High-Efficiency PV Bifacial Solar Modules for Utility-Scale & Commercial Projects

1. Product Overview

Our latest generation of PV bifacial solar modules represents a paradigm shift in energy generation efficiency. Unlike traditional monofacial panels that only capture direct sunlight from the front, these dual-glass modules harness reflected light (albedo) from the ground, snow, or roof surfaces, boosting total energy yield by 10% to 30% without increasing the footprint. Engineered for demanding B2B environments, this series combines N-type TOPCon cell technology with robust bifacial architecture to deliver superior performance under low-light conditions, high temperatures, and challenging terrains.

Each module is subjected to rigorous IEC 61215 and IEC 61730 certification tests, ensuring a linear power output warranty of 30 years. For project developers seeking to maximize ROI on large-scale solar farms, rooftop arrays, or carport installations, this PV bifacial solution is the definitive choice for sustainable, long-term power generation.

2. Key Features

• Dual-Glass Bifacial Design: Transparent backsheet combined with 2.0mm heat-strengthened glass on both sides allows rear-side gain of up to 25% over standard modules, effectively utilizing reflective surfaces like white gravel, sand, or single-ply roofing membranes.
• N-Type TOPCon Technology: Zero LID (Light-Induced Degradation) and lower temperature coefficient (-0.30%/°C) ensure stable power output even in hot climates, with first-year degradation as low as 1% and linear degradation of 0.40% per year thereafter.
• Enhanced Durability & Reliability: Certified for 5400 Pa snow load and 2400 Pa wind load. The dual-glass structure provides superior resistance to micro-cracks, PID (Potential-Induced Degradation), and moisture ingress, making it ideal for high-humidity or coastal regions.
• High Efficiency & Power Density: Module efficiency exceeding 22.5% with power output ranging from 580W to 620W, reducing balance-of-system (BOS) costs by requiring fewer modules and less mounting hardware per megawatt.
• Black Frame Aesthetics: Optional anodized aluminum black frame with hidden busbars for a sleek, uniform appearance—perfect for commercial rooftops where visual appeal matters.

4. Application Scenarios

• Utility-Scale Solar Farms: Deploy on ground-mounted tracking systems with high-albedo surfaces (e.g., light-colored gravel or reflective ground cover) to maximize rear-side gain. The PV bifacial modules deliver up to 30% more energy per acre compared to standard panels.
• Commercial & Industrial Rooftops: Ideal for flat roofs with white TPO/PVC membranes. The dual-glass construction eliminates the risk of hot spots from reflected light, while the black frame option blends seamlessly with modern architecture.
• Solar Carports & Canopies: Mounted at a tilt angle, the rear side captures light reflected from parked vehicles or the ground, creating a self-shading structure that also reduces cooling loads for buildings.
• Agrivoltaics: Elevate modules above crops or grazing land. The translucent backsheet allows diffused light to reach plants below, while the bifacial feature captures ground-reflected light, doubling land-use efficiency.
• Cold-Climate & Snowy Regions: Snow cover on the ground increases albedo dramatically. The PV bifacial modules can generate significant energy from reflected sunlight even when the front side is partially covered by snow.

5. Advantages

• Higher Energy Yield per Watt: Bifaciality combined with N-type cells translates to a levelized cost of energy (LCOE) reduction of 5–10% compared to standard monocrystalline modules.
• Reduced Degradation & Longer Lifespan: The absence of a polymer backsheet eliminates the primary failure mode of traditional modules. Dual-glass construction ensures consistent performance over 30+ years.
• Lower BOS Costs: Higher wattage per module means fewer panels, less racking, and lower installation labor costs per megawatt.
• Superior Performance in Diffuse Light: TOPCon cells maintain high efficiency under overcast skies or early morning/late afternoon conditions, ensuring stable power generation throughout the day.
• Environmentally Friendly: Lead-free construction and recyclable glass/aluminum frames align with global ESG (Environmental, Social, and Governance) standards.

7. FAQ

Q: How much extra energy can I expect from a PV bifacial module compared to a standard module?

A: Energy gain depends on ground albedo and mounting configuration. On a typical white gravel ground with a 1-axis tracker, you can expect a 15–25% increase in annual energy yield. On a dark roof (low albedo), the gain is typically 5–10%. We provide a free albedo analysis with your project proposal.

Q: Do PV bifacial modules require special inverters or wiring?

A: No. They operate with standard string inverters or microinverters. However, because the rear side can generate up to 25% additional current, we recommend using cables and connectors rated for a higher current (e.g., 4mm² or 6mm² cables) to minimize resistive losses. Our technical team can advise on the optimal configuration.

Q: Are these modules suitable for high-temperature environments like deserts?

A: Absolutely. The N-type TOPCon cells have a lower temperature coefficient (-0.30%/°C) than PERC cells (-0.35%/°C), meaning they lose less efficiency in heat. Additionally, the dual-glass construction dissipates heat more effectively than modules with a polymer backsheet, reducing operating temperature by 2–3°C.

Q: What is the minimum order quantity (MOQ)?

A: For standard black-frame models, MOQ is 1 pallet (31 modules). For custom configurations (e.g., specific voltage or frame color), MOQ is 1 container (typically 600–700 modules). We also offer sample orders for qualification testing.

Q: How do you ensure the modules are not damaged during shipping?

A: Each module is packed in a reinforced cardboard box with foam corner protectors, then stacked on heavy-duty pallets with corner brackets. The entire pallet is shrink-wrapped and secured with strapping bands. We have a 0.01% damage rate in transit, and any claims are handled within 48 hours.

Q: Can I use these modules on a residential roof?

A: Yes, but they are designed for larger commercial/utility systems. For residential applications (typically 400W–500W modules), we recommend our residential-specific bifacial series (contact our sales team for details). The 580W+ modules are best suited for homes with very large roof areas or ground-mounted systems.
