(author), Energieonderzoek Centrum Nederland (author)The lifetime of a PV module is critical for PV manufactures, developers and end-users as it directly affects the energy yield and so cost of a PV system. The standards IEC61215, 61646 and 61730 are considered excellent for identification of major design issues, but they do not include sufficient testing to be able to predict outdoor performance...conference paper 2014
