Solar Positioning Function Block Delivers Accurate Performance

Wago’s free Solar Positioning Function Block (SPFB) increases concentrated solar arrangement efficacy by enabling dynamic solar mirrors to track the sun’s arc within +0.02°. 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 pair with the internal clock of a programmable fieldbus controller to optimize mirror position. Data is then sent to a motor control module and encoder or other component (e.g., variable frequency drive) for alignment. Additionally, the SPFB provides remote access and manual control by linking to a central PC via fieldbus. WAGO CORP., Germantown, WI. (800) 346-7245.
