Lõputöö teema valiti seoses päikeseenergia populaarsemaks muutumisega. Töö käsitleb
paneelide koguvõimsuse suurendamise tehnilisi võimalusi stringi kohta inverteri suhtes.
Lõputöös simuleeritakse selleks erinevaid lahendusi.
Töö on koostatud teoreetilisel baasil, kasutades selleks erinevate tootjate programme ning
simuleerides läbi lahendusi. Üritatakse leida, kui palju on teoreetiliselt võimalik suurendada
paneelide koguvõimsust inverteri suhtes ning püütakse välja tuua ka asjaolud, mis hakkavad
edasist üledimensioneerimist piirama.
Lõputöös jõuti tulemuseni, et üledimensioneerimine on teatud piirini mõistlik ning arvestades
tootjate ettekirjutusi saaks suurendada kogu süsteemi tootlikkust. Samuti leiti mõned
dimensioneerimist piirama hakkavad asjaolud- näiteks stringide nimipinge ning tootjapoolne
garantii.
The subject of this thesis was chosen because of the solar energy is getting more popular. The thesis will address technical possibilites of PV panels oversizing compared to inverter rating power. The thesis will contain simulation data of oversizing possibilities. The thesis is based on a theoretical basis using different manufacturers programmes and simulations based on them. The author will try to find how much is possible to oversize the panels compared to inverter and find out restrictions for doing it. In conclusion, there was found that oversizing is reasonable until some point, if to take into account the manufacturer’s recommendations and guidelines the system’s capacity can be increased. There were some things also found that will start to restrict the overdimensioning, such as the voltage of strings and the manufacturer’s warranty for the inverter.
