ECONOMIC ANALYSIS

The table below shows the results for the capital recovery time of the system in the three different areas:

These results show that the system is not economically feasible when grid connection option is available. But, as it was said in the introduction there are an estimated million houses isolated from the grid in the European Union and as is pointed out in the Rappenecker Hof study developed by Schmid et al, 1998 and Fraunhofer Institute, 1998 and 1991, the cost of grid connection for this isolated houses could often exceed  £ 77,000. In such cases the system is more economically attractive as it can be seen in the table below:
