This work is evaluating a PV-Wind Hybrid system that has been installed in 2006 on the roof of Dalarna University in Borlänge/Sweden. Complementing the measurements, simulations with HOMER have been performed for the same system type. The measurements results showed that the PV array of the PV-Hybrid system was providing the major part of the energy even it has only the half of the wind turbine’s nominal rated power. However, the energy production of wind turbine especially during December and January allowed providing an almost constant load of 35W throughout the year. The combination of PV and wind increases the reliability of power supply and allows a significant smaller PV array compared to a PV alone system. The simulation results with HOMER showed good accordance with the measured data. The maximal difference was 3%. Furthermore, HOMER proved to be an easy to use and powerful tool for the sizing of this system type for locations where weather data for solar radiations and wind speed are available.
