The Trina TSM-445NEG9RC.27 is a 445W bifacial solar panel built on N-type i-TOPCon cells with dual-glass construction and an all-black finish. It rates 22.3% module efficiency across 144 half-cut cells, and its rear side can add output when the mounting and the surface below reflect light back onto it. That puts it among the higher-output residential panels, where a smaller count of modules covers the same roof area. It suits homeowners and installers who want maximum watts per square meter and a clean black array, and who can mount it with rear clearance for the bifacial gain. Buyers should weigh the bifacial upside against the fact that rear-side output depends entirely on the installation.

The Trina TSM-445NEG9RC.27 is a 445W all-black bifacial solar panel. It uses 144 N-type i-TOPCon monocrystalline cells and has a module efficiency of 22.3%. Trina identifies this module series for residential and commercial rooftop installations.
The panel has heat-strengthened glass on both the front and the back, in a 30mm anodized aluminum frame. It is tested for loads up to 5,400 Pa on the front and 4,000 Pa on the back. The junction box is IP68 rated.
Because the panel is bifacial, it captures sunlight on both sides. Light reflected onto the rear can add power. The 445W rating is the front-side output under Standard Test Conditions and does not include bifacial gain. Reference values show about 467W with 5% backside power gain and about 490W with 10% backside power gain. Actual gain depends on surface reflectivity, mounting height, panel spacing, shading and rear-side exposure.
