Bifacial Photovoltaic Modules

Product Overview

Our bifacial photovoltaic modules represent the pinnacle of solar energy technology, designed to maximize energy yield by harnessing sunlight from both the front and rear sides of the panel. Unlike traditional monofacial modules, bifacial photovoltaic modules capture reflected and diffused light from the ground, surrounding surfaces, and even snow, delivering up to 30% higher power output in optimal conditions. Engineered with advanced N-type TOPCon cell technology, these modules achieve industry-leading efficiency levels exceeding 22.5%, making them ideal for large-scale solar projects worldwide.

Built to withstand harsh environmental conditions, our bifacial photovoltaic modules feature a robust frame and tempered glass on both sides, ensuring exceptional durability and minimal degradation over a 30-year lifespan. Certified to international standards including IEC 61215, IEC 61730, and UL 61730, they offer reliable performance in diverse climates, from deserts to snowy regions. As a trusted supplier in the international solar market, we provide bifacial photovoltaic modules tailored for utility-scale installations, commercial rooftops, and innovative agrivoltaic applications, empowering businesses to achieve sustainable energy goals with superior return on investment.

Technical Specifications

Application Scenarios

Bifacial photovoltaic modules excel in a wide array of deployment scenarios, leveraging their unique ability to generate power from both sides for enhanced performance. In utility-scale solar farms, they are mounted on elevated structures or white gravel albedo surfaces to maximize rear-side gains, achieving higher specific yields per hectare compared to monofacial alternatives.

For commercial and industrial rooftops, bifacial photovoltaic modules perform exceptionally on reflective or light-colored surfaces, such as metal roofs or concrete, boosting overall system output without additional footprint. In agrivoltaic systems, they allow simultaneous crop cultivation and energy production, with rear-side light supporting plant growth while capturing ground-reflected irradiance.

These modules are also suited for ground-mounted residential arrays in snowy regions, where reflected light from snow dramatically increases energy harvest. Offshore floating solar projects benefit from water reflections, and desert installations capitalize on sandy albedo. Their versatility extends to carports and canopies, where under-panel reflections from pavements enhance efficiency, making bifacial photovoltaic modules a strategic choice for diverse B2B solar integrations globally.

Advantages

Opting for our bifacial photovoltaic modules provides distinct advantages that set them apart in the competitive solar market. Firstly, their superior energy yield—up to 30% more than monofacial modules—translates to shorter payback periods and maximized land utilization, critical for large-scale developers.

With lower degradation rates thanks to N-type TOPCon technology, these modules maintain over 87% of initial power after 30 years, ensuring long-term reliability and predictable revenue streams. The double glass encapsulation offers unparalleled resistance to microcracks, moisture ingress, and potential induced degradation (PID), extending operational life in humid or coastal environments.

Additionally, bifacial photovoltaic modules demonstrate excellent temperature coefficients (-0.30%/°C for Pmax), performing better in hot climates. Their low-light prowess ensures consistent output during early mornings, evenings, or overcast days, optimizing grid integration. From an economic perspective, reduced BOS (balance of system) costs due to higher wattage per panel lower installation expenses. Environmentally, they support sustainable practices with recyclable materials and minimal ecological footprint, aligning with global ESG standards.

FAQ

What is the bifacial gain of these photovoltaic modules?
The bifacial gain typically ranges from 10-30%, depending on installation height, ground albedo, and tilt angle. For example, on high-albedo surfaces like white gravel, gains can exceed 25%.

Are bifacial photovoltaic modules suitable for all mounting types?
Yes, they perform best in ground-mounted or elevated systems but are also effective on reflective rooftops. Avoid direct ground contact to maximize rear-side exposure.

What warranties do you provide?
We offer a 12-year product workmanship warranty and a 30-year linear power output warranty, with degradation limited to under 1% in the first year and 0.4% annually thereafter.

How do bifacial modules handle snow or dust accumulation?
The rear glass design and self-cleaning properties reduce accumulation. In snowy areas, melted snow reflection further boosts output.

Are these modules compatible with existing inverters?
Absolutely. They feature standard MC4 connectors and operate within common string inverter voltage ranges (1000-1500V).

What certifications ensure quality?
Modules are certified to IEC 61215/61730, UL 61730, CE, and others, with full traceability via serial numbers.
