| Abstract | Identification of failure mechanisms from the long-term field deployed modules is of great importance to the photovoltaic industry. This paper investigates the modules removed from a water pumping array operated over 27+ years in a hot-desert climatic condition, Arizona. Thirty-two modules were evaluated in this investigation. Each module is comprised of silicone rubber superstrate/encapsulant, mono-Si cells, fiberglass-like substrate, potted junction box and neoprene cable. Ten of these thirty-two modules were either non-functional or near non-functional with less than 30% of the original power. The other twenty-two functional modules showed an average power degradation of 1.08% per year over 27 years of operation. After the damp-heat (1000 hours of 85degC/85%RH), thermal cycling (two-hundred cycles of 90degC/-40degC) and hot-spot stress tests the modules lost about 11%, 9.8% and 3.5% of power, respectively |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
