Keskkonna jätkusuutlikuse huvides on arenev osa elektrienergia tootmisel
taastuvenergiaallikatest. Päikeseelektrijaamadega elektrienergia tootmine on nii Eestis
kui mujal maailmas pidevas arengus. Päikesekiirguse intensiivsus on suhteliselt
varieeruv suuremate vahemaade vahel. Töö eesmärgiks oli välja uurida mobiilse
mõõteseadme päikese kiirgusandmete hõiveks vajalikkus ning koostada seadme
kontseptsioon. Eesmärgi saavutamiseks uuriti päikesekiirgust üldiselt, päikesekiirguse
intensiivsust Eesti eri punktides ning koostati seadme kolmemõõtmeline kontseptsioon
koos seadmete valikuga. Päikesekiirguse andmed pärinevad Keskkonnaagentuuri poolt
esitatud andmemassiividest, mis on mõõdetud kaheksas Eesti meteojaamas. Samuti
käsitleti päikeseelektrijaamade potentsiaalseid asukohti ja tootlikusi vabavaralise
tarkvaraga PVGIS. Koostati seadme kontseptsioon ning valiti vajaminevad
komponendid seadme töökorda seadmiseks. Päikesekiirguse anduriga teostati katselised
mõõtmised Eesti Maaülikooli Tehnikainstituudi katusel ning mõõteandmeid võrreldi
samas asukohas oleva ilmajaamaga. Võttes arvesse andmehõivesüsteemi tarbijate
tarbimist, arvutati seadme salvestusseadme vajalik mahtuvus.
Environmental sustainability creates a growing interest in electricity production from renewable energy sources. Using solar power for energy production in Estonia and elsewhere in the world is in constant evolution. Intensity of solar irradiation may vary significally between larger distances on Earth. The aim of this masters thesis was to find out the necessity for mobile device for solar irraditon data acquisition and to create a concept for the device. In order to achieve the given aim, solar irradiation in general, the intensity of solar irradiation at several different places in Estonia and given device´s possible concept with the choice of equipment was studied. Solar irradiation data was acquired from Estonian Environmental Agency which are measured in eight different meteorological stations in Estonia. In this thesis, it is also discussed the potential locations of solar power plants in Estonia using free software PVGIS. A concept of the device was modelled and required components are chosen. Experimental measurements were carried out with the irradiation sensor on the roof of Estonian University of Life Sciences Technical Institute building. Measured irradiation data was compared to an existing weather station´s measured data. Taking into account the data acquisition device´s electrical consumers total consumption, the required capacity of the storage device was calculated.
