Bifacial Solar modules can capture sunlight from both sides as opposed to one in case of traditional PV modules. This allows bifacial modules to reflect sunlight from behind the panel to increase energy production, with estimates claiming up to a 5-15% jump, depending upon the type of installation.
Bifacial Solar modules for Commercial and Industrial (C&I) applications
In commercial and utility-scale applications, panels are elevated and angled away from the mounting surface allowing light that strikes the ground to reflect back upwards enabling bifacial cells to absorb greater sunlight. Essentially, with bifacial modules, there are now two optimal sun hours (peak hours) of the day opposed to just one because of the dual sides. Thus, generating greater energy yield without having the need to occupy additional space.
In general, surfaces that are lighter in color like fine sand and marble can cause more sunlight to be reflected than darker surfaces like asphalt. Therefore, the use of bifacial panels in sandy deserts can generate maximum energy output.
Bi-facial PV module is the new buzz word in the Solar industry and seems like a promising technology for 2020. Other than the energy production benefits, bifacial modules also come with sleeker aesthetics and versatile system designs.
