The efficiency of bifacial photovoltaic panels is low

How efficient are bifacial PV modules?

Module efficiency: Bifacial PV modules are now available with up to 22% efficiencies, comparable to traditional monofacial modules. However, there is still room for improvement, and researchers are working on new cell technologies that could push the efficiency of bifacial modules to 25% or higher [46, 135].

What is the status of bifacial photovoltaic (PV) module?

TABLE 2. Status of bifacial photovoltaic (PV) module. The bifacial modules were first conceived in the 1960s and were deployed in applications such as space exploration, telecommunication, and rural electrification [25, 30]. However, economic and technical barriers kept them out of the mainstream.

Why are bifacial solar panels becoming more popular?

In the solar PV industry, bifacial PV modules are becoming increasingly popular. This is because, when compared to monofacial PV modules, the module can absorb radiation on both sides of the panels to generate electricity, increasing the energy yield per square area.

How can bifacial PV improve energy production?

Research and development efforts on bifacial PV should continue to emphasize improved efficiency in cells, module reliability and deployment configuration of bifacial arrays in a PV plant to co-optimize front-backside energy production during the entire day for fixed and tracking systems.

Do bifacial solar cells provide more power?

Bifacial solar cells encased in a glass/backsheet structure provide more power under standard test conditions (STC) than glass/glass PV bifacial modules. However, glass/glass PV modules with bifacial solar cells deliver extra power in outdoor settings due to absorption from the module's rear side.

Are bifacial modules more energy efficient?

Under optimum conditions, bifacial modules offer up to 30% more energy than conventional modules. Comparative assessments also demonstrate higher energy output from bifacial modules, especially on cloudy days, with low light intensity. Increasing ground reflectance (albedo) to 0.5 can further enhance the bifacial gain worldwide.
