Price Development

The price development in facts is as follows (cf. Fraunhofer 2019, p. 10):

  • In Germany from 1990 to 2018 the average prices for a typical 10 to 100kWp PV rooftop-system decrease from 14€/kWp to 1.07€/kWp,
  • a net-price regression of  about 92% and
  • an annual compound average price reduction rate of 8%.
  • Due to the economies of scale and technological improvements, in the last 38 years the module price decreased 24% with each doubling of the cumulated module production.
