Model CWT575-108TNB12 | N-Type TOPCon | 108 Half-Cell Monocrystalline | Bifacial | 1500V System Voltage
The CW Enerji CWT575-108TNB12 N-Type TOPCon bifacial monocrystalline solar panel delivers high efficiency power for modern residential and commercial arrays. With a maximum output of 575 Wp and module efficiency up to 22.46%, this advanced panel helps reduce balance of system costs and maximize energy yield per square meter. N-type TOPCon cell technology supports strong performance in real world conditions and helps limit light induced degradation over the lifetime of the system. The bifacial design can harvest additional energy from reflected light on the rear side, increasing kWh production on suitable mounting surfaces. Durable double glass construction and an IP68 junction box support long term reliability in challenging environments. Engineered in Turkey by CW Enerji Mühendislik Ticaret ve Sanayi A.Ş, this panel offers a smart balance of performance, longevity and value. It suits grid tied projects that demand dependable output, strong warranties and bankable technology.
High power density: A 575 Wp rating and efficiency up to 22.46% allow more power from fewer panels, freeing roof or ground space and helping reduce mounting hardware and labor costs on high demand projects.
N-Type TOPCon reliability: N-type TOPCon cells limit light induced degradation and support strong long term performance, making the panel suitable for systems where consistent output and predictable returns are critical for investors and owners.
Bifacial energy gain: The bifacial double glass design enables rear side generation from reflected light, which can deliver additional kWh yield on bright surfaces such as white roofs, concrete pads or high albedo ground covers.
Robust mechanical strength: The module is tested for wind loads up to 2400 Pa and snow loads up to 5400 Pa, supporting reliable operation in harsh climates with heavy winds, snow accumulation or demanding mounting conditions.
Bankable warranty structure: A 12 year product warranty and 30 year linear performance warranty with only 0.42% annual degradation support long horizon projects, giving owners confidence in lifetime energy production and revenue forecasts.
This CW Enerji CWT575-108TNB12 solar panel converts sunlight into usable electricity through high efficiency N-type TOPCon monocrystalline cells. When the panel is exposed to solar irradiance, photons strike the silicon cells and free electrons, generating direct current at the module output leads. The front side produces most of the power, while the bifacial rear side harvests additional energy from light reflected off nearby surfaces. The generated direct current flows through the IP68 junction box and factory fitted cables toward a compatible inverter, which converts it to alternating current for on site consumption or grid export. Integrated anti reflection, self cleaning glass helps maintain light transmission across the surface, while the robust double glass laminate protects internal cells from moisture, mechanical stress and temperature cycling. Together, these features allow the module to deliver reliable power across a wide operating temperature range from -40°C to +85°C in varied climates.
N-Type TOPCon cell operation: Each 210×105 mm N-type TOPCon cell uses advanced passivated contacts to reduce electron recombination. This design helps capture more of the incoming light as electrical energy, particularly in high irradiance and high temperature conditions.
Bifacial double glass generation: The panel uses glass on both sides so the rear surface can receive reflected or diffuse light. When mounted over bright ground or reflective membranes, this rear side contributes extra current and boosts total output beyond the front power rating.
System integration and safety: The module connects into strings up to 1500 V DC, which reduces string count on larger arrays and simplifies wiring. The IP68 junction box and factory crimped leads support secure electrical connections, while compliance with IEC safety standards helps ensure safe operation within certified systems.
