COMPARISON OF SMALL SCALE WIND TURBINES' PROPERTIES

Manufacturers from all over the world produce many types of small scale wind turbines, which parameters are measured under different conditions. Therefore comparison and choosing of the small wind turbine are not very simple tasks. The method used for comparison of small wind turbines by means of comparative indexes is presented in this paper and applied for the evaluation of 45 small wind turbines of horizontal axes and 14 small wind turbines of vertical axes. Calculations of the comparative indexes of the selected small scale wind turbines were carried out on basis of data from internet. The rating of small wind turbines from both classes according to the comparative indexes was carried out and the corresponding results presented in the paper. A distinct general superiority of small horizontal axis wind turbines against the vertical axis wind turbines is showed by means of columnar diagrams.
