There are several purposes of this thesis work and it achieves different types of goals. It starts from investigating, sizing, and building ending with measurements and comparison; the typical aims are listed below. • Investigation of the available components of the old wind stand alone system located on the top of Högskolan Dalarna (Borlänge) main building and how these components can be used in a new PV/wind hybrid System. • Size and design a PV/wind hybrid system by a computer simulation program; for Borlänge climate, with a constant load. • Building the designed PV/wind hybrid system on the same location of old wind stand alone system. The construction should be in a way that can be used for future education. • Installing the required measurement equipments. • Measurements on the built system. • Comparison between the measured and simulated results.
