Experience curve approach for more effective policy instruments

The price evolution of PV systems in Europe shows that a significant reduction is achieved for modules and the BOS of small rooftop grid connected systems. The learning rate is 20%, consistent with other studies. The module price has stabilised the last years, as market conditions had a large effect. It is expected that recently built and planned module production facilities will give an increased cost reduction. For rooftop systems the market that has been created in the last decade will lead to more standardisation and integration in the building sector, leading to lower prices, but also more application.
