TerraTrak AI Solar Tracking System
Building AI + SCADA-connected tracking intelligence that improves solar yield by 15% while lowering downtime—paired with structural engineering collaboration.
The Challenge
Solar trackers relied on static algorithms that couldn't adapt to real-time weather changes, resulting in suboptimal panel angles, mechanical stress, and lost energy yield. Operators lacked fleet-level visibility into tracker health.
What We Built
Zigron delivered a complete AI + IoT solution: an autonomous decision-support engine fusing tracker telemetry with weather and inverter data, embedded IoT SDKs on controllers, bidirectional SCADA communication, and a central dashboard for fleet visualization.
The Results
Energy capture efficiency increased 15%, mechanical failure and downtime dropped 20%, and sub-minute alignment adjustments became possible in dynamic weather. Material usage was reduced 20% through structural optimization.
Context & Complexity
Solar tracker systems operate in extreme environments where weather conditions change rapidly. Static tracking algorithms miss significant energy capture opportunities and cause unnecessary mechanical wear on tracker components.
The challenge required deep integration across multiple domains: AI/ML for optimization, industrial IoT for controller communication, SCADA for command and control, and structural/mechanical engineering for load analysis and response tuning.
The system needed to be reliable enough for unmanned solar sites. Faults in tracking logic could damage equipment or cause safety events, requiring rigorous validation and fail-safe design across the entire stack.

Engineering Approach
The AI engine fuses three data streams—tracker sensor telemetry, weather/irradiance data, and inverter output—to compute optimal alignment in real-time. Controllers run embedded IoT SDKs communicating via Modbus RTU and MQTT. The SCADA layer enables bidirectional commands with fail-safe logic, while the structural team integrated geotechnical modeling and wind-tunnel analysis to optimize mechanical response.
