As a partial result, a study has been released. Ulrike Jahn, project leader at TÜV Rheinland, explains that: “For the first time we have been able to record and assess all economic risks concerning PV plant components over the total lifetime of PV plants”. The study addresses all phases in the lifecycle of a PV plant, from the development of parts and products and the planning of the plant to transport, installation and finally to operation and decommissioning. Jahn stresses that “what is special about this project, is the economic evaluation of the individual risks. The quantitative cost for each failure type has been specified.” Thus, it is possible to calculate the financial losses caused by the various risks in Euro per watt. These results will be discussed with experts in a public workshop, which takes place in Cologne on 09-10 May, 2016. Interested persons can register at http://www.tuv.com/en/corporate/up_to_date/solar_energy/solar-bankability-workshop-2016.html (first come, first served).

The next goal is to develop and evaluate measures for minimizing these risks. Within the scope of the Horizon 2020 programme, the research project is funded under project reference number 649997.
