    Trina Tallmax M Plus TSM-380DE14A(II) 72-cell Solar Panel

Trina Tallmax M Plus TSM-380DE14A(II) 72-cell Solar Panel delivers high efficiency, quality, and reliability. These modules feature 72 Mono PERC cells and offer high-output performance for ground-mount installations. Tallmax M Plus is perfect for large scale installations and for projects with limited acreage as it is able to maximize limited space with top efficiency and high power density. Trina Tallmax M Plus TSM-380DE14A(II) 72-cell Solar Panel is certified to withstand the most challenging weather conditions with a 40 mm clear anodized aluminum alloy frame.

Higher Efficiency of up to 19.5%

Great power output and greater energy yields. Excellent performance at low irradiance, on cloudy days, mornings and evenings.

High Efficiency at High Temperatures

The low thermal coefficient produces greater energy production at high operating temperatures. The module provides a high energy yield at low NOCT = 44°C ( ±2°C).

Quality and Reliability

High-quality assurance due to stringent quality control. All modules have to pass 100% electroluminescence (EL) double inspection. Over 30 in-house tests (UV, TC, HF, and many more). In house testing goes well beyond certification requirements. PID resistant.

Low Degradation

A Low 0.5% annual degradation rate after an initial first-year degradation of 3% results in a performance guarantee no less than 80.7% of power output by year 25.

Enhanced Frame Design

The module structure ensures it is able to withhold a heavy snow load up to 5400 Pa and wind load up to 2400 Pa.

10 Year Product and 25 Year Performance Warranty

This module comes with a 10-year product warranty on materials and workmanship and a 25-year linear power output warranty.

These panels seem to be generating the expected amount of energy. I get a great energy output even during overcast days.
Excellent value for the money! Nice, high quality panels that perform very efficiently.
These panels are very thin and that was one of the main reason I chose Trina brand. They practically merge with the roof. Great aesthetics.
I am impressed with the service I received here. Customer support specialists answered all my questions when I called ( and I had to call a few times) and I received my modules within 6 days after placing order. Highly recommend.
