490W+ High Power with 20.8% High Efficiency

Based on the high volume 158mm third-cut monocrystalline PERC cells, the Tallmax module contains several innovative design features allowing high power output of 490W. Excellent temperature coefficients and low irradiation performance combined with square mono cells and the MBB technology enables modules efficiency up to 20.8%.

The 3.2mm AR coated glass layers and custom frame design enables ease-of-use and compatibility with standard installation methods for utility and C&I applications.

Integration of Innovative Technologies: High-density Interconnect Technologies and MBB

Trina Solar's research and development team has developed an innovative multi-busbar technology that enables increased light absorption. The 1500V system voltage and low current third-cut cell technology integration allows more modules per string, thus reducing BOS costs and higher power generation capacity per watt.

Smart Solar Solution: Modules on Trackers with Inverters

The TrinaPro solution integrates the customized TrinaTracker with these Tallmax modules and mainstream inverters. They enable optimized performance for utility/C&I applications.

With just a 2% LID and 0.45% annual degradation rate, these third-cut cell modules deliver low currents and higher lifetime energy when paired with a single-axis tracker. An adaptive tracking algorithm brings extra performance gain of up to 2%.
