Parallel skill requirements and training needs for wind and solar

As the renewable energy sector grows at a rapid pace, the demand for skilled workers in wind and solar energy industries has risen significantly. While these industries share many overlapping skill sets and safety concerns, they also have distinct requirements that reflect the unique nature of their operations. A well-trained workforce is essential for ensuring safety, efficiency, and reliability in both sectors, and various specialized courses like the GWO Control of Hazardous Energies, QEW NFPA 70E, BOP Substation, and PMT Switching courses offered by STL USA provide crucial training tailored to the needs of these industries. This article examines the core skills, training requirements, and specific overlaps in competencies needed by wind and solar energy workers.

Key Skills and Challenges in Wind and Solar Energy

Both wind and solar energy workers must be adept at handling complex electrical systems and work in hazardous environments. A foundational understanding of electrical theory, and mechanical systems is critical for both sectors. However, each industry also requires specialized skills due to differences in infrastructure and operations.

• Wind Energy: Workers in this sector often need to scale wind turbines that can reach heights of over 100 meters. This demands proficiency in fall protection, and working at heights. Additionally, turbine maintenance involves knowledge of mechanical and electrical systems, major component maintenance, and composites.

• Solar Energy: Solar workers, in contrast, focus more on ground-level tasks such as installing and maintaining photovoltaic (PV) panels, troubleshooting inverters, and optimizing system performance.

Despite these differences, both industries face common hazards, such as electrical shock arc flashes and require robust electrical safety programs. Specialized training courses address these hazards and ensure workers meet safety and operational standards.

Training Overlaps and Industry-Specific Needs

The GWO Control of Hazardous Energies, QEW NFPA 70E, BOP Substation, and PMT Switching courses offered by STL USA are particularly relevant for preparing workers for the challenges in both wind and solar industries. Below is an overview of the critical aspects of these courses and their applications.

1. GWO Control of Hazardous Energies

   • This course, designed by the Global Wind Organization (GWO), focuses on identifying and controlling hazardous energies during installation, maintenance, and decommissioning of energy systems. Workers learn lockout/tagout (LOTO) procedures, risk assessment, and energy isolation techniques.

   • Applications in Wind Energy: The course is crucial for turbine technicians who need to safely manage the high-voltage systems within wind turbines. Turbine systems often involve multiple energy sources, such as hydraulic, mechanical, and electrical, making LOTO procedures essential.

   • Applications in Solar Energy: While solar systems involve less moving mechanical energy, the principles of hazardous energy control apply equally to PV systems—especially during inverter maintenance and troubleshooting.

2. QEW NFPA 70E

   • This course focuses on electrical safety in line with NFPA 70E standards. Participants learn about arc flash hazards, shock protection, and the use of personal protective equipment (PPE).

   • Applications in Wind Energy: Wind technicians benefit from this course when working with high-voltage switchgear and performing electrical maintenance inside turbine nacelles. Arc flash hazards are a significant risk in such confined spaces.

   • Applications in Solar Energy: Solar electricians require this training to safely handle PV systems and manage the risks associated with arc flashes during panel installation, inverter maintenance, and string troubleshooting.

3. BOP Substation Training

   • The Basic Balance of Plant (BOP) Substation training introduces workers to the equipment, terminology and overview function of BOP — key components in connecting renewable energy systems to the grid.

   • Applications in Wind Energy: Wind farms typically rely on substations to transmit power to the grid. Workers must understand transformer operations, relay protection, and switchgear maintenance.

   • Applications in Solar Energy: Similarly, solar farms depend on substations for grid integration. Workers trained in substation operations ensure the seamless transfer of energy from PV arrays to utility lines.

4. PMT Switching

   • This course provides training in safe switching operations and the isolation of equipment for maintenance.

   • Applications in Wind Energy: Turbine technicians often perform switching operations to isolate turbines or other equipment for repairs. This course ensures they can do so safely and efficiently.

   • Applications in Solar Energy: Solar energy workers use similar skills when isolating strings or inverters for repairs or upgrades, particularly in large-scale solar farms.

GWO Basic Safety Training: Transferable Skills Across Sectors

The GWO Basic Safety Training (BST) course is a foundational program designed to prepare workers for the general hazards encountered in wind energy environments. However, several modules within the course provide transferable skills that are highly applicable to the solar energy sector and other industries.

• First Aid Module: This module equips workers with life-saving techniques and emergency response skills, which are universally applicable across industries. Whether responding to accidents in a wind turbine or a solar farm, these skills are critical for ensuring worker safety.

• Fire Awareness Module: This module teaches workers how to identify fire risks, use fire extinguishers, and evacuate safely. Solar farms and rooftop installations can also face fire hazards, making this training valuable for solar technicians.

• Manual Handling Module: Workers are trained in safe lifting and handling techniques to reduce the risk of musculoskeletal injuries. This is a key competency in both wind and solar sectors, where workers frequently handle heavy or awkwardly shaped components like turbine parts or PV panels.

These transferable elements make the GWO Basic Safety Training course an excellent entry point for workers seeking to move between wind and solar energy roles or diversify their skill sets for broader opportunities within the renewable energy sector.

Overlapping Competencies: Building a Versatile Workforce

The training and skills required for wind and solar energy workers often intersect in areas such as electrical safety, energy isolation, and substation maintenance. Workers who complete courses like GWO Control of Hazardous Energies and QEW NFPA 70E gain competencies that are transferable between the two industries, providing flexibility in a rapidly evolving job market.

• Electrical Safety: Understanding shock protection and arc flash protection, PPE and equipment selection is indispensable in both sectors.

• Energy Isolation: Establishing an electrically safe work condition and safe work procedures taught in the GWO CoHE and QEW NFPA 70E are critical for preventing accidents during maintenance in both wind and solar environments.

• Substation Skills: With many renewable projects relying on substations, our Basic Balance of Plant Training teaches safe substation entry, equipment familiarization, high and medium voltage protection principles, introduction to high and medium voltage schematics including relay, ANSI and IEE naming conventions.

Conclusion

The wind and solar energy industries share a common goal: harnessing renewable resources to produce clean energy. While their operational differences necessitate specific skill sets, overlapping competencies in areas such as electrical safety, hazardous energy control, and substation maintenance highlight the value of cross-industry training. By participating in courses like GWO Control of Hazardous Energies, QEW NFPA 70E, BOP Substation, and PMT Switching, workers can not only enhance their expertise but also adapt to the evolving demands of the renewable energy sector. Investing in such training is not just about compliance—it’s about building a skilled workforce capable of advancing the global transition to sustainable energy.
