A suitable risk assessment and safe system of work for a ground-mounted solar PV installation should be task-specific, site-specific, and reviewed as the work progresses. It should identify the jobs or tasks being done, the hazards workers are exposed to, where the hazards are located, the likelihood and severity of injury, and the controls required. The assessment should cover all phases of the work, include off-site and unusual conditions, consider visitors and the public, and take account of the knowledge, experience, training, and vulnerability of those doing the work, including young or inexperienced workers. [10] [5] [8]

Establish site induction, supervision, competence checks, welfare, first aid, traffic routes, exclusion zones, and daily briefings before work starts.
Confirm underground and overhead services, ground conditions, access/egress, weather exposure, public interfaces, and emergency arrangements.
Use the hierarchy of control: eliminate hazards where possible, then engineering controls, then administrative controls, and PPE last.
Stop work and review the RAMS if conditions change, such as severe weather, unstable ground, design changes, or unexpected buried services.

[3] [1] [5] For site hazards on ground-mounted PV projects, key risks typically include uneven ground, slips and trips, adverse weather, heat and UV exposure, mud, standing water, overhead work, stored materials, and interaction with the public or other contractors. Solar components can become hot in sunlight, and environmental conditions such as strong winds, rain, snow, or ice can significantly increase risk. Materials should be delivered, stored, and placed so they do not create trip hazards or unstable loading conditions, and areas below lifting or installation work should be protected from falling objects. [4] [4] [4] [4]

For excavation and trenching, the safe system of work should require a permit-to-dig, service drawings, cable/pipe locating, trial holes where needed, and clear segregation from plant. Excavations should be designed and inspected to prevent collapse, falls, flooding, and contact with buried services. Spoil, materials, and plant should be kept back from edges; safe access and egress provided; and no one should enter an unsupported trench where collapse is possible. Ground conditions and weather should be reassessed daily and after heavy rain. Because trenching for DC strings, AC cables, and earthing often occurs alongside moving plant, the excavation zone should be barriered and controlled by a supervisor or appointed person.

Manual handling risks are significant during unloading, carrying posts, rails, cable drums, ballast, and PV modules. The assessment should identify ergonomic hazards such as heavy lifting, repetitive movements, and awkward postures, then reduce them by mechanical aids, team lifts, route planning, limiting carry distances, and staging materials close to the point of use. Panels should be handled in a way that prevents sudden wind loading, twisting, and hand injuries. [6] [5] [15]

Lifting operations for piles, frames, inverters, transformers, cable drums, and palletised modules should be planned and supervised, with suitable lifting equipment, verified ground bearing capacity, exclusion zones, and competent operators, slingers, and signallers. Loads should be stable, correctly rigged, and protected against pinch points. Deliveries and crane or telehandler operations should be coordinated so that landing areas are clear and workers are not beneath suspended loads. [4] [2]

Working at height may still arise on ground-mounted projects during inverter installation, cable tray work, lighting column work, temporary access to containers or kiosks, and loading/unloading. The safe system should apply the hierarchy of control: avoid work at height where possible, use suitable work equipment such as podiums, towers, or MEWPs where justified, and only use ladders for short-duration, low-risk tasks. Where there is exposure to an unguarded edge or fall risk, a fall protection plan, rescue arrangements, training, and suitable fall protection equipment are required. [3] [13] [4]

Electrical safety is critical because PV modules generate electricity whenever exposed to light. The system of work should therefore minimise live working, sequence installation to reduce exposed live DC parts, use shrouding or covering where appropriate, maintain polarity checks, and ensure only competent electrical workers carry out testing, termination, commissioning, and fault-finding. Isolation procedures should include lockout/tagout, proving dead with properly rated test equipment, maintaining safe boundaries, and controlling access to energised equipment. The best protection is to de-energise equipment before work; energized work should be exceptional and justified. [4] [17] [17] [11]

Plant and vehicle movement should be controlled through a traffic management plan covering delivery vehicles, excavators, dumpers, telehandlers, cranes, and MEWPs. Separate pedestrian and vehicle routes where possible, use one-way systems and banksmen where visibility is restricted, enforce speed limits, and define loading, unloading, and reversing arrangements. Interface risks increase in congested areas and where excavation, lifting, and public access overlap, so exclusion zones and communication protocols are essential. [5] [6]

PPE should be selected from the hazard assessment and should not be the first control measure. Typical PPE for ground-mounted solar PV installation includes safety helmet, eye protection, gloves suited to the task, high-visibility clothing, safety footwear with suitable sole protection and slip resistance, hearing protection where noise assessment requires it, weather protection, and fall protection or electrically rated PPE where the task demands it. Head, hand, foot, eye, hearing, and fall protection all need to be matched to the identified hazards and documented. [1] [8] [2] [12] [14] [16]

Emergency procedures should be written into the safe system of work and briefed to all workers. They should cover first aid, fire, electric shock, arc flash, trench collapse, plant collision, severe weather, and rescue from height where relevant. Emergency contacts, site address details, access points, grid references if remote, and arrangements for contacting emergency services should be available. Workers should understand the alarm and stop-work arrangements, and supervisors should be prepared to implement emergency response procedures immediately. [3] [17] [5]

In UK practice, compliance should be structured around the Health and Safety at Work etc. Act 1974, the Management of Health and Safety at Work Regulations 1999, CDM Regulations 2015, Work at Height Regulations 2005, PUWER, LOLER, Electricity at Work Regulations 1989, PPE at Work Regulations, Manual Handling Operations Regulations 1992, and HSE guidance such as HSG47 for avoiding danger from underground services, HSG150 for construction health and safety, HSG85 for electricity at work, and relevant HSE guidance on excavations, traffic management, and lifting operations. Under CDM, dutyholders should ensure suitable arrangements for planning, managing, monitoring, coordination, competence, welfare, and cooperation; construction phase plans and RAMS should reflect the significant risks and controls for the solar PV works.

Prepare a site-specific RAMS package before work starts and brief it at induction and daily task briefings.
Use permits for excavation, electrical isolation, and lifting operations where risk justifies formal control.
Ensure competent supervision for civil, mechanical, and electrical phases, with clear hold points for inspection and testing.
Inspect plant, lifting accessories, access equipment, PPE, and temporary works before use and at required intervals.
Suspend work in unsafe weather such as lightning, high winds, extreme heat, snow, or flooding.
Maintain records of hazard assessments, inspections, training, briefings, and incidents, and review controls after changes or near misses.
