January 5, 2011 – WAGO releases free Solar Positioning Function Block (SPFB), which increases concentrated solar arrangement efficacy. SPFB achieves this by enabling dynamic solar mirrors to track the sun’s arc within +0.02° via WAGO-I/O-SYSTEM. Sunnyside Up:For precise East-to-West tracking, SPFB relies on multiple variables and inputs. These include 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. Unlike many traditional sensor-driven systems, WAGO SPFB provides remote access and manual control by linking to a central PC via fieldbus. System status/alarms are available via e-mail, and a “stow” feature positions panels horizontally (wind) or vertically (snow), reducing stress during inclement weather. SPFB was developed in-house utilizing data from both the U.S. National Resource Energy Laboratory, and the 2011 Astronomical Almanac produced by the U.S. Naval Observatory and H.M. Nautical Almanac Office.PV Panel Positioning Block: WAGO’s free Solar Tracking Function Block is also available. It allows the WAGO-I/O-SYSTEM to align PV panels with the sun, for 30% more energy production than fixed panels.WAGO is the leader in spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products: DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the WAGO-I/O-SYSTEM and more. Learn More
