Diplomsko delo vsebuje opise in prikaze postopkov za izgradnjo krmilnika za fotovoltaični sledilnik in rezultate. Sledenje soncu smo izvajali po dveh prostostnih stopnjah, s čimer lahko dosežemo celodnevno optimalno orientacijo sončnega panela. Krmilnik je bil zgrajen z ARM mikrokrmilnikom LM3S8962. Implementirani algoritmi omogočajo sledenje soncu s svetlobnimi senzorji ali s solarnim algoritmom, ki določa gibanje sonca za vsako točko na zemeljski obli z vpisom zemljepisne širine in dolžine. Krmilniku smo dodali še PŠM gonilnik DRV8412 z dvema H-mostičema za električni pogon sledilnika. Krmilnik smo preizkusili, tako naloga vsebuje tudi eksperimentalne meritve. Diploma thesis consists of descriptions and demonstrations of procedures for the construction of controller for photovoltaic solar tracker and the results. We have followed the sun by two degrees freedom levels with which we can reach an all-day optimal orientation of the solar panel. Controller was built with ARM microcontroller LM3S8962. Implemented algorithms enable following the sun with the light sensors or with solar algorithm that provide the sun movement for every point on the globe by entering latitude and longitude. To controller we have also added PWM driver DRV8412 with two H-bridge for the electrical power of the tracker. We have tested the contoller so the thesis also consists of experimental measurements.
