Abstrakt
Edaspidi nimetuse „fotoelektrilised paneelid“ asemel kasutatakse rahvusvaheliselt tuntud
lühendit PV-paneelid.
Projekteeritud päikese PV-paneelide positsioneerimise juhtseadmega on võimalik juhtida PVpaneelid
vastavalt kiirguse tugevusele just sellise asimuudi- kui ka elevatsiooni nurga alla, kus
PV-paneelide võimsus oleks maksimaalne päikese tõusust päikese loojanguni.
Positsioneerimisseadme projekteerimisel on leitud lahendus, mis võimaldab üks kuni n sellist
seadet süsteemi lisada nii, et ei tekiks probleeme nende koos töötamise käigus. Projektile on
lisatud nõuded programm varustusele, mis võimaldaksid positsioneerimise seadmel toimida,
nii nagu on projektis ettenähtud. Projekti tulemusena arendatakse välja süsteem, mis
võimaldab PV-paneelide plokke süsteemi juurde lisada nii palju, kui on tarvis nt väikeelamu
autonoomsemaks muutmiseks.
The designed solar PV panel positioning control device enables to change the azimuth and elevation angle of PV panels in a way that allows he panels to work at maximum capacity from sunset to sundown, taking into account the solar radiation strength. That would ensure the maximum efficiency of PV panels. The positioning controller changes the position of panels, using the azimuth and elevation motors, according to information provided by the radiation sensor pyramid. When designing the positioning device, a solution was found that allows to add 1…n devices into the system in a way that will not cause problems when all the devices are working simultaneously. The cost of the devices was not taken into account in the designing process since it is simply a provisional system solution and is not meant to be built yet. Electrical systems were created and pcb layouts designed using the Eagle 6.5.0 software. A large part of the work was selecting the electronics components that would ensure the functionality and reliability of the system. The project includes program requirements that would enable the positioning device to function in the way the project intends. A computer program allows the positioning devices added into the system to work and also to monitor the sensor data via Internet from anywhere around the world. Data provided by the sensors can be saved in the computer and an SD card reader has been integrated into the system as backup. Data can be retrieved from the card in case of computer malfunction. As a result of the project, a system is developed that enables to add as many PV panel blocks into the system as needed, for instance when making a small residential building more autonomous.
