Job description

As an O&M Engineer, you will own the day-to-day technical performance, safety and reliability of the sites assigned to you, ensuring they meet contractual availability and performance guarantees while keeping lifecycle cost under control. You will work with a diverse cross-functional team within the organisation on different tasks which can cultivate your adaptability skills.

Key responsibilities

Monitoring and Performance Analysis

Oversee the real-time health of assigned plants through SCADA, inverter portals, data loggers and monitoring platforms; triage alarms by severity and ensure timely response within agreed SLAs.

Analyze performance data to identify trends, inefficiencies, and potential issues. Generate reports on plant performance, energy output, and system health.

Preventive and Corrective Maintenance

Develop, schedule and supervise preventive maintenance (PM) programmes for PV modules, DC/AC cabling, combiner boxes, inverters, MV/LV switchgear, transformers, protection relays, earthing and lightning protection, and monitoring equipment.

Lead condition-based inspections using drone aerial thermography, handheld IR cameras, I-V curve tracing, insulation resistance and other diagnostic tools; interpret results and prioritise remedial work.

Lead fault diagnosis and structured root cause analysis (RCA) for inverter trips, ground faults, hotspots, string failures, tracker or communication faults and grid-related events; implement corrective actions and verify results.

Manage O&M technicians and subcontractors on site, including work planning, method statements, quality checks and handover.

Coordinate cleaning programmes and optimise cleaning frequency using soiling data and rainfall patterns to balance yield gain against cost.

System Optimization

Identify and implement performance improvement initiatives such as string re‑configuration, inverter parameter tuning, vegetation management, drainage and civil rectification, and module or inverter repowering.

Manage warranty and defect claims with OEMs and EPC contractors (modules, inverters, trackers, transformers), including evidence gathering, technical submissions and follow‑up to closure.

Plan and execute component replacement and upgrades, including technical specification review, vendor comparison and commissioning verification.

Support the evaluation of retrofit opportunities such as battery energy storage systems (BESS), EV charging integration, advanced monitoring and tracker or optimiser upgrades.

Monitor ageing, degradation trends and end‑of‑warranty risks, and contribute to long‑term asset management plans.

Safety Compliance

Ensure that all O&M activities comply with relevant safety standards and regulations.

Conduct safety inspections and risk assessments to identify and mitigate potential hazards.

Develop and execute emergency response plans in case of system failures or safety incidents.

Maintain detailed records of all O&M activities, system performance, and incidents.

Prepare and submit regular O&M reports to management on plant performance, maintenance activities, and any issues encountered.

Team Coordination and Management

Supervise and coordinate the work of O&M technicians and other staff involved in the maintenance activities.

Provide training to junior staff or technicians on proper maintenance procedures and safety practices.

Client and Stakeholder Interaction

Work closely with clients to address their concerns, provide updates on plant performance, and ensure customer satisfaction.

Provide technical support to clients or stakeholders, including explaining technical aspects and resolving queries related to the operation of the solar power plant.

Budget and Inventory Management

Manage the O&M budget, including controlling costs for repairs, replacements, and routine maintenance.

Monitor and manage the inventory of spare parts, tools, and other resources necessary for maintenance activities.

Regulatory Compliance

Ensure that the plant complies with all regulatory requirements, including obtaining and maintaining necessary permits and certifications.

Monitor and manage environmental impacts, ensuring the plant operates within legal environmental guidelines.

Explore new technologies, tools, and methods to improve the efficiency and effectiveness of O&M activities.

Provide feedback to the design and installation teams to help improve future solar power projects based on O&M experiences.

Others: Ad hoc projects when required by management.
