Array Technologies is among several industry players looking to back bifacial’s promise with more data. Bifacial solar PV technology has long been a novelty. But pilots announced this summer — including a new Soltec bifacial tracker test center in California, plus a partnership between Array Technologies and a national lab in New Mexico — suggest bifacial is edging toward the mainstream. But manufacturers still need to dial back costs. Before bifacial modules are ready for widespread adoption, manufacturers say the industry has a year or two of data collection to determine how they compete in both efficiency and cost, and what applications they’re most effective for. “Once everyone understands the costs and the implications and can understand the problems, well, the problems get simplified,” said Array founder Ron Corio. “We’re in that simplification process right now.” The company recently installed two rows of bifacial modules — from manufacturers Longi, JA Solar, Trina, Jolywood, Hanwha Q Cells and Canadian Solar — at a New Mexico national laboratory to test the modules with its trackers and create simulation models from the test rows. Because bifacial modules collect sun from both the top and the bottom of the panel, they present unique […]
