High-Efficiency Bi Facial Solar Panel for Commercial & Utility-Scale Projects

In the pursuit of maximizing energy yield and return on investment, forward-thinking project developers are turning to advanced photovoltaic technology. Our premium bi facial panel represents the next generation in solar energy harvesting, engineered to capture sunlight from both the front and rear sides. Designed for demanding commercial, industrial, and utility-scale applications, this module delivers superior performance, exceptional durability, and a significantly enhanced energy output compared to traditional monofacial panels.

Product Overview

Our bi facial solar panel utilizes high-purity monocrystalline PERC cells and dual-glass construction to achieve remarkable bifaciality. Unlike conventional panels, it generates power not only from direct and diffuse irradiance on its front surface but also from light reflected onto its rear side from the ground or surrounding surfaces. This innovative design is encapsulated between two tempered glass sheets, ensuring a robust, frameless structure that is resistant to environmental stressors, including PID, humidity, and mechanical load. It is the optimal solution for installations where albedo (ground reflectivity) can be leveraged, such as on white membranes, light-colored gravel, or elevated ground-mounted systems.

Key Features

• Dual-Side Power Generation: Captures reflected and diffused light from the rear, boosting total energy yield by up to 30% under optimal conditions.
• Robust Dual-Glass Design: Frameless construction with two layers of tempered glass provides superior mechanical strength, long-term reliability, and excellent resistance to potential-induced degradation (PID).
• High Bifaciality Factor: Features a bifaciality factor exceeding 70%, ensuring efficient rear-side energy conversion.
• Lower Levelized Cost of Energy (LCOE): Increased energy production per panel directly translates to a lower cost of electricity over the system's lifetime.
• Enhanced Durability: Withstands high wind and snow loads (up to 5400Pa), and the glass-glass construction minimizes degradation for a extended power warranty.
• Low Light & High Temperature Performance: Advanced cell technology ensures stable performance in low-light conditions and reduced power loss at high temperatures.

Technical Specifications

Application Scenarios

The unique advantage of a bi facial panel is fully realized in specific installation environments that maximize rear-side irradiance. Key application scenarios include:

• Ground-Mounted Solar Farms: Elevated mounting systems (single-axis trackers or fixed-tilt) over highly reflective surfaces like sand, concrete, or white painted gravel.
• Commercial & Industrial Rooftops: Installation on flat roofs with high-albedo membranes or ballasted, raised mounting systems.
• Carport & Canopy Structures: Ideal for solar carports where light reflects from the ground below, providing both shade and clean energy.
• Noise Barriers & Vertical Installations: Deployed along highways or as building-integrated photovoltaics (BIPV) on facades.
• Agricultural Agrivoltaics: Mounted high above crops, allowing dual land use while benefiting from ground reflection.

Advantages Over Conventional Panels

Choosing a bifacial solar solution offers tangible benefits for large-scale energy projects:

• Higher Energy Density: Achieve more watt-hours per installed watt-peak (Wh/Wp), optimizing land or roof space usage.
Improved ROI: The additional energy yield accelerates payback periods and increases the financial return over the system's 30+ year lifespan.
• Superior Reliability: The dual-glass, frameless design eliminates corrosion risks, prevents water ingress, and offers better resistance to harsh weather, leading to a lower degradation rate.
• All-Weather Performance: The rear side can capture light reflected from snow cover or during early morning/late afternoon hours, smoothing the daily power generation curve.
• Environmental Sustainability: Often utilizes lead-free soldering and fully recyclable materials, aligning with corporate sustainability goals.

Frequently Asked Questions (FAQ)

How much extra energy can a bi facial panel produce?

The bifacial gain depends heavily on installation factors: albedo (ground reflectivity), mounting height, tilt angle, and geographic location. Gains typically range from 5% to 30% over traditional monofacial panels. A system installed on a white membrane rooftop or elevated over light-colored gravel will see higher gains.

Is a special mounting system required for bifacial modules?

Yes, to allow light to reach the rear side, mounting systems should be elevated and use non-obstructive rails. Single-axis trackers are highly recommended as they optimize both front and rear irradiation throughout the day. We provide compatible mounting recommendations.

Are bifacial panels more expensive?

While the initial cost per panel may be slightly higher, the Levelized Cost of Energy (LCOE) is often lower due to the significantly higher energy yield over its lifetime. This makes them a more cost-effective solution on a $/kWh basis for large-scale projects.

How do you calculate the expected energy yield for a bifacial system?

We use advanced simulation software (like PVsyst) that incorporates bifacial modeling, using your specific site data—including albedo values, array configuration, and mounting details—to provide a precise energy yield forecast and financial model.

Do you provide technical documentation and performance warranties?

Absolutely. Each shipment includes full technical datasheets, IEC certificates, and a comprehensive warranty package. Our 30-year linear performance warranty guarantees a minimum of 92% output in the first year and a degradation of no more than 0.45% annually, ensuring long-term performance.
