The feed-in tariff system has been modified frequently. The feed-in tariff, in force since 1 August 2004, was modified in 2008.10 In view of the unexpectedly high growth rates, the depreciation was accelerated and a new category (>1000 kWp) was created with a lower tariff. The facade premium was abolished. In July 2010, the Renewable Energy Sources Act was again amended to reduce the tariffs by a further 16% in addition to the normal annual depreciation, as the prices for PV panels had dropped sharply in 2009.11 Another modification of the EEG occurred in 2011, when part of the degression foreseen for 2012 was brought forward to mid-2011 as a response to unexpectedly high installations in the course of 2010.12
The support duration is 20 years plus the year of project commissioning, constant remuneration. Feed-in tariffs was lowered repeatedly (decreasing by 9% default and a maximum of 24% per year). Degression will be accelerated or slowed down by three percentage points for every 1000 MWp/a divergence from the target of 3500 MWp/a.
As of July 2014, feed-in tariffs for photovoltaic systems range from 12.88 ¢/kWh for small roof-top system, down to 8.92 ¢/kWh for large utility scaled solar parks. Also, FiTs are restricted to PV system with a maximum capacity of 10 MWp. The feed-in tariff for solar PV is declining at a faster rate than for any other renewable technology.14
Main article: German Renewable Energy Sources Act
On 1 August 2014, a revised Renewable Energy Sources Act entered into force. Specific deployment corridors now stipulate the extent to which renewable energy is to be expanded in the future and the funding rates (feed-in tariffs) gradually will no longer be fixed by the government, but will be determined by auction. Wind and solar power are to be targeted over hydro, gas (landfill gas, sewage gas, and mine gas), geothermal, and biomass. In late 2015, this new scheme is being tested, as a pilot project, for ground-mounted PV installations.17 With the Renewable Energy Sources Act (2017), auctions will become commonplace for new installations also for most other types of renewables.
