This thesis considers the integration between Savonius wind turbines and photovoltaics to form a hybrid power system. Different integration techniques were studied to find the most suited technique and the necessary components. The hybrid system was then to be compared with a solar panel system of equal sizing to investigate whether it could compete in terms of production and profitability. A model of the hybrid systems was built in MATLAB Simulink to simulate the production of the systems. Simulations used SMHI measurement data over wind speeds, solar radiation and temperature, with data resolution of one hour for 2017. The Swedish electricity trading market was also studied to determine which guidelines and prices that apply when selling electricity to the grid. The investment costs for the systems were estimated to allow economic conclusions to be drawn. The result was that a hybrid system had a higher power delivery to the load but the total production was higher for the solar system. The hybrid system couldn’t compete with the profitability of the solar system in the studied case. Possible reasons for the result was that the wind resources at the tested location wasn’t enough and that the price for wind turbines was high. Conclusions was that the price of the turbines needs to decrease in order to make the hybrid system more competitive. For hybrid systems that contain wind turbines, it is important that the chosen site has good wind resources to take advantage of the potential of the turbines.
