Fleet Performance Lead - Solar & Storage

SunStrong Management; United States; On-site; USD 130,000 - 190,000; Full time

Job summary

SunStrong Management seeks a Senior Performance Engineer to oversee energy performance across residential, commercial, community solar, and utility-scale assets. You will model production versus forecast, defend performance metrics, and coordinate with operations, O&M, and asset management on data quality, billing, and reporting.

You will help define data requirements, validate dashboards, and guide AI-enabled diagnostics while ensuring accurate settlement and investor reporting.

Qualifications

• Bachelor’s or Master’s degree in engineering, physics, or a related technical field.
• 8+ years in solar or storage performance engineering, asset performance management, or renewable O&M engineering, including 3+ years supporting commercial or utility-scale assets.
• Hands-on experience with PV performance modeling in PlantPredict (PVsyst or SAM acceptable as a secondary), and with satellite irradiance and weather datasets including Solcast, SolarAnywhere, and Open-Meteo.
• Working experience with fleet monitoring and asset performance platforms including AlsoEnergy, Power Factors, and 3E, including data extraction, tag mapping, and alarm configuration.
• Proficiency in SQL and in Python for engineering analysis (pandas, numpy, pvlib or equivalent).
• Practical fluency with AI tooling — coding assistants, LLM-based analysis, and agentic workflows — applied to engineering work, with sound judgment on where output must be verified.
• Demonstrated ability to specify data requirements, validation rules, and reconciliation logic for engineering and BI teams, and to review dashboards and reporting for correctness.
• Working knowledge of monitoring, metering, and SCADA data acquisition, including common protocols and vendor APIs (Modbus, SunSpec, DNP3, REST).
• Familiarity with leased, PPA, and securitized portfolios, including production and availability guarantees, settlement mechanics, and investor reporting obligations.
• Battery energy storage experience covering BMS behavior, state-of-health analysis, and dispatch validation.
• Ability to work against incomplete legacy as-built and monitoring data, and to state assumptions and uncertainty explicitly to engineering, asset management, and capital partners.

Responsibilities

• Model and monitor energy performance across residential, C&I, community solar, and utility-scale assets in PlantPredict and fleet monitoring platforms (AlsoEnergy, Power Factors, 3E).
• Calculate and defend contractual performance metrics including availability, performance ratio, production guarantees, and liquidated damages exposure, and support billing and reporting.
• Evaluate billing and settlement accuracy with asset management and O&M teams, reconciling metered and invoiced quantities.
• Investigate underperformance to root cause across inverters, meters, communications, energy storage, and site conditions, driving corrective actions.
• Direct the data requirements for fleet performance — tags, granularity, units, timestamps, quality rules — and support data collection and reconciliation.
• Advise on development of Power BI dashboards and performance reporting, defining metric definitions and acceptance criteria.
• Define monitoring, revenue-grade metering, and telemetry requirements for new sites and validate commissioning data.
• Establish performance baselines and data mappings for newly acquired portfolios; migrate from legacy monitoring platforms.
• Validate storage system performance against contracted operating modes and dispatch behavior.
• Apply AI tooling and agentic workflows to accelerate diagnostics and analytics, ensuring engineering verification where needed.
• Serve as technical reviewer for warranty claims and mentor junior engineers on performance methods.
