Features
Unique Value Proposition
CD Solar BC Modules are designed to provide customers with higher power, higher return, and ultra-safe operation throughout the entire lifecycle.
● Better temperature coefficient
● Lower long-term degradation
● Superior partial shading optimization
● Higher energy density under the same installation area
Compared with conventional TOPCon modules, CD Solar BC Modules deliver 6–10% higher power output under the same rooftop area.
Higher Power Output
Full Light Absorption, Zero Front Shading
● All electrical contacts are placed on the rear side of the cell
● No front grid lines, maximizing effective light-receiving area
● Higher module power density within limited installation space
Higher Return Throughout Lifecycle
Excellent Temperature Coefficient
● BC temperature coefficient as low as –0.26% / °C
● Superior high-temperature performance compared with TOPCon (–0.29% / °C)
● Stable power generation in hot climates and high-irradiance regions
Lower Degradation
● Reduced power degradation over 25–30 years
● Long-term energy yield advantage verified by third-party test reports
Partial Shading Optimization
CD Solar BC Modules feature an optimized rear-side circuit design that significantly reduces mismatch losses.
● When a cell is fully shaded, BC technology can generate up to 30% more electricity than conventional TOPCon modules
● Ideal for complex rooftops, north-south slopes, and partially shaded environments
● Expands usable rooftop area and reduces site selection limitations
Ultra-Safe Performance
Lower Hot-Spot Risk
● Positive and negative electrodes located on the same side
● Lower reverse resistance and reduced hot-spot temperature
● More than 30% lower hot-spot temperature compared with TOPCon modules
Fire-Risk Reduction
● Improved current path design minimizes thermal concentration
● Enhanced safety for residential, commercial, and industrial rooftops
High Reliability & Mechanical Strength
Copper-Based Metallization
● Replaces traditional silver screen printing
● Lower cost, higher mechanical strength, and improved sustainability
Micro-Crack Resistance
● Single-sided soldering structure
● Better resistance to thermal stress, vibration, and mechanical load
● Maintains power generation even after minor cell fractures
Product Design & Aesthetics
● Grid-free, all-black front appearance
● Premium visual integration for high-end rooftops
● Available in monofacial and bifacial options
● Compatible with mainstream mounting systems and inverters
Application Scenarios
● Residential rooftops
● Commercial & industrial rooftops
● High-temperature regions
● Projects requiring maximum yield per square meter
