Solar PV Installation in Nobottle, Northampton (3.675kW)

In April 2011, PV Fit installed a 3.675kWp solar PV system for Mrs Tucker in Nobottle, Northampton.

The 15 panel PV array is located on Mrs Tuckers South facing roof at rear of property . The solar panels are positioned in portrait to maximise the available roof space, including 1 panel located beneath an existing solar hot water system.

Mrs Tucker is now benefiting from the Governments tax free Feed-in Tariff (FIT) scheme which is offering her an estimated annual return of over 13% per year on her investment!

Mrs Tucker says: “I would like to thank you (PV FIT Ltd) for all the help and support you have given me over the past couple of months while I contemplated the roof panels. Not many firms would have replied so quickly to my emails and explained everything as clearly as you did”.
