This chapter aims at giving the reader a wide angle view of available sun tracker solutions and presents some of the solar tracking automation solutions presently available.
Most of these solar tracking controllers are universal controllers suitable for a variety of solar systems and mode switchable to control point focus, linear (parabolic trough) or central receiver Heliostat solar receiver systems. These sun tracker solutions include algorithms for computing the sun vector, mostly for PLC (Programmable Logic Controller) and PAC (Programmable Automation Controller) processors as well as FPGA (Field Programmable Gate Arrays). A number of commercial and proprietary solar tracking controller solutions for a variety of automation platforms are available in the market. doi: 10.13140/.3201 Chapter in free eBook on Solar Tracking Systems, Sun Tracking Systems, Sun Tracker, Solar Tracker, Follow Sun, Sun Position.
