In early 2021, researchers at a university in Madrid recovered several bifacial PV modules manufactured by Spanish company Isofotón in 1987 that had been operating in different facilities. Following cleaning and characterization, 56 of the modules were installed on a fixed structure at the university, where they have been feeding energy into the grid since May 2021. pv magazine España’s Pilar Sanchez Molina visited the repurposed modules to tell their story.
Antecessor features 56 bifacial modules that are in very good condition despite being in use for more than 20 years.
