About product

TSM-385DE09C.07 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-385DE09C.07 two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 20.03% — well above the market’s average. 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 paid as much attention to durability as they did to performance. TSM-385DE09C.07 is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 25 years.

  • 120 half-cut PERC cells
  • 385 W nameplate capacity
  • 20.03% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 25 years of product and 25 years of performance warranty

Increased power and efficiency

PERC technology improves on an already high efficiency of 20.03 percent. The manufacturer created an efficient and highly durable model by adding a robust PID resistance and unique glass lamination on top. TSM-385DE09C.07 produces 385 W of power under standard test conditions.

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 0.04% for every 1.8°F increase over 77°F.

High quality standards

Trina Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

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.

Certified for the worst environmental conditions

TSM-385DE09C.07 is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 6000 Pa on the front and 4000 Pa on the back. This durability is mostly owing to the 1.18" thick anodized aluminum frame and a layer of protective glass.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Trina Solar engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.
