Concerns Extreme Price Variation: The massive range in prices raises serious doubts about the veracity of the turbine prices at the extreme low-end of the scale. If these are indeed the correct prices, and they are of reasonable quality, it begs the question of how all the other companies can possibly compete in the market. Turbine Quality: It should be noted that some of the internet retailer sites with the cheapest turbines raised serious doubts about the quality of the product. For example, they explicitly stated that there were no product guarantees and all sales were final. In addition, very few independent product reviews were available, and those that were found were not very positive. Hidden Costs: With many of the cheaper models it is doubtful that necessary items are included. If for example we take a look at the D400 Wind Generator 7 , which is one of the few small turbines that details the price of various components, the price for the 0.4 kW turbine alone is 49,400 MUR, the control unit for grid connection is 25,200 MUR, the mounting bracket is 12,300 MUR, and the grid tie inverter option is 30,700 MUR. Thus on a per Watt basis the turbine costs anywhere from 188 to 295 MUR, depending on what options are included. On to this there are then the added costs of delivery and installation. Quantity of Sources: While there is a reasonable sample size in terms of the amount of turbines, there are only 7 different retailers utilised. More retailers would raise the statistical strength of the above figures. Conclusions After a desktop search it is apparent that there is an extremely large range in the prices and likely quality of the mini turbines. The very cheapest turbine prices are from sources that are questionable at best. There is a definite tendency in that data indicating that the per kW price decreases with the size of the turbine. Prices per W range from 50 – 350 MUR, depending on what inputs are included. When looking at turbines that included many of the normally required components (inverter + tower), prices for the smaller turbines ranged from 85 –350 MUR/W. In the few instances where it is certain that prices for all components required for grid connection were included, the price was roughly 300 MUR/W. All the above prices above are without delivery and installation costs. In arriving at the figures displayed in table 6, delivery and installation costs were added to acquisition costs of roughly 300 MUR/W for the micro turbine, 200 MUR/W for the mini turbines, and 100 MUR/W for the small turbine. 7 http://www.energyenv.co.uk/D400WindTurbine.asp 19
