The average revenues per family is 813.56 US$ for the case <strong>of</strong> 5 years project span and 5% discount rate, 861.59 US$ for the case <strong>of</strong> 5 years and 3% discount rate, 1451.98 US$ for the case <strong>of</strong> 10 years project span and 5% discount rate and finally 1604.52 US$ for the case <strong>of</strong> 10 years and 3% discount rate. NPV - Revenues (5 years – 5% rate) NPV - Revenues (5 years - 3% rate) NPV - Revenues (10 years - 3% rate) 576 610 1136 1028 NPV – Revenues (10 years – 5% rate) It is clear that the differences in the NPVs for the same life span but different discount rates are trivial. The highest revenue will be achieved with the life span <strong>of</strong> 10 years and discount rate <strong>of</strong> 3%.
