Apstrakt
Precizna procena učinka solarnog fotonaponskog (FN) sistema zavisi od preciznosti softverskih alata koji se koriste za simulaciju. U ovom radu izvršeno je poređenje softvera EnergyPlus i veb-aplikacije PVGIS. EnergyPlus predstavlja inženjerski softver koji omogućava detaljno simuliranje rada FN sistema, uzimajući u obzir veliki broj ulaznih parametara koji utiču na njihov učinak. S druge strane, veb-aplikacija PVGIS nudi pojednostavljen pristup, ali njena tačnost u poređenju sa inženjerskim simulacija nije uvek jasno definisana. Cilj ovog rada je da ispita u kojoj meri PVGIS može da pruži rezultate uporedive sa onima dobijenim pomoću EnergyPlus simulacija. U tu svrhu sprovedene su uporedne simulacije za devet različitih lokacija na teritoriji Republike Srbije. U okviru veb-aplikacije PVGIS realizovane su simulacije primenom dve datoteke meteoroloških podataka (SARAH3 i ERA5), koje su potom upoređene sa rezultatima dobijenim korišćenjem EPW datoteke meteoroloških podataka u softveru EnergyPlus. Rezultati ukazuju na razlike u rasponu od 3,23% do 9,11% između SARAH3 i EPW datoteka, kao i od -2,89% do 1,82% za ERA5 i EPW datoteke. Dodatno, sprovedena je analiza za poznatu lokaciju u centru Kragujevca, na kojoj bi se solarni prijemnik tokom većeg dela godine nalazio u senci. Rezultati EnergyPlus simulacije pokazali su 63,4% manju proizvodnju u odnosu na PVGIS simulaciju sa SARAH3 datotekom, odnosno 65,6% manju u poređenju sa ERA5 datotekom. Dobijeni rezultati jasno ukazuju da PVGIS veb-aplikacija može pružiti dovoljno precizne procene rada solarnih FN sistema kada se koristi ERA5 datoteka, samo ako su analizirane lokacije neosenčene.
