Abstract [en]

The purpose of this project was to investigate how efficient it is to implement steering of a solar panel, in one or two axes. To determine how efficient it is, special consideration was taken to the energy usage of the driving system. Practical applications have also been considered with pros and cons. To answer the research questions a prototype was built and a controlled environment for testing was arranged. Rotating the panel in one axis resulted in a 26% energy increase and for the two-axis system a 56% energy increase compared to stationary panel.

The use of stepper motors turned out to be not as efficient as needed, due to continuous use of energy at all times during operation.

Abstract [sv]

Syftet med detta projekt var att undersöka hur effektivt det är att implementera styrning av en solpanel i en eller två axlar. För att kunna avgöra nyttan så togs det hänsyn till drivsystemet och hur mycket energi det gick åt för styrningen. Även praktiska tillämpningar kontrollerades och vilka fördelar och nackdelar som skulle erhållas. För att svara på frågeställningarna, tillverkades en prototyp som testades i en kontrollerad miljö. Genom att rotera panelen runt en axel ökar energiupptaget 26 % och för det tvåaxliga systemet 56 % jämfört med en stationär panel.

Användningen av stegmotorer visade sig inte vara speciellt effektiv då det krävdes kontinuerlig strömmatning för att erhålla det motormoment som krävdes för att hålla panelen på plats.
