severity of the occupational safety risks associated with their installation. Although PV installers are known to experience some of the most significant and widespread construction-related occupational safety risks, PV installer accident investigation research, reporting, and verification are limited.

What causes electrical shocks in a PV system?

Electrical shocks are typically caused by a short circuit resulting from corroded cables and connections, loose wiring, and improper grounding. Key places to look for these conditions in a PV system include the combiner box, PV source and output circuit conductors, and the equipment grounding conductor.

Are solar installers exposed to a fall accident?

Although there is a lack of formalized reporting and verification of solar worker fall accident data, it is clear that most residential and commercial solar installers are exposed to the risk factors clarified in the previous paragraph.

Are electrical and fire risks associated with PV installations?

The occurrence of electrical and fire risks can vary based on the type (e.g., rooftop, ground-mount), setting (e.g., residential, commercial, utility-scale), and weather conditions during PV installations.

Which safety risks are associated with PV installations?

Through reviewing these articles, four major safety risk categories were identified as being associated with PV installations: (1) electrical and fire risks, (2) heat stress, (3) manual handling risks, and (4) fall risks.
