A new path to self-sustaining markets for PV

摘要

A new form of market development for photovoltaics is growing in Germany. "Rate-based incentives" allow the public to install PV power systems and recover their investment over time through a per kilowatt hour payment for clean energy generation. The payback is funded through a low surcharge on electric utility bills. The important aspect is there is no need for subsidies from the state, local authority or public utility with this system. The program has been implemented in cities where the public and the politicians support the idea of a utility bill surcharge to encourage the installation of photovoltaics. This paper provides the specifics behind the rate-based concept and its advantages for PV market development. In addition, the paper reviews the status of rate-based incentives in cities which have implemented the program and also looks at those cities which are considering the concept.
