Couleenergy CLM-120M 120W Flexible Monocrystalline Solar Panel
Model CLM-120M | PERC Flexible | Monocrystalline | Flexible | 600V System Voltage
Product Overview
The Couleenergy CLM-120M is a flexible monocrystalline solar panel designed for dependable performance and easy installation. It uses shingled PERC cell technology to improve output while reducing optical and resistive losses. The lightweight 1.7 kg structure supports curved surfaces and mobile applications. With a 120 Wp output, it suits compact off-grid projects, marine use, vehicles, and outdoor power systems. The ETFE front layer and IP68 junction box help support durability in demanding environments. A 5-year workmanship and materials warranty adds confidence for long-term use.
Key Benefits
Flexible Installation: The panel bends to fit curved surfaces with a bending range of at least 30 degrees.
Shingled PERC Efficiency: Shingled cell construction helps reduce losses and improve power delivery in a compact format.
Weather Resistance: The module is built for harsh conditions and is almost impervious to corrosion.
Lightweight Design: At only 1.7 kg, the panel is easier to transport, handle, and mount.
Reliable Output: A positive power tolerance of 0 to +3% supports stable performance expectations.
OEM and ODM Support: The product supports customized sourcing needs for commercial and project-based applications.
How It Works
This flexible solar module converts sunlight into usable electricity through monocrystalline PERC cells arranged in a shingled layout. The shingled design reduces resistance and minimizes space loss. That helps the panel produce stable output in a slim and lightweight format. The flexible construction supports installation on surfaces that cannot accept rigid modules. Its ETFE encapsulant helps protect the cells while maintaining good light transmission. The IP68 junction box and MC4 connector improve connection reliability outdoors. Together, these features make the module practical for curved, mobile, and weather-exposed applications.
Shingled Cell Layout: Cells are arranged to reduce optical and resistive losses. This improves the flow of current through the module and supports better energy harvest.
Flexible Module Body: The panel can bend to suit curved surfaces. This expands installation options for boats, vehicles, and uneven rooftops.
Protected Electrical Connections: The IP68 junction box and MC4 connector help protect the system from harsh outdoor conditions. The cable setup supports secure and practical wiring during installation.
