Abstrakt
Bakalaureusetöö uuritavaks objektiks on Pärnumaal, Tori vallas, Muraka külas paiknev
suvila, kus puudub elektrivõrgu ühendus. Peale suvila suuremaks ehitamist soovitakse
hoones kasutada päikeseenergial põhinevat elektritootmist. Töö eesmärk on välja selgitada
oletuslik tarbimine ning valida selle põhjal sobilikud päikeseenergia süsteemi seadmed.
Kinnistul asub suvila ja abihoone, seadmed hakkavad paiknema abihoones ning
päikesepaneelid paigaldatakse maaraamidega kõrval olevale heinamaale. Ööpäevane
energiatarve oli 1667 Wh, kus arvestati seadmete võimsust ning tööaega ööpäevas. Sellest
lähtuvalt arvutati sobilik akupanga mahutavus, milleks saadi 347 Ah. Valitud akudega
saavutati akupank mahutavusega 450 Ah ning süsteemi pinge määrati 24 V DC.
Vajaminevate päikesepaneelide arvutuslik võimsus tuli 1256 W. Inverteriks ning
laadmiskontrolleriks valiti kaks ühes seade Victron Energy EasySolar 24/1600/40. Valikul
sai määravaks kompaktsus ning valmis terviklahendus. Kogu süsteemi arvutuslik
maksumus tuli 4748,7 €. Kuna eelnevalt puudus hoonel energiatarbimise ajalugu ning
seadmed on valitud arvutuslikul meetodil, siis järgmine samm oleks valmis süsteemi
paigaldamine ja katsetamine. Selle tulemusena saaks teha täiendusi antud süsteemis.
The subject of the bachelor thesis is a summer house in Pärnu County, Tori municipality, Muraka village, where currently there is no grid connection. After the summer house expansion, the building would be using off-grid PV-system. The purpose of the thesis is to identify the hypothetical consumption and based on this info choose suitable PV-system equipment. The property has a summer house and ancillary building. The equipment will be located in the ancillary building and the solar panels will be installed in the field next to the building with ground frames. The calculated daily energy consumption was 1667 Wh, which was calculated taking into account the equipment power and equipment working hours per day. According to the calculations, the capacity of a suitable battery bank was 347 Ah. The battery bank reached 450 Ah with the selected batteries and the system voltage was set to 24 V DC. The calculated solar panel power was 1256 W. Two in one device Victron Energy EasySolar 24/1600/40 was chosen as an inverter and a solar charge controller. The compactness as well as the complete solution became the determining factor in the choice of devices. The calculated cost of the whole system was 4748,7 €. Since there was no history of energy consumption in the building and the system was computationally selected, the next step would be to set up and test the finished system. After the testing has been done, the system could be upgraded.
