Sensing solutions for photovoltaic solar arrays

Solar trackers maximize the efficiency of photovoltaic solar arrays
Solar trackers maximize the efficiency of photovoltaic solar arrays

Solar trackers maximize the efficiency of photovoltaic solar arrays by continually moving them throughout the day to follow the sun.  Pepperl+Fuchs offers a broad spectrum of sensing solutions tailored to suit the many different solar tracker designs in use today. 

Versatile inductive proximity sensors can be used to provide positioning feedback, end-of-travel limits and confirmation of “nighttime” or “storm safe” positions.  They’re available with extended temperature ranges and IP68/IP69K ratings specifically for outdoor applications. 

Inclination sensors from Pepperl+Fuchs are ideal for monitoring the elevation (“tilt”) angle of horizontal single-axis trackers and dual-axis trackers.  With accuracy of 0.5 degrees and IP68/IP69K ratings, these gravity-referenced devices offer 0-5 volt or 4-20mA analog outputs and programmable setpoint options. 

Rotary encoders can be used for rotational position feedback for any moving axis, thus can be found on trackers of practically any conceivable design, either single or dual-axis.  Absolute rotary encoder models provide reliable, accurate position information, even through power loss.  Pepperl+Fuchs’ new magnetic encoders and inductive position coding systems deliver accurate position feedback using totally sealed, non-contact technology for reliable, long service life in the harshest application environments.
