Does reflector affect bifacial PV module?
A similar simulation study was conducted to observe the effect of reflector for bifacial PV module (Reagan and Kurtz, 2022), but these studies were analyzed by placing reflector only on one side of the PV array.
What is bifacial solar photovoltaics (PV)?
Enhancement of power generation of the PV array by up to 57% for the fall equinox. 51% increase in power for the entire year as compared to a system without mirrors. Bifacial solar photovoltaics (PV) is a promising advanced technology that uses light absorption from both sides of PV modules to improve the power output produced per square meter.
How bifacial photovoltaic (PV) modules enable higher power output?
Abstract: Bifacial photovoltaic (PV) modules enable higher power output in the installed systems by using additional light reflected on the back of the cells. Conventionally, the light reflected from the ground surface is used by the bifacial PV systems.
How does albedo/reflected radiation affect the power generation of PV panels?
Albedo/reflected radiation modifies the spectrum of the input light reaching the surface of the PV module, which, in turn, alters the system output. Researchers have developed several strategies to increase the power generation of installed PV panels including the usage of reflector (Rizk and Nagarial, 2009; Agrawal et al., 2022).
Can reflecting mirrors increase power generation from vertically mounted bifacial PV modules?
From this perspective, we propose a novel technique to increase the power generation from both sides of vertically mounted bifacial PV modules by using reflecting mirrors. The reflected irradiance incidence on the PV modules increased by approximately 10 times when reflecting mirrors were used.
Is a reflector more expensive than a PV module?
The system power generation through a reflector is less expensive than employing additional PV modules to produce the equivalent amount of power (Seitel, 1975; Dallakyan and Vardanyan, 2007 ). Stacey et al. analyzed the effect of concentration on the performance of plat fate PV modules ( Stacey and McCormick, 1984 ).
