1.       They are designed according to IEC61215: 1993, the standard of International Electrician Commission and manufactured by using the advanced technology and equipments to ensure the stable power output and extra-long service life of 25 years.
2. A bypass diode is connected in series to each 18, 24 or 36 slices of solar cell in a large-power module to prevent the hot-spot effect.
3. The solar cells with anti-reflection surface coated with dark blue ammoniated silicon or titanium dioxide are used for modules to ensure their good appearance and high efficiency.
4. The modules pressed by layers of toughened glass with high transparency, EVA with good anti-aging performance, imported solar cells with high conversion efficiency and TPT available to be repaired repeatedly have excellent durability, good resistance to hail and water.
5. The frames made of high-quality aluminum alloy have high rank of wind-resistance and are constructed in reason to be installed easily.
6. The sealed multi-purpose connecting-boxes with good waterproof performance are used to provide a variety of connection mode.
7. Every module is to be inspected for appearance and tested for electricity performance to ensure its excellent quality.
