Wago solar positioning function block
By Alyssa Dalton
Wago claims its Solar Positioning Function Block (SPFB) increases concentrated solar arrangement efficacy, as it enables dynamic solar mirrors to track the sun’s arc within +0.02o via the Wago-I/O-System. For East-to-West tracking, SPFB relies on multiple variables and inputs, including atmospheric pressure, site elevation, azimuth, latitude, longitude, date and local time. Calculations are then paired with the internal clock of a Wago programmable fieldbus controller, “optimizing mirror position”. Data is communicated to a connected Wago DC motor control module and encoder, or other component (e.g., variable frequency drive) for alignment.
