Bifacial Solar Panels
Bifacial solar panels generate electricity from both sides, making them ideal for commercial roofs, carports, ground mounts, and farms where maximizing energy output per square foot matters. For U.S. property owners and installers, they offer a practical way to increase energy yield on reflective or space-constrained sites without expanding the array footprint.
How Bifacial Solar Panels Work?
What is a bifacial solar panel? A bifacial solar panel exposes solar cells on both sides to capture direct sunlight on the front and reflected or diffused light on the back. This design delivers roughly 10–30% more energy than comparable monofacial systems. Modern bifacial modules predominantly utilize N-type TOPCon technology, which offers a significantly higher bifaciality factor (the ratio of rear-to-front power) compared to older P-type PERC cells.
Instead of an opaque backsheet, bifacial modules use glass-glass or glass-transparent construction, allowing light reflected from concrete, white roofs, snow, gravel, or light soil to reach the rear cells. This dual-side harvesting improves output throughout the day, especially under low-light and diffuse conditions common on overcast days or in higher latitudes.
Benefits for Commercial Sites
For commercial properties, farms, and large homes, bifacial panels maximize production within the same racking and interconnection limits. When rear-side gain increases energy output by 10–15%, it improves ROI and lowers levelized cost of energy, particularly where demand charges and high daytime loads are factors. The transition to N-type cells also ensures lower degradation rates over the system's lifespan.
💡 Bifacial technology works especially well with elevated ground mounts between crop rows, agrivoltaic systems, warehouse roofs with white TPO membranes, and carports where paved surfaces act as reflectors.
Available Options on A1 SolarStore
The bifacial range covers high-power modules for retail buyers, pallet orders for mid-size projects, and full container quantities for developers. Power classes span from 440–450 W to 660 W and above, with 108‑cell and 132/144‑cell monocrystalline designs for rooftop and ground-mounted systems.
Retail Options
Single-project needs include bifacial modules like a 580 W SolarSpace 144‑cell panel and a 535 W JA Solar module, allowing installers to source high-efficiency units without full pallet orders.
Bulk Orders
Pallets and container lots from SolarSpace, ZNShine, GreenWatts, Phono Solar, Hounen Solar, and Philadelphia Solar with VOC values of 45–52 V and 31–36 panels per pallet or 560–936 panels per container.
Bifacial vs Monofacial Comparison
The main differences appear in energy yield, mounting requirements, and project economics. While monofacial modules suit many residential rooftops, bifacial units excel where mounting height, reflectivity, and layout optimize rear-side contribution.
Performance and Design
| Parameter | Bifacial (N-type TOPCon) | Monofacial |
|---|---|---|
| Light capture | Front plus rear side; uses direct, diffuse, and reflected light | Front side only; reflected light has minimal effect |
| Energy gain | 10–30% extra; higher bifaciality vs PERC | Baseline output at nameplate rating |
| Best conditions | Reflective surfaces, elevated mounting, wide row spacing | Standard roofs and ground mounts where rear is shaded |
| Layout needs | Higher tilt and clearance maximize rear irradiance | Designed for front-side irradiance and roof constraints |
| Lifetime yield | Higher kWh and lower degradation (0.4% annually) | Lower capex per watt but less kWh per square foot |
For U.S. commercial and agricultural projects, bifacial modules' ability to increase kWh per inverter input often outweighs their modest premium. This effect intensifies on high-albedo sites like snow-prone regions, light gravel yards, or white-coated flat roofs.
Installation Configurations
Bifacial modules on white TPO or reflective coatings benefit from rear-side irradiance while staying within ballast and wind load constraints. Higher tilt angles and adequate row spacing help the rear side capture more roof surface reflection.
Carports are natural hosts for bifacial technology because the array underside faces concrete or asphalt that reflects incident light.
Elevated bifacial racks above crops or pasture spread shade evenly and use reflected light from soil or groundcover. Studies show such designs increase energy harvest while preserving agricultural productivity.
Key Considerations for Decision-Makers
For CFOs, facility managers, and project developers, key variables include structural limits, interconnection caps, and how extra kWh translates to value over a 25 year asset life. Glass-glass bifacial modules often exhibit lower degradation and better mechanical robustness, enhancing lifetime yield.
Evaluate reflective surfaces and mounting height to estimate rear-side gain potential.
Include rear-side irradiance, local climate, and snow or soiling patterns in detailed modeling.
Calculate lifetime kWh improvements and LCOE reduction to justify the premium.
Treat bifacial panels as a design variable that drives racking height, tilt, and row spacing. Only an integrated design approach reliably captures the 10–30% rear-side gain documented in field data. For large commercial and agricultural systems, using high-efficiency N-type cells transforms bifacial technology into measurable cash flow improvements.
