During a workshop held at the International Solar Energy Society's recent conference in Kassel, Germany, several research institutes from Europe and the U.S. adopted a new draft for an outdoor test standard for photovoltaic modules.
With this standard, the project partners of the Network of Excellence DERlab (Distributed Energy Resources Laboratory) have created standardized international measurements for the long-term evaluation of solar modules under real-life conditions.
‘While the IEC standards consider specially the performance of partial aspects of the solar power plants, it is our objective to characterize the entire system in the future as a whole,’ says Roland Brundlinger, board chairman of DERlab. ‘Thus, we shortly plan to incorporate inverters in the testing as well.’
Comments on the draft standard will be accepted until Sept. 20. The standard is expected to be published in October.
