The FMCS-440M is a cutting-edge 440W MCS-certified semi-flexible monocrystalline solar panel that redefines efficiency and adaptability. Built with 182mm silicon wafers, PERC technology, and half-cut cells, this panel maximises power output while reducing energy losses. Its innovative design ensures exceptional durability, lightweight construction, and superior performance, even in challenging conditions. Perfect for curved rooftops, weak load-bearing surfaces, and corrugated metal roofs, the FMCS-440M is the ideal solution for residential, commercial, and industrial solar applications.

Advanced energy efficiency

With an advanced combination of PERC and half-cut cell technology, the FMCS-440M achieves superior energy conversion efficiency, ensuring maximum power output from every module. By minimising adaptive losses, this panel optimises energy generation, making it a high-performance choice for solar installations in various environments.

Exceptional power-to-weight ratio & versatile installation

Designed for ease of installation and adaptability, the FMCS-440M is exceptionally lightweight at just 4.1kg per unit area, making it 70% lighter than conventional solar panels. Despite its ultra-lightweight construction, it delivers an impressive 200W per square meter of installation area, making it ideal for surfaces with low load-bearing capacity, such as corrugated metal roofs, coal sheds, and curved rooftops.

Enhanced performance in shaded conditions with integrated junction box diodes

The FMCS-440M 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 for durability. It has undergone rigorous weather testing and is built to withstand harsh environmental conditions. The panel is resistant to sand, dust, acid, alkali, and salt mist corrosion, making it suitable for installations in extreme climates. Additionally, its anti-PID (Potential Induced Degradation) and hail shock resistance further enhance its longevity and reliability.

Long-term reliability & warranty protection

For long-term peace of mind, the FMCS-440M 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.

The FMCS-440M semi-flexible solar panel is the perfect combination of innovation and efficiency, offering superior performance in any environment. Whether for residential, commercial, or industrial applications, this high-efficiency panel provides a reliable, sustainable energy solution for years to come.

The panel is fitted with 0.3m of 4.0mm² solar cable which can work at high roof temperatures, with minimum power losses. A pair of male / female MC4 connectors are crimped on the end of cable for easy connection to other solar panels, your existing system or 4.0mm² extension cable. The MC4 connectors can also be cut off when wiring to the screw terminals of a solar charge controller.
