Abstract: Chalmers University of Technology owns a hybrid power facility located on the island Hönö, in the archipelago of Gothenburg, Sweden. The aim of this project is to analyze and evaluate if the hybrid power facility is able to produce more energy than it consumes on an annual basis. The hybrid power facility was put in use two years ago when the solar panels, Naps Pallas, and the wind turbine, Windstar 3000, were purchased and installed. The solar panels consists of 15 solar cells and Windstar 3000 is a five-bladed wind turbine with a rated power of 3 kW. The solar panels have been generating electricity as expected, but Windstar 3000 was forced to be taken down a few days after installation due to not being properly mounted. Besides not being properly installed it lacked a functional breaking mechanism that protects the turbine from breaking at higher wind speeds. Nor did the inverter to the wind turbine have an optimal power curve, adapted to give optimal energy production. This caused the wind turbine to produce lower power than it was supposed to. To assure that the facility has a higher energy production than consumption, a system had to be designed and installed that collects the energy data from the facility. Due to lack of time only a part of the breaking circuit was made, the frequency measuring circuit. Arduino Nano was used for this purpose. The wind turbine had stopped working when this circuit, in combination with a part of another breaking circuit, was installed. Even though the wind turbine was taken down and analyzed, no errors were found and neither the breaking system or the final power curve could be tested. With help from older weather statistics and the data collection system, made with both Raspberry Pi 2 model B and Arduino Mega 2560, a conclusion could be made regarding the energy production of the non-functional Windstar 3000. This conclusion would prove that it would be possible for the wind turbine and the solar cells to produce enough energy to overcome the consumption of the hybrid power facility.
