Features
Advanced Design and Technology
The 16 busbar solar cell design enhances light absorption, achieving a 25.1% efficiency. The 64-cell monocrystalline module delivers a 250W maximum power output. High-transmission, AR-coated tempered glass maximizes sunlight capture and ensures durability. A 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 panel offers excellent low-light performance, effective even on cloudy days or during mornings and evenings. Over 30 in-house tests (including UV, TC, HF) 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.

Curve Characteristics
The 'Curve Characteristics' section displays two graphs: an I-V (Current vs. Voltage) curve and a P-V (Power vs. Voltage) curve. The I-V curve shows current decreasing as voltage increases, starting from approximately 13.7A at 0V and dropping to 0A at around 22.8V. The P-V curve shows power increasing from 0W at 0V, peaking at 250W at approximately 18.9V, and then decreasing to 0W at around 22.8V. The X-axis for both curves represents Voltage (V), and the Y-axis represents Current (A) for the I-V curve and Power (W) for the P-V curve.
