TSM-400 DE15M(II) 400W 144-cell Solar Panel Integration

This Tallmax M module integrates various technologies like half-cut cells and multi-busbar, with the highest power up to 415W. Multi-busbar can shorten the current conduction distance by over 50% and thus lower the internal ribbon resistance loss. With finer and narrower busbars, more sunlight can be reflected back to the round ribbon, thus increasing energy efficiency. Besides, the unique circuit design of half-cut cells can reduce power loss caused by ribbon resistance to 1/4 compared to full cells, which results the decrease of electrical resistance within the ribbon and finally improves the overall module efficiency

Higher return on investment thanks to higher power output

The output of this Tallmax M module is 15W higher than that of industry-typical 5BB PERC modules with the same specifications. Application of this Honey M module can remarkably reduce the number of modules employed in a power station, thus lowering corresponding cost of supports, cables, construction and land, improving the return on investment.

TSM-400 DE15M(II) 400W 144-cell Solar Panel  Exceptional reliability

The Tallmax M module is one of the industry’s most trusted modules. Low hot spot occurrence and half-cut cell technology can reduce failures, improving safety and performance. The application of multi-busbar cells results in more uniform loads to prevent stress, resulting in better performance even in case of slight cracking. Nowadays the market share of PV modules featuring MBB technology is dominant in the global solar industry.
