The FMCSB-250M is a state-of-the-art 250W MCS-certified semi-flexible monocrystalline solar panel that combines high performance with a sleek, all-black aesthetic. Engineered with 182mm silicon wafers, PERC technology, and half-cut cells, this panel delivers exceptional power output while minimising energy losses. Designed for curved rooftops, weak load-bearing surfaces, and corrugated metal roofs, the FMCSB-250M is ideal for residential, commercial, and industrial solar applications where both efficiency and aesthetics matter.

Advanced energy efficiency

Utilising PERC and half-cut cell technology, the FMCSB-250M achieves superior energy conversion efficiency, ensuring maximum power generation in a compact and lightweight form. By reducing adaptive losses, it optimises energy output, making it a high-performance choice for installations in diverse environments.

Ultra-lightweight & versatile installation

Weighing just 4.1kg per unit area, the FMCSB-250M is 70% lighter than conventional solar panels, significantly reducing structural load. Despite its lightweight build, it delivers 190W per square meter of installation area, making it perfect for corrugated metal roofs, coal sheds, and curved rooftops. Its semi-flexible design allows for seamless integration on surfaces where rigid panels are impractical.

Enhanced performance in shaded conditions with integrated junction box diodes

The FMCSB-250M features a junction box equipped with three bypass diodes, ensuring optimal performance and reliability in various conditions. The integrated diodes mitigate the risk of hot spots caused by shaded or damaged cells, protecting the panel from potential long-term damage. By allowing the panel to continue generating electricity efficiently, even when partially shaded, the diodes enhance total energy production. In scenarios where only a portion of the panel is shaded, the bypass diodes help maintain consistent power flow, preventing significant energy loss. By reducing thermal stress and preventing excessive heat build-up, the diodes contribute to extending the overall durability and lifespan of the panel. When connected in series, the bypass diodes ensure that shading on one panel does not significantly impact the performance of the entire solar array.

Built for extreme durability

MCS certification guarantees that this solar panel is designed to withstand harsh environments, the FMCSB-250M has passed rigorous weather testing and is resistant to sand, dust, acid, alkali, and salt mist corrosion. Its anti-PID (Potential Induced Degradation) and hail shock resistance ensure long-lasting performance, making it a reliable choice for challenging outdoor conditions.

All-black aesthetic

Featuring an all-black aesthetic, the FMCSB-250M achieves a seamless, high-tech appearance with near-zero colour variation. Every component, from the cells to the backsheet, is meticulously designed for uniformity and deep black consistency. Whether viewed from different angles or under varying lighting conditions, the FMCSB-250M maintains a cohesive black tone, ensuring a sophisticated and modern look. This design harmonises with contemporary architecture, delivering a true all-black solar roof that enhances both function and form.

Long-term reliability & warranty protection

For long-term peace of mind, the FMCSB-250M comes with a 5-year quality and performance guarantee for vehicle/boat installations and 10-year for roof installations, along with a 25-year linear power output warranty, ensuring reliable and efficient energy generation for decades.

Combining high efficiency, extreme durability, and an elegant all-black aesthetic, the FMCSB-250M semi-flexible solar panel is the perfect solution for those who want cutting-edge solar technology without compromising on design. Whether for residential, commercial, or industrial applications, this panel delivers next-level performance with a visually stunning appearance.
