Solar Bifacial Modules

Product Overview

Our solar bifacial modules represent the pinnacle of photovoltaic innovation, designed to capture sunlight from both the front and rear surfaces for maximized energy yield. Unlike traditional monofacial panels, solar bifacial technology harnesses reflected and diffused light, delivering up to 30% more power generation in optimal conditions. Engineered for international trade and large-scale deployments, these modules are ideal for commercial and utility-scale projects worldwide.

Solar bifacial panels utilize high-efficiency N-type TOPCon cells, ensuring superior performance even in low-light environments. With a bifaciality factor exceeding 80%, they excel on reflective surfaces such as white rooftops, ground-mounted systems with albedo-enhanced substrates, or snowy terrains. Our modules undergo rigorous testing to meet IEC 61215 and IEC 61730 standards, guaranteeing long-term reliability and minimal degradation—less than 0.4% annually.

Available in power outputs from 550W to 700W, these solar bifacial solutions are tailored for diverse climates, from arid deserts to temperate zones. Their transparent backsheet and optimized glass encapsulation allow seamless light transmission to the rear side, boosting overall system efficiency. For B2B partners in international trade, our solar bifacial modules offer a competitive edge through enhanced LCOE (Levelized Cost of Electricity) and rapid ROI, making them a cornerstone for sustainable energy portfolios.

Technical Specifications

Note: Specifications measured under STC (Standard Test Conditions: 1000 W/m² irradiance, 25°C cell temperature, AM 1.5 spectrum). Actual bifacial gain depends on installation environment and ground albedo.

Application Scenarios

Solar bifacial modules thrive in environments where rear-side irradiance is maximized. In utility-scale solar farms, they are deployed on single-axis trackers with high-albedo gravel or white membranes, yielding 15-25% additional energy compared to monofacial counterparts. For commercial rooftops, solar bifacial panels on reflective TPO or white gravel surfaces deliver superior urban energy harvesting.

In snowy regions, the elevated structure allows clean rear-side exposure, preventing snow accumulation losses. Agrivoltaic projects benefit from solar bifacial technology, combining crop cultivation under panels with elevated bifacial gain from ground reflection. Floating solar installations leverage water's high reflectivity, making solar bifacial an optimal choice for PV-water hybrids in reservoirs and aquaculture farms.

Off-grid and hybrid systems in deserts utilize solar bifacial modules to combat sand reflection and heat, ensuring consistent output. Their versatility extends to carports, canopies, and building-integrated photovoltaics (BIPV), where space constraints demand maximum efficiency per square meter.

FAQ

What is a solar bifacial module?
Solar bifacial modules generate electricity from both front and rear sides, utilizing direct, reflected, and albedo light for higher yields than monofacial panels.

How much extra power can solar bifacial panels produce?
Typically 10-30% more, depending on installation height, ground reflectivity (albedo), and tilt angle. Tools like PVsyst can model site-specific gains.

Are solar bifacial modules suitable for all installations?
Best for ground-mount, trackers, and reflective surfaces. Less ideal for dark rooftops or close-to-ground setups with low rear irradiance.

What maintenance do solar bifacial modules require?
Minimal; double-glass design is self-cleaning. Periodic inspection for framing integrity and electrical connections recommended.

Do solar bifacial panels work in shaded areas?
Yes, half-cut cells and high bifaciality mitigate shading losses better than traditional panels.

What warranties are offered?
12 years product workmanship, 30 years linear power output (84.95% at year 30), transferable globally.

Are custom sizes available for solar bifacial products?
Yes, we offer tailored dimensions and power ratings for specific project needs in international trade.
