This Performance Engineer role is responsible for managing and optimizing the performance analytics of a portfolio of operating solar and battery assets to ensure they achieve expected energy output and operational excellence. The role focuses on monitoring and analyzing real-time and historical system data to identify underperformance, diagnose root causes, and drive corrective actions that optimize energy yield. A key objective is to prioritize and inform responses to alarms, repairs, and performance issues while maintaining a feedback loop between Engineering, Construction and Field Operations teams to address recurring or systemic challenges in the fleet. The position also supports the development of enhanced performance KPIs, reporting standards, and analytical tools, translating technical insights into actionable recommendations and business decisions. Ultimately, the role ensures continuous improvement of fleet performance through data-driven analysis, stakeholder collaboration, and targeted issue resolution.
Key Responsibilities
Performance Monitoring and Analysis
- Monitor real-time and historical performance of solar PV and battery systems using DAS, SCADA, telemetry, and analytics platforms
- Develop, maintain, and refine analytical tools that compare estimated performance models (with Assistance from Analytics team) against expected weather adjusted performance and actual performance.
- Aid in the definition of long-term performance KPIs : performance ratios, availability, capacity factor, energy loss breakdowns, degradation, system availability etc.
- Identify anomalies, trends, and deviations from expected performance; aid in the identification of root causes and the quantification of lost energy (soiling, shading, equipment degradation, inverter issues, AC / DC losses, MV issues, Grid events etc.)
