Tariff band definitions
Some solar PV tariffs depend on how the system is configured or used. These are the definitions that apply
Where a system type is used to specify a tariff band, the following defeinitions apply:
- “Retrofit” means installed on a building which is already occupied
- “New Build” means where installed on a new building before first occupation
- “Stand-alone” means not attached to a building and not wired to provide electricity to an occupied building
- If no type is specified, the tariffs apply to any installations that are not "Stand-alone"
Where these rates are shown, the 'higher rate' prevails if neither of the following two conditions apply:
The 'lower rate' is payable where:
- The system provides power to a building, and
- The building does not have an EPC certificate showing its energy efficiency in bands A to D
The 'medium rate' is payable where:
- The system owner has a total of 25 FIT-registered PV installations
The medium rate is 90% of the higher rate (rounded to two decimal places)
This tariff is available only for 30,000 micro-CHP installations, subject to a review when 12,000 units have been installed.
Those systems that transferred to the FITs at the start of the scheme, having been originally registered under the RO receive a fixed rate whatever the technology and size.
