The development of bifacial modules has complicated the assessment of available solar resources. Irradiation arriving at the rear side of bifacial modules is mainly determined by albedo ...

“The albedo is a key input parameter for bifacial PV energy yield estimations, but best practices are not yet completely defined, and proper procedures for albedo measurement are still under debate.

giving a high albedo effect. For six months the Poles receive no solar energy due to the Earth’s orbit and tilt.

Sheppard’s team ran computer simulations showing that 2015 TG387’s orbit was stable throughout the life of the solar system and ... on assuming a moderate albedo (reflectivity of light ...
