Photovoltaic panel 500W JA SOLAR JAM60D40-500/LB_BF bifacial (double-sided) - Black frame Deep Blue 4.0 Pro monocrystalline N-type

500 W Dual-Sided Panel, Designed for Efficiency and Durability

The panel utilizes N-type monocrystalline cells with a bifacial double-glass design—glass on both front and back. This not only enhances resistance to mechanical damage and harsh weather conditions but also enables the capture of reflected light from the ground, further increasing energy yield—especially when mounted above reflective surfaces such as white roofs, sand, or snow. In practice: even under low sunlight or shaded conditions, this panel generates more energy than conventional models.

Each cell is half-cut (half-cut) and equipped with 16-busbar (MBB) technology, which reduces resistive losses and improves performance under partial shading. For installers, this means more stable system operation under real-world conditions; for users, it translates to higher annual energy yield without requiring perfect tilt angle optimization.

The black frame and uniform, dark aesthetic ensure seamless integration with modern roofs and facades—unobtrusive yet highly effective. The glass-glass construction with anodized aluminum frame guarantees corrosion resistance and long-term structural stability. At 27.3 kg, the weight is consistent and predictable—no surprises during transport or installation.

Performance in Extreme Conditions

The temperature coefficient of power is -0.29%/°C—among the best in its class. This means that even under high rooftop temperatures (e.g., +65°C), the panel loses less power than competing models. At an ambient temperature of 35°C, its output remains close to nominal—critical during summer months.

Additional features:

• Power tolerance: 0 ~ +3%—each module delivers at least 500 Wp, often more
• Bifaciality up to 80%—the rear side generates an additional 20–30% energy under optimal conditions
• Maximum system voltage: 1500 V—enables longer string lengths, reducing cable losses and installation costs
• IP68 junction box with MC4-EVO2A connectors—ensures watertight integrity and safe connections even in rain

Warranty and Reliability

The manufacturer offers a 12-year product warranty and a 30-year linear power output warranty, meaning the panel will retain over 85% of its initial power after three decades. This is not marketing—it’s the result of N-type technology, which virtually eliminates LID (Light Induced Degradation) and oxygen-related cell degradation.

Also note: the module complies with IEC 61215, IEC 61730, and UL 61215/61730 standards—certifying its approval for use in both the EU and the USA. Mechanical load ratings of 5400 Pa on the front (e.g., heavy snow accumulation) and 2400 Pa on the rear ensure safe operation even on flat roofs or ground-mounted systems.

There is no room here for vague claims like “high quality” or “solid construction.” This is glass on both sides, an anodized black frame, N-type half-cut cells, and MC4-EVO2A connectors. These are not promises. These are facts.
