Solar PV Installation in Barton-Upon-Humber near Hull (3.92kW)

In February 2011, PV Fit installed a 3.92kWp solar PV system for Mr & Mrs Grimbleby in Barton-upon-Humber, near Hull.

Mr & Mrs Grimbleby, Barton-upon-Humber

The PV array is located on 3 separate roofs, comprising 6 panels on their SSE facing roofs and 11 panels on 2 WSW facing roofs. Mr & Mrs Grimbleby chose PV Fit due to our competitively price and the ability to monitor how much energy they are generating in real time through the free solar inverter web monitoring service. Web monitoring provided extra peace of mind as we at PV FIT can monitor system performance and identify any issues without having to visit the property.

They are now benefiting from the Governments tax free Feed-in Tariff (FIT) scheme which is offering them an estimated annual return of over 13% per year on their investment.
