Orion Solar Racking designs Single Axis Solar Trackers that are developed with hybrid light sensing controller. It constantly checks differential signals from a pair of light sensors, and drives the tracker to maximize solar energy collected. When it is cloudy, light sensing mode will be put on idle, while timing control takes in charge, allowing the tracker to continue moving from East to West. Single Axis Solar Trackers include the following features: Up To 40% More Production Than Fixed Racking System Low Maintenance Great Warranty On Electrical Components Best For Large Solar Farm Project Ease Of Installation Superior Value
