HD Solar HD-72HBD-550M 550W Bifacial Polycrystalline Solar Panel
Model HD-72HBD-550M | Bifacial | 144 Cells | Polycrystalline | 1500V System Voltage
Product Overview
The HD Solar HD-72HBD-550M is a high-output bifacial solar panel designed for strong energy generation and dependable long-term performance. This 550W module combines polycrystalline cell technology with a 144-cell layout for efficient power delivery in commercial and utility-scale systems. It offers a power tolerance of 0 to +3%, which helps support stable real-world output. With a module efficiency of 21.5%, it delivers competitive performance for projects that need reliable solar yield. The panel is built for demanding environments and supports a maximum system voltage of 1500V. Its robust structure, anodized aluminium frame, and IP68 junction box add durability for outdoor operation.
Key Benefits
High Power Output: The module delivers 550Wp, making it suitable for projects that require strong energy production.
Bifacial Design: Its bifacial construction can help capture additional light from the rear side in suitable installations.
Efficient Module Performance: The 21.5% efficiency rating supports strong output in a compact footprint.
Durable Construction: Anodized aluminium framing and IP68 protection support reliable outdoor use.
Project-Friendly Electrical Ratings: A 1500V maximum system voltage and 30A fuse rating improve compatibility for larger solar arrays.
How It Works
The HD-72HBD-550M converts sunlight into electricity through polycrystalline solar cells arranged in a 144-cell module format. When sunlight reaches the front surface, the cells generate direct current for immediate use or inverter conversion. The bifacial design can also use reflected light from the rear side, which may improve output in the right mounting conditions. Electrical performance remains stable across varied environments due to its temperature coefficient values and wide operating temperature range. The panel is engineered for system integration, with high-voltage support and standard cabling for practical installation. Its durable construction helps protect internal components during long-term field operation.
Front-Side Solar Capture: The front glass lets sunlight reach the cells, where it is converted into electrical energy. This is the primary generation method in standard operation.
Rear-Side Bifacial Gain: The bifacial structure allows additional light capture from reflective surfaces. This can support higher yield in bright installation environments.
System Integration and Protection: The module works within a 1500V system and includes an IP68 junction box. These features help it fit larger arrays while maintaining strong protection.
