U.S.-Spanish researchers have proposed a new way to assess the reliability of PV modules and their warranties. It is impossible to fulfill a 25-year warranty if the threshold of returned modules exceeds 5% and the annual degradation rate is over 0.73%.Researchers from Spain's Universidad Politécnica de Madrid (UPM) and the Massachusetts Institute of Technology (MIT) have created a probabilistic model to assess the reliability of PV modules and their warranties. They described their findings in "Warranty assessment of photovoltaic modules based on a degradation probabilistic model," which was ...Den vollständigen Artikel lesen ...
