Solar Panel Case Study - PV installation process


This is a typical PV system being installed on a detached house in Hove.

8 x 185W Sharp mono crystalline PV modules combine to give a 1.48 kWp ystem. The DC electricity is fed to a SMA SB1200 inverter, in this case located in the garage next to the distribution board.

The Total Generation Meter is located inside the property for ease of access for the FIT readings.

Annual yield expected 1,250 kWh Total energy yield over 25 years expected 30,500 kWh Total CO2 offset over 25 years expected 16,500 kg Total FIT earnings over 25 years expected £13,678

Feed in Tariff scheme

The FIT is a scheme in which owners of PV systems are rewarded for every unit of electricity they generate, irrespective of whether they are used on site or not.

This is known as the Generation Tariff and is currently under review. Payments are also made for 50% of every unit generated by the PV system. This is known as the Export Tariff and is currently under review. These payment rates are fixed for 20 years, linked to the Retail Price Index (RPI) and are tax-free. PV systems installed from 1 August 2012 will be subject to an approximate 7% decrease in the FIT rates.
