HD Solar HD-72HBD-545M 545W Bifacial Polycrystalline Solar Panel
Model HD-72HBD-545M | Polycrystalline | 144 Cells | Bifacial | 1500V System Voltage
Product Overview
The HD Solar HD-72HBD-545M is a high-output bifacial solar panel built for strong commercial and utility-scale performance. It delivers 545 Wp of rated power with a 21.3% module efficiency. Its 144-cell layout supports stable energy generation across demanding environments. The bifacial design helps capture reflected light from the rear side. That can improve total energy yield in suitable installations. With a 1500V maximum system voltage, it supports modern, efficient string designs. The robust anodized aluminium frame and IP68 junction box add durability. This panel is designed for reliable long-term operation in challenging climates.
Key Benefits
High Power Output: The module delivers 545 Wp for strong system performance and fewer panels per installation.
Bifacial Energy Gain: Rear-side light capture can increase production where ground reflection is available.
High Efficiency: The 21.3% efficiency rating supports better space utilization and stronger energy density.
Durable Construction: Anodized aluminium framing, tempered glass, and IP68 protection improve outdoor resilience.
System Friendly Design: The 1500V system rating and 30A fuse rating support efficient design flexibility.
How It Works
This solar panel converts sunlight into electricity through 144 interconnected cells. Each cell produces direct current when exposed to solar radiation. The bifacial structure allows the rear side to use reflected light for additional output. That makes the panel especially effective on bright surfaces and optimized ground mounts. Power is then routed through the junction box and bypass diodes. These components help reduce losses during partial shading. The module’s temperature characteristics support stable operation in hot and cold conditions. Its high voltage design also helps reduce current losses in larger solar arrays.
Photon Conversion: Sunlight strikes the polycrystalline cells and generates electrical current. The module then converts that current into usable DC power for the system.
Bifacial Capture: The rear surface can absorb reflected light from the installation area. This can improve total output when the mounting environment supports rear-side illumination.
Protection and Flow Control: Bypass diodes and the IP68 junction box support safer current flow. They also help maintain performance when shading or environmental stress appears.
