Solar PV Installation in Christchurch, Dorset (2kW)

In March 2011, PV Fit installed a 2kWp solar PV system for Mr & Mrs Williams in Christchurch, Dorset.

The PV array is located on rear South facing roof, and it comprises 10 solar panels. Mr & Mrs Williams were recommended PV Fit by a work colleague who was also obtaining quotes for installation of a solar pv system. They, as well as their work colleague, are now benefitting from the Governments tax free Feed-in Tariff (FIT) scheme which is estimated to offer them an annual return of over 10% per year on their investment.
