HG Group HGT460-72BB 460W Bifacial PERC Monocrystalline Solar Panel
Model HGT460-72BB | PERC Monocrystalline | 144 Half-Cell | Bifacial | 1500V System Voltage
Product Overview
The HG Group HGT460-72BB bifacial PERC monocrystalline solar panel delivers up to 460 watts of high density power in a robust utility scale format. This advanced module combines high efficiency PERC cells with bifacial generation, so energy is harvested from both the front and rear sides for boosted yields on reflective surfaces. With a panel efficiency up to 21.2 percent, the module is ideal for commercial rooftops, ground mounts, carports, and large off grid systems where space is valuable. Power output is supported by a linear performance warranty, with 96.2 percent retained at year five and 84.95 percent still guaranteed after 30 years. The HGT460-72BB uses 144 monocrystalline half cells, a low profile anodized aluminium frame, and 2.0 millimetre tempered glass to balance strength and weight at only 27 kilograms. Designed for modern 1500 volt system architectures and a 20 amp series fuse rating, this panel integrates easily into high string voltage arrays while maintaining excellent thermal stability and low degradation.
Key Benefits
High power density for limited space: Rated at 460 watts with up to 21.2 percent efficiency, this module extracts more energy from every square metre, helping reduce array footprint and balance of system costs on rooftops or constrained sites.
Bifacial PERC technology for extra yield: The bifacial design captures light from both the front and rear surfaces, delivering additional backside gain on bright or reflective ground conditions and improving lifetime energy production without extra roof area.
Long term performance assurance: A linear power warranty supports 96.2 percent output after five years and 84.95 percent after 30 years, providing strong reassurance for investors, EPC partners, and owners planning long asset lifetimes.
Robust mechanical design: The module features 2.0 millimetre tempered glass, an anodized aluminium frame, and IP68 junction box protection, which together support strong mechanical loads and reliable operation in demanding outdoor environments.
System friendly electrical characteristics: With a maximum system voltage of 1500 volts, 20 amp series fuse rating, and tightly controlled positive power tolerance from zero to plus one percent, the HGT460-72BB integrates neatly into modern string inverters and optimised DC designs.
How It Works
The HGT460-72BB solar panel converts sunlight into clean DC electricity using high efficiency bifacial PERC monocrystalline cells. Each of the 144 half cut cells is designed to absorb direct light on the front surface, while the bifacial structure also collects reflected and diffuse light on the rear. When photons strike the silicon cell, charge carriers are generated and driven by the internal electric field, producing current and voltage at the module terminals. In standard test conditions, the panel reaches a maximum power of 460 watts, with a voltage at maximum power of 41.9 volts and a current at maximum power of 10.99 amps. Under more realistic operating conditions around 45 degrees Celsius nominal temperature, power stabilises near 342 watts. The module connects to compatible inverters through MC4 style connectors and weather sealed junction boxes, allowing energy to flow into grid tied, hybrid, or off grid systems for immediate use or storage.
Bifacial energy capture: The front side of the panel faces the sun and delivers the primary output, while the rear side collects additional light reflected from surfaces such as light concrete, gravel, or snow. This rear gain can significantly boost annual energy yield without adding extra modules, especially in open rack ground mount configurations with high albedo surroundings.
PERC monocrystalline cell operation: Passivated emitter and rear cell technology increases internal light trapping and reduces recombination losses inside each cell. As a result, more of the incoming sunlight is converted into usable electrical energy, improving module efficiency and performance in low light conditions such as early morning, late afternoon, or cloudy weather.
Thermal and electrical stability: The module is engineered to operate reliably between minus 40 and plus 85 degrees Celsius, with a Pmax temperature coefficient of minus 0.35 percent per degree Celsius. This controlled coefficient limits power loss on hot days, while the 1500 volt system rating allows long strings that minimise cable runs and DC losses throughout the array.
