Bifacial modules carry a $0.006-0.010/W premium over monofacial in 2026. That's a 5-8% CapEx uplift for a 4-14% energy yield gain — but the payback depends heavily on albedo, tilt and tracker use.

When bifacial pays back
Bifacial+tracker on high-albedo ground (sand, concrete, snow, white gravel) always pays back inside 18 months. Bifacial+fixed-tilt on green grass or dark soil often doesn't — the premium exceeds yield gain over 25 years.
Frequently asked questions
QWhat about rooftop bifacial?
Only worth it on white-membrane commercial roofs. On dark asphalt or shingles, monofacial wins.
