Challenge
Conventional brush-type slip ring in the pitch-control hub required quarterly maintenance and failed prematurely in high-humidity coastal sites.
Solution
LTN SC050 maintenance-free slip ring with gold-on-gold contacts and hermetic sealing fitted to hub; Murrplastik UV-rated conduit used for lead-ins.
Maintenance interval extended from 3 months to over 3 years; slip ring failures at coastal site reduced to zero over a 2-year period.
Challenge
Single-axis encoder feedback missed cross-axis tilt caused by ground settlement, reducing tracker efficiency by 4% on a 5 MW field.
Solution
Siko IK360 dual-axis inclinometer with CANopen output added to tracker frame; signal fed to Unitronics Unistream PLC for real-time correction.
Tracker efficiency recovered to within 0.3% of design; payback on sensor upgrade achieved in under 6 months of energy savings.
