Bifacial solar panels use solar cells that can absorb light from both the front and rear surfaces. The front side captures direct sunlight like any standard panel, while the transparent or semi-transparent backsheet allows the rear cells to capture reflected light (albedo) from the ground, roof surface, or surrounding environment.
The amount of extra energy (bifacial gain) depends on several factors: the reflectivity of the surface below (white surfaces reflect 60-80%, grass reflects 20-25%, dark asphalt reflects only 5-10%), the height and tilt of the panel, and the spacing between rows. Ground-mounted systems with adequate clearance over reflective surfaces see the highest gains (15-30%), while flush-mounted rooftop installations see more modest gains (5-10%).
Most modern bifacial panels use N-type cells (TOPCon, HJT, or IBC/back-contact), which offer lower light-induced degradation and better temperature performance compared to traditional P-type PERC cells. This makes bifacial panels not only more productive but often more durable over their 25-30 year lifespan.
Frequently Asked Questions
What is a bifacial solar panel?
A bifacial solar panel generates electricity from both its front and rear sides. The front captures direct and diffuse sunlight, while the rear captures light reflected off the ground or roof surface (albedo). This dual-sided design can produce 5-30% more energy than monofacial panels under optimal conditions, making them increasingly popular for both residential and commercial installations.
Are bifacial solar panels worth the extra cost?
Bifacial panels typically cost 5-15% more than comparable monofacial panels, but the 5-30% energy gain can make them more cost-effective over their lifetime. They are especially worth it when installed over highly reflective surfaces (white roofs, light gravel, snow), on ground mounts with adequate clearance, or in locations with significant diffuse light. The ROI depends on your specific installation conditions and the bifacial gain you can achieve.
What is bifacial gain and how much can I expect?
Bifacial gain is the percentage of additional energy produced by the rear side of the panel compared to the front side alone. Typical gains range from 5-10% for rooftop installations to 10-30% for ground-mounted systems with reflective surfaces. The gain depends on ground albedo (reflectivity), panel height, tilt angle, and row spacing. White surfaces can yield 20-30% gain, while dark soil or asphalt may yield only 5-10%.
Can I install bifacial panels on a regular roof?
Yes, bifacial panels work on regular roofs, though the bifacial gain will be modest (5-10%) since standard roofing materials have low reflectivity. The panels still perform at least as well as monofacial panels from the front side. For maximum bifacial benefit on a roof, consider using a light-colored or white roofing material, or install the panels on a racking system with some clearance above the roof surface.
Which brands make the best bifacial solar panels?
Leading bifacial panel manufacturers include LONGi (Hi-MO 7 series), JinkoSolar (Tiger Neo), Trina Solar (Vertex N), Canadian Solar (BiHiKu7/TOPBiHiKu7), REC (Alpha Pure series), Maxeon (Maxeon 6/7), and JA Solar (DeepBlue 4.0 Pro). The best choice depends on your budget, efficiency requirements, and warranty preferences.
