The paper provides an analysis of small wind turbines with less than 10 kW of installed power. Power curves are compared and analyzed for a number of different wind turbines. Furthermore, the possible electricity production is assessed for all of them with their different power curves, same pole heights and wind characteristics using a multiannual array of data measured at a location in Croatia. The impact of the shape of the power curve, together with the turbine rated power relative to its swept area, on the total electricity production and generated income is analyzed and discussed. Results indicate much larger ranges of both potential electricity production and the cost of electricity than expected. (C) 2012 Elsevier Ltd. All rights reserved.
