About product

Trina Solar  TSM DE15V is a PV module fit for both residential and commercial applications. Trina Solar engineers made the TellMax series durable and efficient while minimizing the amount of useful space required for their operation. 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. 

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 DE15V lower resistive losses and better shade tolerance. Not surprisingly, the efficiency of this module is quite high – 20.4%. Trina Solar offers 12 years of product warranty and guarantees 84.8% of original performance after 25 years of operation. 

  • 480 W power output
  • 252 half-cut PERC cells
  • 20.4% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties

High efficiency of 20.4%

Trina Solar TellMax panels take full advantage of the company’s technologies that have won Trina Solar multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

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 DE15V 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.

Enhanced frame design

 TSM DE15V design makes it ideal for residential and commercial rooftops. Strong 1.38" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 2400 Pa, ensuring that your system will survive the strongest of winds.

After comparing several panels in terms of price, performance, warranty, and overall value, I settled on installing 45 Trina 480-watt panels. I've been using them for over a month now, and they've been flawlessly reliable the entire time. As a bonus, Trina also has excellent customer service. I needed some clarifications, and they were happy to oblige. Additional panels, if I ever need them, will be Trina.

There are plenty of mounting systems on the market, but our store specializes in panels and solar equipment. If you need a turnkey solution, please press "Systems" at the very top of this page.
What size Charge controller and how many 100 aH batteries do you recommend for 40 of the Trina 480 watt panels? Is there a delivery charge if I pick it up at your Fort Lauderdale location?

The configuration of your system will depend on your needs. You can choose to go without a storage system altogether or opt for multiday storage. We do not charge for delivery if you pick up the panels at one of our fulfilling centers.
