Abstract

Cilj rada je optimiziranje proizvodnje električne energije financijski i električki s obzirom na zahtijevanu očekivanu potrošnju našeg zadanog sustava. U prvom dijelu rad je teorijski obrađen, gdje se obrađuju, općenito, fotonaponski sustavi. Zatim, u našem zadatku nalazi se potrošnja koja je konstantna i predvidiva, te na temelju toga moramo prilagoditi već postojeći fotonaponski sustav proizvodnje električne energije. Postojeći fotonaponski sustav postao je nedostatan u proizvodnji električne energije za proces hlađenja mošta pomoću kojeg u kontroliranim uvjetima proizvodimo kvalitetnije vino. U našem radu za rješavanje ovog zadatka koristili smo programski paket PV*SOL premium. Pomoću programa došli do električki zadovoljavajućih rezultata tako što smo u jednom slučaju povećali broj solarnih panela i promijenili inverter, u drugom slučaju smo povećali broj baterija, a u trećem slučaju povećali smo broj baterija, solarnih panela i stavili novi inverter. Nakon financijske analize, koja je uslijedila, došli smo do zaključka da je najbolje rješenje povećati broj solarnih panela na postojećem krovištu objekta i uložiti u novi inverter.

Abstract (english)

The aim of this work is to optimize the production of electricity financially and electrically with regard to the required expected consumption of our given system. In the first part, the work is theoretically processed, where, in general, photovoltaic systems are processed. Then, in our task there is consumption that is constant and predictable, and based on that we have to adapt the already existing photovoltaic system of electricity production. The existing photovoltaic system has becom insufficient in the production of electricity for the process od cooling the must by which we produce better quality wine in controlled conditions. In our work, we used the PV*SOL premium software package to solve this task. With the help of the program we came to electrically satisfactory results by increasing the number of solar panels and changing the inverter in one case, increasing the number of batteries in another case, and increasing the number of batteries, solar panels and installing a new inverter. After the financial analysis that followed, we came to the conclusion that the best solution is to increase the number of solar panels on the existing rood of the building and invest in a new inverter.
