Abstrakt
Päikeseenergia on piiramatuim loodusressurss. Päikeseenergiat saab elektriks muundada
protsessiga, milleks vajalikud seadmed on hääletud ning suhteliselt töökindlad liikuvate osade
puudumise tõttu. Samuti ei kaasne elektritootmisprotsessi kestel keskkonnareostust. Uuringu
eesmärgiks on päikeseenergiast elamu tarbeks autonoomse elektritootmise optimeerimine.
Selle tarvis uuriti põhjalikumalt kahte Elektrilevi OÜ kolmest offgrid-projektist. Üksikasjalik
teave esitatakse jaama töös tekkinud probleemide kohta, otsides põhjusi ja leidmaks lahendusi
nende kõrvaldamiseks. Töös käsitletakse üksikasjalikumalt plii-happeakude kontseptsiooni.
Järgnev analüüs viiakse läbi jaama jälgimisseadmest saadud teabe abil. Eesti laiuskraadidel on
problemaatilisemad just talvekuud piiratud päevavalguse esinemise aja tõttu, mis tingib
vajaduse täiendavate, alternatiivsete energiaallikate, näiteks varugeneraatori järele. Jaamas on
esinenud probleeme, mil varuregulaator ei seisku ilma manuaalse sekkumiseta.
Solar energy is the most unlimited resource. Electrical energy can be produced from solar energy in a process where the necessary devices are inaudible and quite invulnerable as there are no moving parts. Also, there is no pollution created by the electricity production process. The main objective of this research is the management of the grid-independent electricity production for a residential house from solar energy. For this, two offgrid projects from Elektrilevi, LLC was explored, as an example. Detailed information is presented about the problems encountered during the operation in the station, looking for causes and finding solutions for their elimination. The concept of lead-acid batteries is discussed in more detail. The subsequent analysis is conducted using the information derived from a station’s tracking device. The winter months are more problematic, as the Estonian latitude has a very limited time of daylight and therefore additional energy sources like a spare generator were needed. There have been problems at the station when the spare generator does not stop without manual intervention.
