Better occlusion response and lower risk of cracking.
P-type modules have a wide range of application scenarios, such as schools, hospitals, shopping malls, government cement roofs, old residential buildings, non-load-bearing cement flat roofs, etc.
This product is a single-sided single-glass module, module power: 535W ~ 555W. The maximum output power is 555W, the maximum module efficiency is 21.5%, the power output tolerance is 0~+5W, the first-year attenuation rate is -2.00%, and the annual power attenuation rate is -0.45%.

Product Performance

Product Features

1. The power of P-type modules leads the industry, and the conversion efficiency can reach 21.5%
2. The working temperature is as low as about 43℃, which improves the power generation efficiency
3. The field effect passivation material treats the edge, repairs defects and reduces the loss of slivers
4.Using ultra-thin polysilicon technology to reduce parasitic absorption of light by polysilicon and improve current density. The back adopts a stepped three-dimensional shape, which improves internal reflection, improves the metal contact performance on the back, and improves cell efficiency and bifacial ratio.
5. SMBB metallization technology effectively reduces the series resistance, and improves the tolerance of battery cracks, broken grids, and ruptures, thereby improving reliability.
6. Better low-light power generation performance in early morning, evening and cloudy environments
7. The good rigidity of the steel frame provides better support for the laminate, and has better crack resistance under the same mechanical load conditions.

R & D And Production

The product adopts high-automatic production line, and the product efficiency is at the leading level in the industry. 3 times 100% visual inspection: before lamination, after lamination, before packaging. 3 times 100% EL inspection: battery string, before lamination, before packing. 100% dielectric withstand voltage test: withstand voltage, insulation, grounding.
