Abstract
Predstavljen je razvoj sistema za ogrevanje sanitarne vode s sončnimi moduli. Predstavljeni so uveljavljeni sistemi za solarno ogrevanje sanitarne vode. Električni sončni moduli se večinoma uporabljajo za sončne elektrarne. Zaradi vedno nižje cene električnih sončnih modulov in nekaterih prednosti, ki jih imajo moduli pred kolektorji, pa postajajo zanimivi tudi za ogrevanje vode. V delu bo obravnavana razlika med obema sistemoma s podanimi prednostmi in slabostmi enega in drugega. Obravnavana bo tudi smiselnost uporabe električnih sončnih modulov tam, kjer že obstaja električno omrežje. Za višji izkoristek električnih sončnih modulov je bil razvit regulator, ki s posebnim algoritmom vzdržuje razmerje med napetostjo in tokom na panelih tako, da proizvajajo maksimalno moč. Hkrati je regulator prilagojen gretju vode v klasičnem rezervoarju vode za hišne potrebe, kar zniža stroške razvoja in izdelave. Za popolnoma samostojno delovanje sistema je bil dodan programirljiv logični krmilnik.

Title:Maximum power point tracking algorithm development for solar cells and comparison of solar energy receivers
Abstract:
The thesis describes development and implementation of domestic water heating system using photovoltaic modules. The standard widely used flat plate solar collectors are presented alongside so that the new system can be compared and evaluated. One reason for developing this new system otherwise mostly used for solar power plants is the recent price drop of photovoltaic modules. The other reasons are many advantages that photovoltaic modules offer over solar collectors. This thesis will compare old and well known system with solar collectors and newly developed system with photovoltaic modules. For achieving a higher efficiency of solar cells an improvement on existing algorithm was made. A special controller for the system was designed to replace expensive inverters so that the cost of the complete system can be reduced to minimum. The thesis covers this aspect and accesses whether the photovoltaic industry is a net electricity producer or a consumer.

Keywords:energy, water heating, solar power, solar collectors, photovoltaic modules, MPP-algorithms
