Magistritöö annab ülevaate päikesepaneelide tüüpidest, nende tööpõhimõttest ja tootlikust
mõjutavatest teguritest. Veel antakse ülevaade veeboileritest ja küttekehadest. Töö
eesmärk on leida optimaalsed eelsoojendusboileri suuruse ja päikesepaneelide võimsuse
suhted süsteemi puhul, kus kasutatakse päikesepaneele elekterveesoojendi ühendusega
eelsoojendusboileri kütmiseks. Leitakse ka taastuvenergia osakaal ja tasuvusaeg. Töö
eesmärgi saavutamiseks loodi mudel SciLab 6.1.1 keskkonnas kasutades ka Coselica
plokke. Andmete töötlemise jaoks loodi Pyhton skript. Antud töös kasutatud
sisendandmete, mudeli ning süsteemi puhul selgub, et simuleeritud lahendustest kõige
optimaalsem eelsoojendusboileri ja paneelide võimsuse suhe on 80 liitrine
eelsoojendusboiler ning 1 kW päikesepark. Selle lahenduse tasuvusaeg on 4,28 aastat ning
taastuvenergia osakaaluks on 50,01 %.
The master's thesis provides an overview of the types of PV solar panels, their working principle and the factors affecting productivity. An overview of water boilers and heaters is also given. The aim of the work is to find the optimal ratios of the size of the preheating boiler and the power of the solar panels in the case of a system where solar panels are used to heat the preheating boiler connected to an electric water heater. The proportion of renewable energy and the payback period are also found. To achieve the goal of the work, the model was created in the SciLab 6.1.1 environment using Coselica blocks. A Python script was created for data processing. With regard to the input data, model and system used in this work, it turns out that the most optimal ratio of preheating boiler and panel power from the simulated solutions is a 80 liter preheating boiler and a 1 kW solar park. The payback period of this solution is 4,28 years, and the share of renewable energy is 50,01 %.
