About product

TSM DEG15VC.20 is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

To further boost the performance, Trina Solar employs half-cut cell technology. Each of the panel’s 252 cells is only half the size of a traditional solar cell. This grants TSM DEG15VC.20 lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 20.2%. 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. Trina Solar offers 12 years of product warranty and guarantees 86.4% of original performance after 30 years of operation. 

  • 475 W power output
  • 252 half-cut PERC cells
  • 20.2% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 30-year performance warranties

Higher efficiency of up to 20.2%

TSM DEG15VC.20 guarantees the highest power output. PERC technology and potent anti reflective coating result in 20.2% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Keeping the cool in high temperatures

TSM DEG15VC.20 manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.34% in efficiency, allowing you to make the most of the sunniest hours.

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.

Reliability and degradation resistance

Trina Solar guarantees slow deterioration over the next 30 years. The performance will decline by no more than 2% during the first year and then by no more than 0.40% every year after that. After the 30 years are over, your modules will retain at least 86.4% of their original performance. This 475 W Trina Solarsolar panel also comes with a substantial -year product warranty.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm TSM DEG15VC.20. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 2400 Pa in the back. A layer of protective glass and 1.38" thick anodized aluminum frame are the primary reasons for its toughness.

I purchased 475-watt half-cut cell panels and am extremely satisfied with their output. A1Solar is one of the best stores I've interacted with in my whole career
