Photovoltaic Module Reliability || What does the Future Hold for PV and a Brief Summary
摘要： The discussions in the previous chapters looked at both the history and present‐day status of photovoltaics (PV) module reliability and the accelerated stress testing associated with it. In this final chapter, the focus will shift to the future. PV is a dynamic industry so the technology and the testing standards are constantly evolving. The first section in this chapter will provide an update on the changes already in progress for some of the more important module qualification and safety standards. The second section will switch to a longer‐range view, discussing how PV module reliability is likely to change in the future and what sort of accelerated stress testing will be necessary to validate the quality of the huge volume of modules produced. The book will end with a brief summary of the status of PV module reliability today.

Reliable long-term performance assessment of commercial photovoltaic modules tested under field conditions over 5 years
摘要： Due to their scalability and global abundance of sunlight, photovoltaic panels are a promising option as a renewable energy source. Implementation of photovoltaic technologies on a large scale requires a careful business-case assessment, aimed at the selection of the technological option most appropriate for the local conditions in terms of long-term performance. For this purpose, five types of modules representative of current options on the market were tested under field conditions for five years at a test facility in Germany. The degradation rates of module performance were computed from the obtained photovoltaic power normalized by both recorded and modeled solar irradiance. The results emphasize the relevance of using modeled irradiance data in addition to recorded solar irradiance in order to extract reliable degradation rates. The available methodological tools still have to be adapted to every dataset for the most accurate result. Eventually, robust degradation rates were extracted from experimental power data, based on modeled clear-sky irradiance, and a combination of aggregation and regression strategies. The results show distinctive degradation behaviors of the five available commercial photovoltaic modules in response to the local conditions.

The Value of Efficiency in Photovoltaics
摘要： Here, we introduce the value of efficiency (VOE), a metric that determines the maximum allowable cost for an innovation to improve the levelized cost of electricity. We use this metric to analyze historic, regional, and technological trends. We find indications for a stronger regional and sectoral market diversification. One example is tandem solar cells that could help to reduce electricity costs in US residential installations. We highlight the need for new PV technologies, like perovskites, to match leading technology degradation rates.
