Solar PV technicians specialize in operations and maintenance (O&M) of installed solar systems. Their responsibilities include inspecting panels, checking connections, diagnosing electrical faults, monitoring system performance, performing cleaning, ensuring inverter uptime, and maintaining logs. They work across rooftop, industrial, and utility-scale solar installations. As energy transition policies expand, O&M roles are becoming more critical for sustaining production reliability. Technicians increasingly use digital monitoring platforms, IV-curve testing tools, and predictive analytics. Strong technical accuracy, safety adherence, and problem-solving are essential. Demand is rapidly growing worldwide due to large-scale solar adoption and long-term service requirements.
