We had a 9 panel system installed in July 2011. The average generation has been 1840 units per annum. FIT payments and not having to buy these 9200 units has been worth approx £6300 so we expect the capital cost will be recouped within the projected 12 years. The"deal" was index linked, guaranteed for 25 years. We had to consider our age at the time and any investment returns from the capital but these have been low during the last 5 years. We will have to renew the inverter at some time (typical life span is 10 years). Overall, it appears to have been a sound investment and pv is still worth considering although the FIT and installation costs have changed considerably since 2011.
