Model CWT655-132PMB12 | PERC Monocrystalline | 132 Half-Cell 210×105 mm | Bifacial | 1500V System Voltage
The CW Enerji CWT655-132PMB12 bifacial PERC monocrystalline solar panel delivers high efficiency and dependable performance for utility, commercial, and large roof projects. With a maximum power output of 655 Wp and module efficiency up to 21.09%, this module helps reduce balance of system costs while maximizing energy yield per square meter. The advanced bifacial design allows energy capture from both the front and rear sides, increasing total power generation on reflective surfaces such as white roofs, concrete, or light gravel. A robust aluminum frame, IP68 junction box, and certified resistance to wind and snow loads support durable operation in challenging climates. This 132-cell module is engineered for 1500 V systems, enabling longer strings and lower BOS costs. Designed and manufactured in Turkey by CW Enerji Mühendislik Ticaret ve Sanayi A.Ş, it combines high conversion efficiency, self‑cleaning glass, and long-term performance warranties, making it a strong choice for bankable solar installations where output, reliability, and lifetime value matter.
High power density for large-scale projects: A 655 Wp output and 21.09% efficiency allow more installed capacity on the same footprint, which helps optimize limited roof or ground space and can reduce overall project cost per watt.
Bifacial energy gain: Rear-side generation captures reflected light from bright surfaces, increasing total kWh production over the system lifetime and improving project returns without extra module area.
Reliable long-term performance: A linear performance warranty with 90% power at 12 years and 83.5% at 30 years supports predictable energy yield projections and enhances investor confidence in long-term cash flows.
Enhanced durability and weather resistance: The IP68 junction box, anti‑reflection glass, and certified wind and snow load ratings are designed to withstand harsh outdoor conditions and reduce maintenance interventions over time.
Optimized for modern 1500 V systems: Compatibility with 1500 V system voltage and a 30 A series fuse rating enables flexible string design, improved efficiency of inverters, and lower cabling and installation costs on larger arrays.
This high-efficiency solar panel converts sunlight into usable DC electricity through its 132 monocrystalline PERC cells arranged in a 6×22 layout. Incoming light hits the textured cell surface and anti‑reflection glass, where it is absorbed and converted into electrical energy through the photovoltaic effect. Because this module is bifacial, light striking the rear side is also harvested, which boosts overall energy yield, especially when mounted over reflective surfaces or on elevated racking. The panel operates within a wide temperature range from -40°C to +85°C, and its carefully engineered temperature coefficients help maintain stable output under real‑world conditions. When connected in strings to a compatible inverter, the generated DC power is converted into AC electricity that can be used on site or exported to the grid. The linear performance warranty and low annual degradation rate support a consistent energy profile over decades, allowing system designers to model long-term production with confidence.
PERC monocrystalline cell architecture: Passivated emitter and rear cell technology increases light capture and reduces electron recombination losses, which improves conversion efficiency compared to standard cells. The monocrystalline silicon structure supports higher performance and delivers a strong power temperature profile in varying climates.
Bifacial energy harvesting: The module is designed to absorb light from both front and rear sides, using the rear glass and cell layout to pick up diffuse and reflected radiation. This design can increase real-world output beyond the nameplate rating when installed over bright surfaces or on elevated mounting systems.
Self-cleaning, anti-reflection glass and robust construction: The coated glass helps minimize dust accumulation and reflection losses, which sustains strong performance between cleaning cycles. Combined with the IP68 junction box, sturdy frame, and high mechanical load ratings, the panel is engineered to operate safely in demanding environments for many years.
