Description
Trina 445W Bifacial N-Type Solar Panel | Up to 500W Bifacial Output (Full Black) | TSM-445NEG9RC.27
The Trina 445W all-black bifacial solar panel combines high-efficiency N-type i-TOPCon cells with durable dual-glass construction and a sleek appearance. Delivering 445 watts of rated front-side power and 22.3% module efficiency, this panel is designed for residential and commercial rooftop solar installations where performance, space, and appearance matter.
Its bifacial design captures sunlight on both sides, allowing reflected light to contribute additional power when the mounting configuration and surrounding surfaces provide rear-side exposure.
Key Features
- 445W rated output: High power density helps maximize production where installation space is limited.
- 22.3% module efficiency: Converts sunlight into electricity efficiently within a compact footprint.
- 144 N-type i-TOPCon cells: Advanced monocrystalline cell technology supports strong performance, including under low irradiation.
- All-black appearance: A clean look for residential and commercial solar arrays.
- Bifacial energy generation: Rear-side light capture creates opportunities for additional output.
- Dual-glass construction: Heat-strengthened glass on both sides provides weather resistance and helps protect cells.
- Strong mechanical performance: Tested for loads up to 5,400 Pa on the front and 4,000 Pa on the back.
- Compact, manageable format: Measures approximately 69.37 × 44.65 inches and weighs 48.06 pounds.
- Full Pallet Quantity: 36 Solar Panels
Additional Power From Reflected Sunlight
The Trina TSM-445NEG9RC.27 can generate additional electricity from light reflected onto the rear of the panel. The manufacturer’s reference values show approximately 467W with 5% backside power gain and 490W with 10% backside power gain.
Actual bifacial gain depends on surface reflectivity, mounting height, panel spacing, shading, and rear-side exposure. These reference outputs are conditional and do not replace the panel’s 445W front-side STC rating.

Frequently Asked Questions
Does the 445W rating include bifacial gain?
No. The 445W rating is the front-side output under Standard Test Conditions. Rear-side illumination can contribute additional power.
Can this panel be used in a rooftop solar system?
Yes. Trina identifies this module series for residential and commercial rooftops. System design must account for inverter compatibility, mounting requirements, and applicable local approvals.
What does dual-glass construction mean?
The panel uses heat-strengthened glass on both the front and rear to protect the solar cells and support long-term durability.
