Thermal Imaging and I-V Curve Testing

Engineering Design Services provided comprehensive performance evaluation services for a utility-scale solar farm located in Central Texas using advanced drone-based thermal imaging and on-site I-V curve testing. The objective of the project was to identify underperforming assets, verify system health, and support proactive maintenance planning to maximize energy output.

​

EDS deployed unmanned aerial systems equipped with high-resolution thermal cameras to survey photovoltaic modules across the site. The aerial thermal inspection allowed for rapid identification of anomalies such as hot spots, faulty connections, damaged modules, and inverter-related issues without disrupting ongoing operations. Collected imagery was analyzed and compiled into actionable reports, enabling targeted corrective actions.

​

In parallel, EDS performed I-V curve testing on selected strings and modules to validate electrical performance against expected design parameters. This testing provided detailed insight into degradation, shading impacts, and balance-of-system issues that may not be visible through thermal data alone.

​

By combining drone-based thermal imaging with I-V curve testing, EDS delivered a comprehensive assessment of system performance. The results supported informed decision-making for operations and maintenance teams, improved system reliability, and helped the client optimize long-term solar asset performance.
