Abstract [en]

The purpose of this project is to investigate if it is possible to get more energy out of a solar panel if the solar panel is always directed towards the sun. Furthermore, two questions surrounding the plausibility of building an efficient tracking system, and the level of complexity for the required software and mechanism will be investigated. To be able to answer these questions a prototype was built.

This project consists of three major parts, hardware, software and electronics. Stepper motors were used to rotate the solar panels and light dependent resistors (LDR) were used as light sensors.

With the tracking system, the solar panels outputted 48 % more energy.

Abstract [sv]

Syftet med detta projekt är att undersöka om det är möjligt att erhålla mer energi från en solpanel om solpanelen alltid är riktad mot solen. Vidare ska två frågor angående om det är möjligt att konstruera ett system som effektivt följer solen med ljussensorer och hur komplicerad den tillhörande mjukvaran blir besvaras. För att finna svar på dessa frågor har en prototyp skapats.

Detta projekt består av tre avgörande delar, hårdvara, mjukvara och elektronik. Stegmotorer används för att rotera solpanelerna och light dependent resistor (LDR)-motstånd används som ljussensorer.

Med det solspårande systemet erhölls 48 % mer energi från solpanelerna.
