DEMO DAY innowacji 4.0

There is a huge variety of wind turbines on the market. For the most part, these structures are very large and unsuitable for the wind conditions prevailing in the Polish area. Available designs of small household wind turbines also fail to realize their potential and are not optimized for domestic use. In the reported solution, the essence is the prototype of a unique small compact VHAWT backyard wind turbine optimized for the low wind speeds most common in our country, which will be used for efficient conversion of wind energy into electricity. The developed solution is based on three unique features not found in other solutions: (a) it uses a vertical-axis turbine installed horizontally, (b) the location of the wind turbine is carefully selected, it is placed on the building in such a way that the building mass is treated as a diffuser that increases the wind speed locally, (c) the rotor of the wind turbine is specially designed for the "diffuser" and wind speeds most common in our Country. The solution will be adapted to the use of wind characterized by low values of air speed and high and rapid variation of speed. The designed device will be able to be used by individual users and will be characterized by low noise and aesthetics. The proposed solution will allow local electricity production and is an excellent complement to the currently commonly installed backyard photovoltaic systems. The estimated value of electricity production from the proposed wind turbine is three times greater than that from photovoltaic systems (of the same capacity), and is highest in the autumn and winter when sunshine is lowest, which is extremely beneficial to both the local user and the national electricity system.
