Trina-390W Solar Panel 120 Cell TSM-390-DE09C07

About product

TSM DE09 C07 is part of the Vertex S Series — one of the most recent made by Trina Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. 

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. Trina Solar made solar cells in TSM DE09 C07 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. As a result, the panel achieves an impressive efficiency of 20.3%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Trina Solar provides a 25-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

More power and efficiency

An already high efficiency of 20.3% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, TSM DE09 C07 outputs 390 W of power.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just 0.34% for every 1.8°F increase over 77°F.

Quality and reliability

TSM DE09 C07 is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

Improved frame design

TSM DE09 C07 design makes it suitable for both residential and business rooftops. The use of a strong 1.18" frame composed of anodized aluminum boosts durability and strength. The model can withstand a significant snow load of up to 6000 Pa. The panel's back can withstand 4000 Pa, guaranteeing that your system will resist even the fiercest winds.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at Trina Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.
