Highly-efficient Half-Sheet Solar PV Modules

Adopting multi-main shed (MBB) half-sheet technology, the output power is away from 550W, and the conversion efficiency of the module reaches 21.28%. Anti-PID performance. The PID(Potential Induced Degradation) resis-tance authority test (85 ° C/85% RH, 96 hours) under the harsh conditions of the industry minimizes the chance of degradation caused by the PID. 10/11 main grid cells. All the cells are upgraded to 10/11 main grid cells, which have stronger current collection capability and more stable power. Mechanical load. Certified for wind load of 2400 Pa at the back of the assembly and snow load of 5400 Pa at the front. Excellent low light power generation performance. Excellent electrical performance output under low light conditions. Low light attenuation. Rigorous ATLAS steady-state light testing ensures excellent photoluminescence performance for each batch of modules. Rigorous EL testing. Spatial resolution is less than 0.5mm, and more than two EL tests before and after to ensure zero defects inside the component. Fully automated component production line. Guarantee 100% on line production and 100% online inspection to ensure consistent product quality. ．100% fully automatic production line, ensuring 100% in-line inspection on the production line. Effectively avoiding the risk of hidden cracks and inherent defects, improving efficiency, reducing manual errors, precision welding, and maintaining uniform product quality standards. ．First-class photovoltaic testing center, up to 38 valid tests and experiments to ensure product quality. ．High, medium and low current classification to improve system output performance. ．Two EL tests before and after. 12-focus EL to overcome depth-of-field differences, spatial resolution of 0.4-0.5mm high and low currents are tested separately, with zero tolerance for quality risks. ．Long-term reliability testing. The PV testing center follows the standard of 3 times thousand conventional tests to guarantee the longer life cycle of the modules.
