Model HD-66HPH-415M | Polycrystalline | 132 Half-Cell Polycrystalline | Monofacial | 1500V System Voltage
The HD Solar HD-66HPH-415M solar panel delivers reliable 415 Wp output with efficient polycrystalline technology. This versatile module suits residential, commercial, and light industrial rooftop systems that demand dependable performance. Its power range from 405 Wp to 425 Wp allows flexible system design for different array sizes and layouts. High panel efficiency, reaching up to 21.3 percent, helps more energy be harvested from limited roof space. The module uses 132 half-cut polycrystalline cells to reduce resistive losses and improve shade tolerance. A robust anodized aluminium frame and tempered glass front offer strong mechanical strength in harsh environments. The HD Solar HD-66HPH-415M solar panel is produced by Jiangsu Hongde Technology Development Co., Ltd. in China. It is an ideal choice where long term stability, solid power tolerance, and proven crystalline technology are required. Careful thermal design and rated operating temperatures support consistent energy yield over many years. Installers can integrate this module into 1500 V systems with confidence in both safety and performance.
High and flexible power range: The module offers a rated output of 415 Wp, with a series power range from 405 Wp to 425 Wp. This flexibility allows system designers to match project targets while keeping a consistent mechanical format.
Enhanced energy yield from limited space: Panel efficiency up to 21.3 percent makes better use of available roof area. More kilowatt hours can be produced per square meter, which is valuable for urban and space constrained sites.
Reliable polycrystalline construction: Polycrystalline cells provide stable performance and proven long term durability. This technology supports predictable output and helps maintain system reliability throughout the panel lifetime.
Robust mechanical design: A tempered glass front with 3.2 mm thickness protects the cells from impact and weather. The anodized aluminium frame improves rigidity while keeping the module weight at only 22 kilograms.
Easy integration into modern systems: With a maximum system voltage of 1500 V and a series fuse rating of 20 A, the panel fits many string inverter designs. Standard 4 mm² cables with 1200 mm length simplify connection and array wiring.
Sunlight hits the polycrystalline cells of the HD Solar HD-66HPH-415M and is converted into direct current power. Each of the 132 half-cut cells contributes to the overall voltage and current produced by the module. At standard test conditions, the panel delivers 415 Wp with a voltage at maximum power of 38.2 volts. Current at maximum power reaches 10.87 amperes, while open circuit voltage is rated at 45.4 volts. The electrical output passes through the IP68 rated junction box and three integrated bypass diodes. These diodes help limit power loss under partial shading and reduce the risk of localized hot spots. Factory installed 4 mm² cables carry the generated energy onward to the string wiring and inverter input. The inverter then converts the direct current into grid compatible alternating current for onsite use or export. Thermal characteristics and temperature coefficients keep performance more stable across varying operating conditions. This process runs silently and automatically whenever enough solar irradiance is available on the module surface.
Polycrystalline energy conversion: The panel uses polycrystalline silicon cells to absorb incoming sunlight and create charge carriers. As photons strike the semiconductor material, electrons move and form a direct current flow across the cell circuits.
Half-cut cell architecture: The 132 half-cut cells are arranged to reduce resistive losses along the busbars. This design also improves shade tolerance because only part of the module is affected when one region is shaded.
Thermal and electrical protection: The junction box with IP68 protection secures the electrical connections against dust and moisture ingress. Three bypass diodes and defined temperature coefficients help maintain safety, power stability, and long term reliability.
