Development of the solar duty

Unvarying tariffs, but from year to year more requisition at new buildings is the development target of the solar duty. Here a compare to the German EEG.

  EEG Germany Solar duty
for the system
Nearly like free market Government supported
Government security No Yes
Laufzeit Einspeisetarif 20 Jahre 20 Jahre
Delivery Tarif 2008 0,4675 EUR Etwa 0,16 bis 0,22 EUR
Delivery tariff 2020 for new systems 0,1541 EUR Dynamic 0,08 to 0,30 EUR
Average 0,16 to 0,22 EUR
Yearly change Less delivery tarfi
for new systems
More kWh yearly yield
minimal requisition for new buildings
Reason for the tariff development until 2020 Photovoltaic becomes cheaper By higher requisition have also less suitable roof and facade areas be used.
More cost because of storage duty.
Storage for solar electricity Not scheduled Scheduled as soon as lithium batteries reach an interesting price fot the task.
Target of the law Built up of the photovoltaic industry Plus energy house as standard
Electricity for electric mobility
Share at the electric power production 2020 2 to 3%
that is easy
without storage
15 to 20%
More than 10% solar share is only possible with more electric power storage.
Photovoltaic politics and furtherance
Further now, in order that when electric power from fossil energy costs 30 Cent per kWh, solr electric power costs only 25 Cent per kWh

  Solar duty

Study about the fast increase of electric power from photovoltaic. The German energy entry law is the best possible for 2004. The solar duty orients at the possibilities of 2008.

EEG Germany: It is difficult to bestow money
At the proclamation of the energy delivery low, there should have been immedeately long queues at every photovoltaic company to take the money present.

Germany EEG: credit problems
For German banks is a photovoltaic with 20 years energy delivery contract no security. At this fail 8 from 10 people interested in a photovoltaic. Solar duty guarantees the credit

Cheap thin film modules + synergy
The basics of the study for solar duty are cheap thin film modules replacing as synergy effect material for roof and and facade.

Comment about solar duty
Synergy effects by construction material replaced by photovoltaic and low modul prices make electric power from thin film photovoltaic cheap enough, to think about a duty.

Storage duty for solar electric power
In the final state will be 60% of the maximal daily yield be the minimu battery capacity. But even at the begin of the solar duty will be an appropriate sized place for the storage a duty.

Liberation from the solar duty
The government determines for each property the dimension of solar duty. By the furtherance, there is a highest price, where the system is cost neutral for the new house owner.
