Development of the solar duty

Unvarying tarifs, 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.

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 tarif 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 tarif 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.
