Arctech tracking controller systems utilize proprietary algorithm strategies to track the sun. During normal operation, each controller determines the optimal tracker position angle, considering adjacent tracker positions, time of day, and real-time data from the central NCU, such as weather sensor information.
When weather conditions deteriorate, these operational strategies can be adjusted at any time. To protect the structural integrity of the tracker and PV modules, normal tracking operations may be halted, and a specialized weather protection mode activated. This mode can be enabled automatically or manually via remote commands through SCADA or by a local operator.
Arctech's wind protection logic halts trackers at a 2° wind-facing position when wind speed exceeds a predefined threshold.
Floods can damage PV modules and equipment. Sensors monitor water levels, enabling tracker controllers to adjust positions for protection.
Hail can damage PV modules and reduce power output. Hail mode adjusts tracker angles to minimize impact and mitigate risk.
Snow accumulation can overload trackers, increasing the risk of damage and reducing power output. Snow protection mode adjusts tracker angles to prevent buildup.
