Abstract
U ovom radu realiziran je sustav za ispitivanje fotonaponskog modula, odnosno mjerenje određenih parametara fotonaponskog modula temeljen na Arduino sustavu. Parametri fotonaponskog modula koji se promatraju su napon, struja, snaga i energija. Pomoću strujnog osjetila INA219 mjeri se struja dok se napon fotonaponskog modula mjeri preko naponskog djelila, te umnoškom ovih dvaju vrijednosti dobiva se snaga, te se onda snaga pomnoži s vremenom da se dobije energija koju proizvede fotonaponski panel. Za prikaz dobivene vrijednosti koristi se LCD prikaz. Količina dobivene energije ipak ovisi o veličini sustava izloženoj sunčevoj svjetlosti pa je na sustav spojena i baterija kako bi se pohranio višak energije, te omogućilo lakše funkcioniranje u uvjetima sa smanjenim sunčevim zračenjem. Solarni paneli imaju maksimalnu snagu, odnosno generiraju maksimalnu energiju kada sunčeve zrake padaju okomito na panel pa je zato implementiran i dvoosni sustav za praćenje sunca. Za određivanje položaja sunca korištena su četiri fotootpornika. Upravljački krug obavlja zadatak unosa signala s osjetila te daje naredbe za pokretanje motora kako bi se pratila promjena položaja sunca.
Abstract (english)
In this thesis a system is implemented for testing photovoltaic modules, i.e. measuring certain parameters of photovoltaic modules based on the Arduino system. Parameters of photovoltaic module which are monitored are voltage, current, power and energy. Current is measured by the current sensor INA219 while voltage of photovoltaic module is measured with the voltage divider, so by multiplying these two values power is obtained, and then power is multiplied by time to obtain the energy generated by the photovoltaic panel. An LCD display is used to display the measured values. However the amount of gained energy depends on the size of the system and the exposure of the sunlight, so the battery is also connected to store the excess energy and make it easier to operate in conditions with reduced solar radiation. Solar panels have maximum power, i.e. generate maximum energy when the sun rays strike perpendicular to the panel, that’s why a dual-axis sun tracker system is implemented. Four photoresistors are used to sense the change in the position of the sun. The control circuit performs the task of getting signal from the sensors and gives commands to run the servos to track the sun.
