Japan and Germany rank first and third in the world, respectively, in terms of installed photovoltaics (PV) capacity. Most of Japan's capacity has been installed through a residential buy-down program (supplemented, to some degree, with low-interest loans). Germany has used a number of approaches to stimulate PV development, including rebates, low-interest loans, and premium feed-in tariffs that combine a high incentive level and a mandatory purchase requirement by utilities. This case study briefly describes PV support programs in Japan and Germany. Innovative Features
Results Both Japan and Germany demonstrate that various combinations of low-interest loans and buy-down programs can work over extended periods.
