About Bifacial Solar Panels
Bifacial Solar Panels
A growing segment, especially for large-scale commercial and utility projects. They are a variation of monocrystalline technology.
How to Identify: They have a transparent backsheet and often a frameless design.
Technology: Can capture sunlight from both the front and the rear side. The rear side captures light reflected from the ground (e.g., white terrace, gravel).
Efficiency: Can produce 5% to 20% more energy than a standard monofacial panel of the same rated capacity, depending on reflectivity (albedo) of the surface beneath.
Pros:
Higher Energy Yield: Generate more power in the same footprint.
Durability: Often come with stronger frames and longer warranties.Often double-glass modules, making them more robust and longer-lasting.
Cons:
Higher Initial Cost: More expensive than standard mono panels.
Installation Specifics: Require elevated mounting (e.g., using raised structures) to allow light to reach the back, which can add to the cost.
Best For: Large commercial buildings, industrial sheds, solar carports, and ground-mounted systems where they can be installed high above a reflective surface.
Is Bifacial Worth It? Bifacial panels only make financial sense if you can create the conditions for them to generate extra power. This means:
Installing them on elevated structures (increasing mounting cost).
Having a highly reflective surface underneath (e.g., a white painted "Terrace Cool" coating, or a galvanized steel roof).
