MQ Energy MQ Energy 390 390W PERC Monocrystalline Solar Panel
Model MQ Energy 390 | PERC Monocrystalline | 144 Half-Cell | Monofacial | 1000V System Voltage
Product Overview
The MQ Energy 390 390W PERC monocrystalline solar panel is engineered for dependable power and long term performance. This high efficiency module delivers a maximum output of 390 Wp, making it ideal for home, commercial, or off grid systems. Its advanced PERC cell design and 144 half cut monocrystalline cells help capture more sunlight in the same roof area. With a module efficiency of up to 19.66 percent, energy production is optimized even in limited space. A robust anodized aluminium frame and tempered glass provide strong mechanical protection against harsh outdoor conditions. The panel is designed to operate reliably between minus 40 and plus 85 degrees Celsius. A 12 year product warranty supports long term investment security for installers and system owners. Manufactured by Taizhou MQ Energy Technology Co., Ltd. in China, this module suits projects that demand good efficiency and competitive cost. The MQ Energy 390 panel integrates easily into most 1000V DC systems using standard MC4 compatible connectors. It offers a balanced combination of power, durability, and ease of installation for a wide range of solar applications.
Key Benefits
High power density for limited roof space: The 390 Wp output and up to 19.91 percent efficiency allow strong energy production from a compact footprint. This helps maximize yield on residential roofs and small commercial structures.
Reliable PERC monocrystalline technology: PERC cell architecture improves light absorption and reduces recombination losses. This design supports stable performance across a wide range of operating temperatures.
Durable construction for long service life: Tempered 3.2 mm glass and an anodized aluminium frame protect cells from mechanical stress. IP67 junction box protection helps keep moisture and dust away from electrical connections.
Better energy yield in real conditions: A low negative temperature coefficient of power, at minus 0.4 percent per degree Celsius, limits losses on hot days. Optimized current and voltage ratings make the panel suitable for many inverter inputs.
Easy integration and installation: Standard MC4 connectors and 4 square millimetre cables simplify wiring in series strings. The 2000 by 992 millimetre size and 22.5 kilogram weight support straightforward handling on site.
How It Works
This solar panel converts sunlight into clean direct current electricity using high quality monocrystalline PERC cells. When photons strike the silicon cells, electrons are released and driven by the internal electric field. The resulting current flows through the interconnected 144 half cut cells and exits through the junction box. Your inverter then converts the direct current to alternating current suitable for household or commercial loads. The MQ Energy 390 panel is designed to operate efficiently across its rated temperature range, from minus 40 to plus 85 degrees Celsius. Power tolerance from zero to plus one percent helps ensure that real world output meets or slightly exceeds the nameplate rating. A maximum system voltage of 1000 volts allows compatibility with many residential and commercial string inverter designs. The module is built so that energy harvest remains stable during daily and seasonal temperature swings.
PERC monocrystalline cell operation: Each 156 by 78 millimetre PERC cell features a passivated rear surface that reflects unabsorbed light back into the silicon. This design increases the chance of photon absorption and improves conversion efficiency compared with standard cells.
Half cut cell and string layout: The 144 half cut cells are interconnected in strings to reduce resistive losses and improve shade tolerance. Lower current in each cell strip also reduces heat build up, supporting better performance under high irradiance.
Power flow, protection, and system integration: Generated current is collected through 4 square millimetre cables connected via MC4 type connectors. The IP67 rated junction box helps keep connections dry and protected, allowing the panel to function reliably in outdoor environments.
