High-Efficiency Bifacial Solar Module for Commercial & Utility-Scale Projects
Introducing our next-generation solar module bifacial, engineered to maximize energy yield and deliver superior return on investment for large-scale solar installations. By capturing sunlight on both the front and rear sides, this advanced photovoltaic solution significantly outperforms traditional monofacial panels, particularly in environments with high albedo. Designed for durability and long-term performance, our bifacial modules are the optimal choice for developers, EPCs, and IPPs seeking to reduce levelized cost of energy (LCOE) and enhance project profitability.
Product Overview
Our solar module bifacial represents a leap forward in photovoltaic technology. Utilizing high-efficiency monocrystalline PERC cells and a transparent backsheet or dual-glass construction, these modules convert direct, diffuse, and reflected light into usable electricity. The core innovation lies in its ability to generate additional energy from light reflected off the ground or surrounding surfaces (albedo), such as white gravel, sand, snow, or specialized reflective membranes. This dual-sided power generation capability makes it an indispensable asset for ground-mounted solar farms, carport canopies, and agrovoltaic systems where space optimization and maximum energy harvest are critical.
Key Features
- Dual-Side Power Generation: Captures direct sunlight on the front and utilizes reflected light on the rear, boosting total energy output by up to 30% depending on installation conditions.
- Robust Dual-Glass Construction: Featuring tempered glass on both sides for exceptional mechanical strength, improved resistance to PID (Potential Induced Degradation), and a longer operational lifespan exceeding 30 years.
- Enhanced Low-Light Performance: Advanced cell technology ensures stable and efficient power production during early morning, late evening, and overcast conditions.
- Superior Durability: Withstands harsh environmental stresses, including high wind loads (up to 5400Pa), heavy snow (up to 5400Pa), and humidity, backed by a comprehensive product and performance warranty.
- Optimized for High-Albedo Environments: Delivers maximum bifacial gain when installed over light-colored, reflective surfaces, unlocking higher energy density per installed capacity.

FAQ
How much extra energy can a bifacial module produce?
The bifacial gain varies from 5% to 30%, primarily dependent on ground albedo (reflectivity), installation height, racking configuration (tracker vs. fixed-tilt), and geographic location. A professional site-specific simulation is recommended for accurate yield prediction.
Is special mounting required for bifacial modules?
Bifacial modules can be used with standard mounting systems, but to maximize rear-side gain, it is advised to use racking with minimal rear shading (e.g., single central rail or specific tracker designs) and to elevate the modules higher from the ground.
Are bifacial modules more expensive?
While the initial cost per module may be slightly higher than monofacial equivalents, the significantly higher energy output over the system's lifetime results in a lower LCOE, providing a superior financial return.
How do I model the performance of a bifacial system?
Advanced PV simulation software (like PVsyst) now includes dedicated bifacial modeling tools. Accurate modeling requires inputs for albedo, array layout, mounting structure geometry, and site weather data.
What surfaces provide the best albedo for bifacial gain?
Light-colored surfaces like white gravel, concrete, sand, and specialized reflective films offer high albedo (0.5-0.7). Fresh snow provides the highest albedo (~0.9), while grass and asphalt are lower (0.1-0.25).
