HD Solar HD-72HBD-535M 535W Bifacial Polycrystalline Solar Panel
Model HD-72HBD-535M | Polycrystalline | 144 Cells | Bifacial | 1500V System Voltage
Product Overview
The HD Solar HD-72HBD-535M is a high-output bifacial solar panel built for dependable energy generation. It combines a 535 Wp rating with strong module efficiency and a durable 144-cell design. The panel is designed for stable performance in utility-scale and commercial installations. Its polycrystalline construction supports cost-conscious project planning. The bifacial format helps capture additional light from the rear side. This makes the module a practical choice for sites with reflective ground conditions. A rugged frame and IP68 junction box support long service life. The design also suits demanding environments with wide temperature variation.
Key Benefits
High Power Output: The module delivers 535 Wp for strong energy yield in larger systems.
Bifacial Design: Rear-side light capture can improve overall generation in suitable installations.
Efficient Space Use: 20.9% efficiency helps maximize power production within limited roof or ground area.
Robust Construction: Anodized aluminium framing and 2 mm glass improve durability and handling strength.
System Flexibility: A 1500 V maximum system voltage supports modern commercial and utility solar designs.
How It Works
This solar panel converts sunlight into usable direct current electricity through photovoltaic cells. The 144-cell configuration is arranged for balanced voltage and current delivery. Front-side light is absorbed by the cells during normal operation. Rear-side illumination can also contribute to output because the module is bifacial. That extra gain depends on mounting height, surface reflectivity, and site conditions. The panel is built for stable operation across a wide temperature range. Electrical protection and durable materials help support long-term field performance. It is engineered for projects that need reliable output and efficient system integration.
Photovoltaic Conversion: Sunlight strikes the polycrystalline cells and generates electrical current. This current is then routed through the module terminals for system use.
Bifacial Energy Capture: Light reaching the rear side can be converted into additional electricity. The actual benefit depends on installation geometry and ground conditions.
Temperature Management: The module is rated for operation from -40 to 85 °C. Temperature coefficients describe how output changes as cell temperature rises.
