Model MQ Energy 285 | Polycrystalline | 120 Half-Cell Polycrystalline | Monofacial | 1500V System Voltage
The Taizhou MQ Energy MQ Energy 285 285W Polycrystalline 120-Cell Solar Panel is designed to deliver reliable power for residential, commercial, and small industrial projects. This polycrystalline module offers a rated maximum power of 285 Wp with a positive power tolerance from 0 to +2 percent. Stable performance is supported by a panel efficiency of up to 17.05 percent under standard test conditions. With a wide operating temperature range from -40 to 85 degrees Celsius, it is suitable for challenging climates and demanding environments. The robust anodized aluminium frame and 3.2 mm tempered glass provide strong mechanical protection against wind, snow, and impact. A 12-year product warranty backs long term durability and dependable output in the field. The panel is manufactured in China by Taizhou MQ Energy Technology Co., Ltd., supporting global solar projects with consistent quality. Compact dimensions of 1685 x 992 x 35 mm and a weight of 18.5 kg make handling and installation straightforward for rooftop and ground mounted arrays. This module is a practical choice for users seeking a balance of efficiency, affordability, and proven polycrystalline technology. The MQ Energy 285 series covers a power range from 285 to 295 Wp, giving designers flexibility when sizing system capacity.
Reliable 285–295 Wp output range: The module offers a nominal 285 Wp rating with a series power range up to 295 Wp, helping system designers fine tune array sizing while maintaining stable performance and predictable yields.
High efficiency polycrystalline design: Module efficiency between 17.05 and 17.65 percent allows more power from limited roof or ground space, helping maximize kilowatt hour production without increasing installation footprint.
Durable construction for harsh climates: An anodized aluminium frame, 3.2 mm tempered glass, and EVA encapsulation protect cells from moisture, dust, and mechanical stress, supporting long service life in a wide range of weather conditions.
Stable performance across temperatures: Low temperature coefficients for power, voltage, and current help maintain output as module temperature rises, improving real world energy production during hot and sunny days.
Easy integration into modern systems: A maximum system voltage of 1500 V, MC4 compatible connectors, and 4 mm² cables support simple string design, fast installation, and compatibility with a wide range of contemporary inverters and mounting systems.
This polycrystalline solar panel converts sunlight into usable electrical energy through its 120 interconnected solar cells. Each cell is made from polycrystalline silicon, which absorbs incoming photons and releases electrons when exposed to light. The internal wiring of the module collects this movement of electrons and forms a direct current power output at the module terminals. Under standard test conditions, the MQ Energy 285 panel delivers up to 285 Wp at a voltage of 31.4 V and a current of 9.08 A. The open circuit voltage of 38.6 V and short circuit current of 9.48 A indicate the maximum electrical potential and current available from the module. When panels are connected together in strings and paired with an inverter, the direct current is converted into alternating current. This alternating current can then supply on site loads or feed into the grid, depending on system configuration and local regulations. The panel’s design, including tempered glass, EVA encapsulation, and sealed junction box, works together to protect the cells and maintain performance over many years of outdoor operation. Temperature coefficients ensure that changes in operating temperature are accounted for, helping to predict energy generation more accurately throughout the year. Overall, the module plays a central role in any PV system by capturing solar energy and turning it into dependable electrical power.
Photon capture and DC generation: Polycrystalline silicon cells absorb sunlight and create a flow of electrons, which is collected as direct current at the module’s output leads. The 120 cell layout optimizes the active area, improving the module’s ability to convert incident irradiation into usable power.
Operating point at maximum power: Under rated conditions, the panel operates near its maximum power point at 31.4 V and 9.08 A, where energy harvest is most efficient. Modern inverters track this point continuously, ensuring the array extracts as much power as possible as sunlight and temperature vary.
System integration and safety: With a maximum system voltage of 1500 V and a series fuse rating of 15 A, the module can be safely combined in longer strings within modern high voltage arrays. MC4 connectors, IP68 junction box protection, and UV resistant 4 mm² cables provide secure electrical connections and help maintain safety and reliability over time.
