Key Features

Embedded intelligence for every tracker.

Cutting-edge Brazilian technology to maximize generation and simplify operations at solar plants with tracking systems.

AI Technology

TrackBoost AI that thinks beyond the sun.

On cloudy days, diffuse radiation outpaces direct radiation — and the astronomical algorithm loses efficiency. TrackBoost uses embedded machine learning to compute the optimal angle in any atmospheric condition.

Inputs

Irradiance (pyranometer)
Wind Speed
Date and Time
Latitude & Longitude

Model

Embedded AI

Lightweight machine learning processed in real time on the TCU hardware.

Output

Optimal Angle
Energy Gain
ROI Improvement

+1.74%

average energy gain over the astronomical algorithm across the full test period

+13.68%

peak gain recorded in a single high-cloud-cover day

< 3 years
