Bifacial solar panels are perceived to be the technology of choice for next\ngeneration solar farms for their increased energy yield at marginally increased\ncost. As the bifacial farms proliferate around the world, it is important to\ninvestigate the role of temperature-dependent energy-yield and levelized cost\nof energy (LCOE) of bifacial solar farms relative to monofacial farms,\nstand-alone bifacial modules, and various competing bifacial technologies. In\nthis work, we integrate irradiance and light collection models with\nexperimentally validated, physics-based temperature-dependent efficiency models\nto compare the energy yield and LCOE reduction of various bifacial technologies\nacross the world. We find that temperature-dependent efficiency changes the\nenergy yield and LCOE by approximately -10 to 15%. Indeed, the results differ\nsignificantly depending on the location of the farm (which defines the\nillumination and ambient temperature), elevation of the module (increases\nincident energy), as well as the temperature-coefficients of various bifacial\ntechnologies. The analysis presented in this paper will allow us to\nrealistically assess location-specific relative advantage and economic\nviability of the next generation bifacial solar farms.\n
