Abstract

The paper analyzes the market of small wind turbines from the economic point of view. The analysis judges an investment in wind energy on the basis of different economic indicators, such as Simple Payback (SPB), Net Profit Value (NPV) and Internal Rate of Return (IRR). Selected turbines from the European and Polish market were picked. The rated power of a wind turbine up to 10 kW was established as the main criterion for the selection. Calculations of the tip-speed ratio and power coefficient and a comparison with the wind resource reference data are presented. On the basis of these considerations, economic effectiveness study is performed via an estimated profit income from the turbine purchase.
