TaleSun 445W Bifacial Full Black Solar Panel – TM7G54M | High-Efficiency N-Type TOPCon Module

The TM7G54M 445W bifacial full black solar panel delivers premium performance, durability, and aesthetics in a compact residential- and commercial-ready format. Built with N-type TOPCon bifacial cell technology and 16BB half-cut cells, this module achieves higher energy yields, reduced degradation, and excellent low-light performance. Its dual-glass, full-black design makes it ideal for rooftops where both efficiency and appearance matter.

With up to 25% rear-side power gain depending on installation conditions and albedo, the TM7G54M 445W significantly lowers the levelized cost of energy (LCOE) while ensuring long-term reliability backed by industry-leading warranties.
