Product Description
1.Shingled module technology-process
Compared with the normal module process, the shingled process has different interconnect materials, and the process is simpler and more reliable, avoiding defects such as offset welding of the ribbon.

3. shingled module-Better ability to melt snow
Vertical installation, shingled module cells series and parallel structure, as soon as the snow on one string of cells melts, the module is ready to work, the temperature rise during work further accelerates snow melting. It can effectively increase module power generation time.
4. shingled module- load-resisting capacity
Under the load of IEC 5400Pa, shingled has no new micro-cracks, although both shingled module and half-cell module passed the test(attenuation < 5%)
High load resisting capacity reduces the production of micro-crack during transportation and power station installation
