With analyst predictions going as high as 40 GW for annual bifacial demand by 2023, it is imperative for stakeholders across the industry to understand the behavior of these modules in the field. Ground albedo and the way that diffuse and reflected light hits the rear side of the modules are the key concerns. A better understanding of these factors, gained from sophisticated yield-modeling simulations and bifacial test installations all over the world, has already helped to identify the challenges and opportunities in optimizing projects to maximize bifacial energy yield.
