Model CEC6-72-425PH/PHV | Polycrystalline Silicon | 144 Half-Cell Poly Cells | Monofacial | 1500V System Voltage
The CECEP Solar CEC6-72-425PH/PHV polycrystalline solar panel delivers dependable 425 Wp output for commercial and residential arrays. This high quality module combines durable construction, strong warranties and efficient power conversion for long term energy savings. With module efficiency up to 19.55 percent, more energy can be generated from limited roof or ground space. The panel uses 144 half cut polycrystalline cells to reduce resistive losses and improve real world performance. It is designed for system voltages up to 1500 volts, supporting modern string inverters and large scale systems. A robust IP68 junction box and tempered glass enhance protection against dust, moisture and harsh weather. The wide operating temperature range from minus 40 to 85 degrees Celsius suits varied climates and demanding sites. This module offers an attractive balance between cost, reliability and power density for many project types. Power warranties up to 25 years support long term yield and predictable project returns. The CEC6-72-425PH/PHV sits at the top of its series with a power range from 405 to 425 watts peak. Installers can specify this panel to maximise output while maintaining a proven polycrystalline technology platform.
High power density in a standard footprint: Rated at 425 Wp with efficiency up to 19.55 percent, this module delivers strong output from a conventional 72 cell format, helping projects achieve higher system capacities without extra array area.
Robust long term performance: A low annual degradation rate of around 0.77 percent supports 89.8 percent power after 12 years and 80.7 percent after 25 years, improving lifetime energy yield and financial returns for asset owners.
Durable construction for harsh environments: The panel uses 3.2 millimetre tempered low iron glass, an IP68 junction box and a wide operating temperature range from minus 40 to 85 degrees Celsius, supporting installation in challenging climates and industrial sites.
Flexible system design: With a maximum system voltage of 1500 volts and a 20 amp series fuse rating, the module integrates readily with modern string inverters, long strings and utility scale designs while keeping balance of system costs under control.
Proven polycrystalline technology from a trusted brand: Manufactured by CECEP Solar Technology in China, the panel leverages established polycrystalline cell technology and strict quality control, offering reliable performance for commercial, industrial and residential projects.
Lightweight yet strong module frame: At approximately 24 kilograms with dimensions of 2094 by 1038 by 30 millimetres, the module balances manageable handling for installers with structural strength suitable for wind and snow load requirements.
This CECEP Solar CEC6-72-425PH/PHV panel converts sunlight into usable direct current electricity through 144 half cut polycrystalline cells. Each cell is made from silicon that releases electrons when hit by photons, creating an electric current. The half cell layout reduces resistive losses and improves shade tolerance across the module area. Electrical connections route the combined current to the integrated junction box, which protects terminations against dust and moisture. From there, cabling carries the direct current to an inverter, where it is converted into alternating current suitable for homes, businesses or grid export. The panel operates efficiently across a range of conditions, with performance defined at 25 degrees Celsius, 1000 watts per square meter and air mass 1.5. Temperature coefficients describe how output changes as the module heats or cools, helping designers model energy yield accurately. The stable mechanical frame supports safe mounting on roof, ground or commercial structures using industry standard racking hardware.
Photovoltaic energy conversion: Polycrystalline silicon cells absorb solar radiation and free electrons inside the crystal structure, generating a direct current flow across each cell. The cells connect electrically in series and parallel strings to reach a maximum power voltage of about 39.76 volts and a current of around 10.69 amps under standard test conditions.
Module behaviour in real weather: As temperatures rise above the nominal 42 degrees Celsius operating level, the negative temperature coefficient of Pmax, at about minus 0.36 percent per degree, slightly reduces power output. The voltage also falls with temperature through a Voc coefficient of minus 0.28 percent per degree, while the current gently increases due to a positive Isc coefficient of 0.05 percent per degree.
System integration and protection: The 1500 volt maximum system voltage rating allows longer strings and fewer home runs back to the inverter, lowering cabling and labour costs for installers. An IP68 junction box and appropriate series fuse rating of 20 amps support safe system design, while standard connectors and cable lengths simplify integration into rooftop and ground mount arrays.
