Features
Advanced Design and Technology
16 busbar solar cell enhances light absorption, achieving 25.1% efficiency. The 128-cell monocrystalline module delivers a 250W maximum power output. High-transmission, AR-coated tempered glass maximizes sunlight capture and ensures durability. The plug-and-play junction box allows for quick and easy installation. Industry-standard quick-connect cables support series and parallel connections.
Easy Installation and Versatility
The lightweight anodized aluminum frame is durable, corrosion-resistant, and easy to handle. Pre-drilled holes are compatible with ground mounts, Z brackets, pole mounts, and tilt mounts. The panel works seamlessly with both on-grid and off-grid inverters, making it ideal for high-end off-grid systems and mobile applications.
Superior Performance and Reliability
The solar panel offers excellent low-light performance, even on cloudy days or during mornings and evenings. Over 30 in-house tests (UV, TC, HF, etc.) guarantee durability and performance. A PID-resistant design and 100% EL double inspection prevent micro-cracks and ensure module integrity. It is certified to withstand 2400 Pa wind load, 5400 Pa snow load, and 35 mm hail stones at 97 km/h.
Long-Term Warranty and Support
A 25-year limited product warranty ensures reliability, and a 25-year performance warranty guarantees minimal degradation. Refer to the product warranty documentation for detailed terms.
Dimensions
The solar panel has a length of 60.6 inches (1540 mm), a width of 29.9 inches (760 mm), and a thickness of 1.2 inches (30 mm).

Curve Characteristics
A graph displays the relationship between Voltage (V) on the x-axis and Current (A) and Power (W) on the y-axis. The current curve starts at approximately 7A at 0V and decreases as voltage increases, reaching 0A at around 45V. The power curve starts at 0W at 0V, rises to a peak of approximately 250W at around 37V, and then decreases to 0W at around 45V.
