🔄 Double the Power: The Innovation of Two-Sided Solar Cells

Bifacial panels capture direct sunlight on the front and reflected light (albedo) on the back, offering a significant efficiency boost.

1. How Bifacial Technology Works

Unlike traditional panels with an opaque backing, bifacial panels use clear backsheets and double glass construction.

• ✅ **Albedo Effect:** They capture light reflected off the roof surface, ground (grass, dirt), or snow.
• ✅ **Output Gain:** Depending on the surface underneath and the height of the mounting, bifacial panels can generate **5% to 30% more power** than traditional mono-facial panels.

2. Where Bifacial Excels (and Where It Doesn't)

The mounting location is key to maximizing reflected light capture.

• **Ground Mounts:** Ideal, especially when mounted high over a light-colored surface (white gravel, concrete, or snow).
• **Flat Roofs:** Excellent choice for commercial buildings where the white TPO roof reflects light perfectly.
• **Pitched Residential Roofs:** Less effective due to limited space between the panel and the shingles, minimizing reflected light capture.

Durability Advantage

Because bifacial panels often use a double-glass design, they are inherently more resistant to potential induced degradation (PID), moisture intrusion, and micro-cracking, often leading to a stronger 30-year warranty. 💡
