Model MB_B120AyB_385 | 120 Half-Cut Mono N-Type HJT Cells | SWCT® | 367.6W PTC | 25/25 Warranty
Experience premium German-engineered solar technology with the Meyer Burger Black MB_B120AyB_385, a high-performance module featuring advanced Heterojunction (HJT) cell technology with patented SmartWire Connection Technology (SWCT®). This 385W all-black panel utilizes 120 half-cut N-type monocrystalline HJT cells to deliver exceptional 20.9% module efficiency in a sleek, aesthetically refined design. Made in Germany with 100% renewable energy and produced without lead or PFAS, this panel sets the standard for sustainable manufacturing. With a verified 367.6W PTC rating demonstrating real-world performance, the Meyer Burger Black is ideal for residential rooftop installations and architecturally sensitive projects. Rated for 1000V DC systems and backed by an industry-leading 25-year product warranty and 25-year linear performance guarantee.
Heterojunction (HJT) Cell Technology: Advanced HJT cells combine crystalline silicon with amorphous silicon layers for superior efficiency, lower degradation rates, and an exceptional temperature coefficient of -0.259%/K—outperforming conventional PERC and TOPCon technologies in high-heat conditions.
Patented SmartWire Connection Technology (SWCT®): Meyer Burger's proprietary SWCT® replaces traditional busbars with a fine wire mesh, maximizing light capture, reducing resistive losses, and delivering exceptional cell breakage resistance and long-term reliability.
Premium All-Black Aesthetic: Elegant black frame and black backsheet design blends seamlessly with any roofline, making it the ideal choice for homeowners and architects who demand both performance and curb appeal.
PTC Rated Performance: 367.6W PTC rating demonstrates real-world efficiency under actual operating conditions, providing reliable performance expectations for system designers and installers.
Industry-Leading 25/25 Warranty: Backed by a full 25-year product warranty and 25-year linear performance guarantee with only 0.25% annual degradation—among the lowest in the industry—ensuring maximum return on investment over the life of the system.
Made in Germany, Sustainably: Manufactured using 100% renewable energy with no lead or PFAS, meeting the highest standards for environmental responsibility and regional value creation.
This solar panel harnesses sunlight through its advanced Heterojunction (HJT) N-type monocrystalline silicon cells, combining crystalline and amorphous silicon layers to transform solar energy into electricity with exceptional efficiency—even on cloudy or high-temperature days.
Heterojunction Cell Architecture: HJT cells feature ultra-thin amorphous silicon layers on both sides of the crystalline wafer, creating a superior passivation effect that minimizes recombination losses and maximizes energy conversion at all irradiance levels.
Half-Cut Cell Design: 120 half-cut cells reduce internal resistance and power loss, improving shading tolerance and delivering higher energy yields in real-world rooftop conditions with partial shading.
SmartWire Connection Technology (SWCT®): Patented fine wire mesh interconnection maximizes active cell area, improves light absorption, and provides superior mechanical resilience compared to traditional busbar designs.
