Abstrakt
Päikeseenergia on praktiliselt ammendamatu loodusvara. Sellest elektri tootmine on
protsess, milleks vajalikud seadmed on hääletud ning suhteliselt töökindlad, kuna
tootmiseks vajalikel seadmetel puuduvad liikuvad osad. Samuti ei kaasne tootmisega
loodusreostust.
Käesolev bakalaureusetöö käsitleb iseseisvat, peamiselt päikeseenergiast elektrienergia
tootmisprotsessi elamu tarbeks, selleks vajalikke seadmeid ning baasteadmisi.
Energiatootmise protsessi vaadeldakse Elektrilevi OÜ võrguvabade ehk off-grid projektide
näitel. Lähemalt uuritakse ühte, neist mahukaimat projekti, mille seadmepargi ning
töötamispõhimõtete kohta antakse ka detailsem ülevaade.
Eesmärgiks on analüüsida energiatootmise võimalikkusest majapidamisele piisavas
koguses just Eesti valgusevaesetel talvekuudel. Sellekohase analüüsi tegemiseks
kasutatakse antud jaama jälgimisseadmest saadud informatsiooni. Töös esitatud
põhimõtete ja koondatud materjalide toel oleks võimalik päikesest elektrienergia
tootmisest huvitatutel ka iseseisvate lahenduste väljatöötamine. Üheks olulisemaks
tulemuseks antud töös võib pidada kinnitust Eesti laiuskraadidel päikesest elektrienergia
tootmiseks piisava päikesevalguse olemasolu kohta. Probleemsemateks kuudeks on paraku
talvekuud.
Tulevikus oleks võimalik uurimistööd jätkata, kasutades pikema aja jälgimisandmeid ning
analüüsides erinevaid süsteemikonfiguratsioone.
Solar energy is one of the most inexhaustible natural resources. Electrical energy produced from solar energy is a process where the necessary devices are inaudible and quite invulnerable as there are no moving parts. Also, there is no pollution created by electricity producing process. The main objective of this bachelor thesis is handling off the grid independent electricity producing for the dwelling houses basically form solar energy. For this, Elektrilevi, LLC, one of the off-grid projects was explored as an example. Detailed information is presented about one of them, which was the largest of those projects. The device fleet and principles are comprehensively handled. The goal is to analyze the potential for energy production used by homes in sufficient quantities in Estonia during winter months. The subsequent analysis is conducted using the information derived from a stations tracking device. One of the important results of this work can be regarded as confirmation of the sufficient sunlight that is present to produce electricity. However, more problematic are the winter months, as the Estonian latitude has a very limited time of daylight. In the future, it would be possible to continue the research using tracking data of an extended period and analyzing a variety of different system configurations.
