Bakalaureusetöö eesmärgiks on uurida elektrilise päikesekütte tehnoloogiaid eramule ja
leida võimalusi, kuidas vähendada võrgust tarbitava elektrienergia hulka tarbevee
soojendamiseks. Uurimustöö aktuaalsus seisneb päikeseenergeetika valdkonna arengus
ning soovil uuritavas objektis võtta kasutusele taastuvenergia lahendused.
Bakalaureusetöö teoreetilises osas vaadeldakse päikeseenergia olemust maailmas,
Euroopas ja Eesti ning antakse ülevaade päikesekütte tehnoloogiatest. Töö praktilises osas
uuritakse objekti ja selle tarbevee ning elektrienergia tarbimist kuude lõikes, leitakse
võimalikud elektriliste päikesepaneeli süsteemide lahendused, arvutatakse tarbevee
soojendamiseks kuluva elektrienergia hulk ning koostatakse energiabilanss.
Päikesepaneelide eeldatava tootlikkuse teada saamiseks objekti asukohas kasutatakse
PVGIS programmi. Päikesepaneelide eeldatava tootlikkuse arvutused objektile tehakse
asimuudiga 90°. Tarbevee soojendamiseks vajalik energia arvutatakse soojushulga
valemiga. Majapidamises tarbitakse keskmiselt 7288,1 kW·h elektrienergiat. Lihtsustatud
arvutustest nähtub, et valitud elektrilise päikesekütte süsteem suudaks tarbevee
soojendamiseks toota elektrienergiat peaaegu üheksal kuul aastast.
The aim of the bachelor's thesis is to study the technologies of electric solar heating for private houses and to find ways to reduce the amount of electricity consumed from the grid for domestic water heating. The topicality of the research lies in the development of the field of solar energy and the desire to introduce renewable energy solutions in the research object. In the theoretical part of the bachelor's thesis the nature of solar energy in the world, Europe and Estonia was examined and an overview of solar heating technologies was given. In the practical part of the work the consumption of the object domestic water and electricity by months was studied, possible solutions of electric solar panel systems for the object were found, the electricity consumed for domestic water heating was calculated and the energy balance was compiled. The PVGIS program was used to find out the expected productivity of the solar panels at the site. Calculations of the expected productivity of solar panels for the object were made with an azimuth of 90°. The energy required to heat domestic water was calculated using the heat quantity formula. The household consumes an average of 7288,1 kW·h of electricity. Simplified calculations show that the chosen electric solar heating system would be able to produce electricity for domestic water heating for almost nine months of the year.
