Ground Mounted Solar Farm Construction Safety
Solar farm construction involves pile driving for mounting frames, manual handling of heavy panels, electrical installation of DC cabling, and working across large open sites in all weather conditions. The key electrical hazard is that solar panels generate DC voltage as soon as they are exposed to light and cannot be fully isolated during daylight hours. Understanding the specific risks of working with live DC systems and the logistics of large-scale open-site construction is essential for every operative.
- Treat all solar panels as electrically live during daylight hours and follow DC safety procedures.
- Use insulated tools and wear electrical safety gloves when making any DC cable connections.
- Cover panels with opaque sheeting during installation to reduce voltage generation where required.
- Use mechanical aids and team lifts for handling solar panels to reduce manual handling risk.
- Wear cut-resistant gloves when handling panels and mounting brackets with sharp metal edges.
- Provide hearing protection during pile driving operations for frame installation.
- Ensure all DC cabling is correctly labelled and routed to prevent damage from vehicles and plant.
- Brief all workers on the specific electrical risks of DC systems during the site induction.
- Ensure qualified electricians carry out all cable termination and inverter connection work.
If someone receives a DC electric shock, do not touch them until the circuit is broken. Cover the panel with an opaque material or disconnect the DC isolator. Call 999 and begin CPR if needed.
- Solar panels are live whenever daylight hits them and cannot be switched off like mains electricity.
- DC electric shock is particularly dangerous because the current does not naturally let go of the victim.
- Insulated tools and electrical safety gloves are mandatory for all DC connection work on site.
- Manual handling of panels is a major injury risk — use mechanical aids wherever possible.
- Pile driving for frame installation generates significant noise and vibration requiring PPE.
- Only qualified and authorised electricians should carry out cable termination and commissioning.
