Solar PV Installation in Rendlesham, Woodbridge (3.92kW)

In May 2011, PV Fit installed a 3.92kWp solar PV system for Steve Whiting in Rendlesham, Woodbridge.

Mr Whiting was recommend PV FIT Ltd by his brother-in-law whom had a solar pv system installed by us in July 2010. Despite the recommendation he still obtained 3 quotes and when comparing like for like we came out top.

We specified a 16 panel PV array is located on the front SE facing roof. The solar panels are positioned in 2 rows of 8 portrait.

Mr Whiting is now benefiting from the Governments tax free Feed-in Tariff (FIT) scheme which is offering them an estimated annual return of over 12% per year on his investment!
