ASU Photovoltaic Reliability Laboratory (ASU-PRL, established in January 2009) is dedicated to performing PV reliability research. Its mission is to predict climate-specific and construction-specific lifetimes of PV modules by investigating actual field failure modes and mechanisms, accelerated lifetime testing (ALT), physics-based statistical models. Since its establishment, ASU-PRL has been funded by DOE, SFAz, Arizona Public Service (APS) and Salt River Project (SRP), the National Renewable Labs (NREL), Sandia National Labs, and the Electric Power Research Institute (EPRI). ASU-PRL has already performed field reliability evaluation of over 50 PV powerplants with more than 250,000 modules in four climates: Hot-dry; Temperate; Cold-dry; Hot-humid, and is currently funded to evaluate additional PV power plants in Arizona and New Mexico. In the last five years alone, ASU-PRL has generated more than 45 graduate students and published more than 60 papers on PV reliability in peer-reviewed conferences and journals.
Dr. Mani founded ASU-PRL in 2009 and has been serving as the director of ASU-PRL since then. He was the director of ASU-PTL between 1999 and 2008, and the president of TUV Rheinland PTL (a spin-off of ASU-PTL) between 2008 and 2015. He has more than 32 years of research and accelerated testing experience in photovoltaics. He has published and presented over 150 papers in journals, conferences and workshops. He holds a patent in PID control and prevention and a provisional patent in automated waterless soiling monitoring system. His current research interests include market-driven applied research addressing technology application issues and real-world reliability issues using field failure data and accelerated indoor testing data.
