Bifacial solar modules are a type of solar panel that can produce solar power from both sides of the panel. They use PERC technology that has significantly increased their efficiencies and created the potential for them to be a disruptive player in the solar PV market. However, there are many variables which must be addressed before bifacial modules can claim a significant market share. Cost is one of the biggest factors, particularly in the case of monofacial modules. The cost of bifacial modules has fallen precipitously over the last two decades. Notably, as costs have decreased, so too has the cost gap between mono- and bifacial modules. The extra production costs resulting from producing the rear side of bifacial modules can compensate for additional costs. But is increased production enough to cover the additional costs? The answer is: it’s complicated. While the increased cost of equipment and installation costs of bifacial PV plants are not excessive, there are other factors preventing widespread adoption. Results and studies have shown that bifacial modules can produce additional power between 10-20% over monofacial panels. If conditions are optimized and single-axis trackers adopted, the additional power can be as high as 30-40%.
