Model CWT570-108TNB12 | N-Type TOPCon | 108 Half-Cell Monocrystalline | Bifacial | 1500V System Voltage
The CW Enerji CWT570-108TNB12 570W N-Type TOPCon bifacial solar panel delivers high power density for commercial and residential rooftops. This advanced monocrystalline module uses N-type TOPCon cells to achieve up to 22.26% panel efficiency with a compact footprint. Its bifacial design allows energy to be harvested from both the front and rear sides, increasing yield on reflective surfaces and in high-albedo environments. Engineered for long-term reliability, the panel carries a 12-year product warranty and a 30-year linear power warranty with low annual degradation. Self-cleaning, anti-reflection glass improves light capture and reduces maintenance needs over the system lifetime. The module is built to withstand wind loads up to 2400 Pa and snow loads up to 5400 Pa, making it suitable for challenging climates. With a maximum system voltage of 1500 V and a 35 A series fuse rating, the CWT570-108TNB12 integrates efficiently into modern high-voltage solar arrays. This panel is designed and manufactured by CW Enerji in Turkey, providing a dependable solution for projects seeking high output, durability, and long-term performance.
High power density in a compact footprint: With a maximum power output of 570 Wp and 22.26% efficiency, this module delivers more energy per square meter, enabling powerful systems even on constrained rooftop or ground-mount areas.
Bifacial TOPCon technology for higher yield: Bifacial N-type TOPCon cells capture light from both sides of the panel, enhancing energy production on reflective surfaces and improving overall system performance through the year.
Reliable long-term performance: A 12-year product warranty and a 30-year linear performance warranty support stable output, with 93.4% power guaranteed at year 12 and 87.4% at year 30 for long-term returns.
Robust build for demanding environments: The panel withstands wind loads up to 2400 Pa and snow loads up to 5400 Pa, while IP68 junction boxes and durable encapsulation support reliable operation in harsh outdoor conditions.
Optimized glass and low-light performance: Anti-reflection, self-cleaning glass reduces dust buildup and enhances light transmission, and the module maintains strong performance under low irradiation for more consistent daily energy yield.
The CW Enerji CWT570-108TNB12 converts sunlight into usable electrical energy through advanced N-type TOPCon bifacial cell technology. When sunlight hits the monocrystalline cells on the front side, photons are absorbed and released as electrical current, which flows through a network of 18-busbar cell interconnections. The bifacial construction also allows the rear side of the module to capture reflected and diffuse light, increasing overall yield compared with standard monofacial panels. Self-cleaning, anti-reflection glass improves light transmission by minimizing soiling and surface reflection losses. The resulting direct current power is delivered safely through the IP68-rated junction box and cables to the string inverter or hybrid inverter in the system. Once connected into a 1500 V DC array, multiple modules operate together to reach the desired system voltage and power level for residential, commercial, or industrial installations. The low degradation rate and stable temperature coefficients help maintain efficient operation over decades, even in regions with high temperature swings or challenging climates.
N-Type TOPCon cell architecture: N-type TOPCon cells use a passivated contact structure that reduces recombination losses and improves carrier lifetime. This design supports higher efficiency and slower degradation compared with many P-type cell technologies in real-world conditions.
Bifacial energy harvesting: The bifacial module generates power from front and rear surfaces, using reflected light from the ground or mounting surface. This rear-side gain can significantly increase energy yield per module when paired with light-colored roofs, ballast systems, or elevated trackers.
High-voltage system integration: With a maximum system voltage rating of 1500 V DC and a 35 A series fuse rating, the panel integrates into modern high-voltage string designs. This configuration can reduce balance-of-system costs by allowing longer strings and fewer parallel connections.
