Albedo is one of the crucial variables in the energy estimation for bifacial photovoltaic modules due to the modules’ ability to collect electricity from both front and rear sides. There are several modeling tools for the energy estimation of these modules. Our paper reports on the comparison of available energy estimation models with view factor and ray tracing and compares the estimated data with real measured values.
