Model CEC6-72-555TDHV | N-Type TOPCon | 144 Half-Cell 182×91 mm | Bifacial | 1500V System Voltage
The CECEP Solar CEC6-72-555TDHV N-type TOPCon bifacial module delivers up to 555 watts of high efficiency power in a robust 144 half-cell design. This premium monocrystalline solar panel is engineered for commercial, utility scale and large residential projects seeking maximum output per square meter. Advanced N-type TOPCon cells provide excellent low light performance and reduced degradation, helping systems maintain stronger energy yields over decades of operation. The bifacial construction allows power generation from both the front and rear surfaces when mounted over reflective ground or roofing. With a module efficiency up to 21.5 percent, a maximum system voltage of 1500 volts and strong mechanical load ratings, this panel offers a reliable platform for high performance arrays. Installers can use it confidently in demanding climates while owners benefit from a long linear power warranty and low levelized cost of energy.
High power density for limited roof space: With a rated output of 555 watts and efficiency up to 21.5 percent, this module produces more energy from the same footprint. Projects with constrained roof or ground area can reach their target capacity using fewer panels and mounting points.
Bifacial generation boosts total energy yield: The bifacial glass construction captures sunlight from the front and reflected light at the rear side. When installed above bright surfaces such as light gravel, white membrane or concrete, additional rear side output can significantly increase annual energy production.
Durable design for harsh environments: The tempered glass and robust frame are certified to withstand wind loads up to 2400 Pascal and snow loads up to 5400 Pascal. An IP68 junction box and quality encapsulation help protect critical components against moisture and dust ingress in demanding sites.
Improved long term reliability and low degradation: N-type cell technology and a controlled total degradation rate of about 0.42 percent per year support stable output over time. Power is warranted to remain at least 94.6 percent after 12 years and at least 87.4 percent after 30 years of operation.
Flexible system integration for modern arrays: With 1500 volt system capability, a 25 amp series fuse rating and 250 millimeter leads, this module suits string inverters and central inverter architectures. Installers can design longer strings to reduce balance of system costs and simplify layout on large rooftops or ground mounts.
The CECEP Solar CEC6-72-555TDHV panel converts sunlight into usable electrical energy through advanced N-type TOPCon monocrystalline cells arranged in a 144 half-cell layout. Each cell absorbs photons through the front glass, releasing electrons that flow as direct current across the circuit. The bifacial structure allows the rear side to capture reflected light, further increasing current and power output when conditions are favorable. Electrical energy flows through busbars to the IP68 junction box, then exits via the factory fitted cables to string wiring and inverters. Under standard test conditions, the module operates at a maximum power voltage of about 42.2 volts and current of about 13.16 amps, producing approximately 555 watts. Temperature coefficients help predict real world performance at varying temperatures so designers can accurately model system yield.
Front and rear side light capture: The tempered front glass allows high transmission of direct and diffuse sunlight onto the N-type cells. At the same time, the bifacial design exposes the rear surface to reflected light from the ground or neighboring structures. When the module is elevated above bright surfaces, the rear side can generate additional current, raising overall energy yield without increasing array footprint.
N-type TOPCon cell operation and efficiency: TOPCon technology uses a passivated contact structure that reduces recombination losses inside each cell. This approach allows a higher portion of absorbed photons to be converted into electrical current rather than wasted as heat. N-type wafers also demonstrate better resistance to light induced degradation, helping the module sustain close to its initial performance over the full warranty period.
Integration with inverters and electrical systems: Current and voltage from each module combine in series strings that feed a DC input on a compatible inverter. The 1500 volt system rating enables long strings, which can lower cable runs and combiner hardware in large installations. The inverter converts the direct current into grid ready alternating current, while monitoring operates within safe voltage, current and temperature limits defined by the module specifications.
