Analysis of the impact of increasing the efficiency of Savonius turbine working in a hybrid system trough the using of building’s elements as curtains

The paper presents Savonius turbine and the results of worldwide research. Statement was made the most optimal geometric parameters and shows how increase a turbine efficiency of energy generation without interfering with the turbine structures, through the use of appropriately selected curtains. Proposed use of building elements to improve the efficiency of the turbine and to create a hybrid system, attaching photovoltaic panels. Calculated energy yield of the entire system and installation diagram is shown in off-grid system.
