PV module performance over time: assessing 26 years at the HSU Telonicher Marine Lab

In 1990, the Schatz Center installed 192 ARCO M75 photovoltaic (PV) modules at the HSU Telonicher Marine Lab in Trinidad, California, 150 m off the Pacific Ocean. Current voltage (IV) tests were performed on each module prior to the array’s construction in 1990, again in 2001 and 2010, and most recently in 2016 after the array was decommissioned.
