trough0ESAT (Enhanced Single Axis Tracking) is a unique calculation which finds the optimum angle of incidence at the lower solar elevations using the NREL equation. This improves efficiency in the winter months and is standard on all Tracker IPms.

With TLC (Temperature Limiting Control) and a Temperature Sensor, the Tracker IPm utilizes a Industrial Process Control PID loop to prevent over heating the temperature transfer medium by deflecting the tracker position. Efficiency is not lost since the loop can be tuned to maintain a set point of +/- 1 deg C.

Model Number: VT-IPM2M-113-SPA
