Antud lõputöös tutvustab autor erinevaid tehnoloogiaid, mille abil muundatakse
päikeseenergia elektrienergiaks. Tuuakse välja nendega seotud eelised ja puudused ning
antakse ülevaade turu olukorrast. Töö eesmärk on uurida päikespaneelide probleeme ning
nende eelistatud paigaldusviise tuginedes modelleeritud süsteemile. Antud tulemuste
saavutamiseks on koostatud elamust 3D mudel, hangitud elamu tarbimisandmed, koostatud
simulatsioone erinevate PV süsteemidega ning tulemusi omavahel töödeldud. PV
süsteemide tasuvusaeg on seda kiirem, mida rohkem suudetakse koha peal toodetud
elektrienergiat ära tarbida. Modelleeritud süsteemide puhul suudetakse enim oma tarbeks
ära kasutada kaldkatusele paigutatud lahenduste korral, moodustades keskmiselt 34,09%
aastasest energiatarbest. Sellest tulenevalt oleks vaadeltavatest variantidest kõige
optimaalsemaks lahenduseks just kaldkatusele paigaldatud süsteemid. Arvestades seda, et
hoone elektritarbimine perioodil, mil päikesepaneelide tootlikkus on tipus, moodustab
keskmiselt 20% kogu päevasest tarbimisest, siis poleks otstarbekas investeerida
suurematesse süsteemidesse.
In this thesis, the author introduces different technologies, which are used for converting solar energy into electricty. Author explains the disadvantages and advantages of this technology and gives an overview of the market situation. The aim of this thesis is to investigate the problems behind solar panels and to compare their preferred installation methods by relying on the simulated situations. In order to achieve these goals, a 3D model of a building was made, the consumption data of the building was gathered, situations with different PV systems were simulated and then the data got examined. The payback period of the PV systems is shorter the more you are able to consume the produced electricity on site. In the simulated situations, the best numbers were shown in terms of own consumption, in systems which were placed on top of the building’s 45⁰ roof. Due to all that, the most optimal solution from all the simulated systems, would be the ones on the inclined roof. Cosindering the fact, that the building’s electricty consumption at the period, when the PV systems production is at it’s peak, accounts for 20% of the daily consumption, then it would not be rational to invest into bigger systems.
