How Efficient Are Bifacial Solar Panels

Bifacial solar panels are not only efficient because of their ability to make use of reflective light but many other reasons also increase their effectiveness.

How efficient are bifacial solar panels.

Bifacial solar panels are not entirely new. Their neon 2 bifacial solar panels have an efficiency of up to 18 7. Bifacial solar panels for purchase. Whereas traditional opaque backsheeted panels are monofacial bifacial modules expose both the front and backside of the solar cells.

Korean electronics conglomerate lg is currently dominating the market by offering an energy efficient bifacial module with a front system of 390 w. These panels absorb sunlight from the front and rear. Some companies claim that up to thirty percent of increased efficiency is achievable. Because of this reason they re mostly more efficient than the traditional monofacial panels.

When bifacial modules are installed on a highly reflective surface like a white tpo roof or on the ground with light colored stones some bifacial module manufacturers claim up to a 30 increase in production just from the extra power generated from the rear. As the name suggests these panels efficiently absorb energy from both the front as well as the rear face. Bifacial solar technology however boasts better solar panel ratings. The average electrical output of solar panels ranges between 250 and 400 watts.

The ideal use case for bifacial solar panels is in commercial and utility scale solar installations especially those that utilize solar trackers. In a recent study conducted by longi a solar panel manufacturer bifacial panels yielded 11 percent more energy than standard solar panels in a tilted ground mounted solar installation in china. These solar panels have an average efficiency between 15 and 20 percent while premium solar modules have energy efficiencies of 23 percent.
