Trina Solar Panels: Review


Trina Solar Energy is one of the largest producers of solar panels in the world, and was founded in 1997. Recently, Trina Solar Energy has been in the news for taking the power output of solar panels by first releasing a 500 Watt panel in February 2021, before launching a 600 Watt (!!!) panel in July 2021. The company manufactures all of its solar products in China, and is a popular brand featured in quotes to solar shoppers.


Trina Solar panel products: Vertex, Tallmax, and Duomax series

Trina Solar Energy offers several different series of solar panels. The most popular on Solar Era are the VERTEX and TALLMAX product lines.


Solar Era has reviewed the product specifications of each Trina solar panel series to make your solar research process easier. As the leading solar installer for homeowners considering solar, Solar Era is uniquely positioned to evaluate the technical specifications of Trina solar panels and help you compare them to other manufacturers on the market.


How Trina Solar panels compare to other panel manufacturers

There are 3 key metrics that you should review as you evaluate solar panel quality: efficiency, performance and warranties. Solar Era has developed Trina Solar reviews for each metric to help make your solar decision easier. We’ve also created a comparison of Trina Solar solar panels against other leading panel manufacturers that are frequently featured in offers to homeowners and businesses shopping for solar.


1. Efficiency

The term “solar panel efficiency” refers to how well a solar panel captures sunlight and converts it into useful electricity. In the same conditions, a high-efficiency solar panel will produce more electricity than a lower-efficiency panel of the same size. For this reason, a higher efficiency rating is generally preferable.


The efficiency of your Trina Solar solar panels will vary depending on the specific model that you choose for your system. Across Trina Solar’s solar product line, panels have an efficiency rating of 16.2% to 20.4%.


2. Performance (Temperature Coefficient)

For this portion of Solar Era’s Trina Solar reviews, we use the temperature coefficient to evaluate solar panel performance. The temperature coefficient is an indicator of how well your solar panel can handle less-than-ideal conditions. Solar panels, like other electronic equipment, perform better when they are kept cool (ideally around 25° C/77° F). The temperature coefficient tells you how much your panel’s performance will change during hot sunny summer days.


For every degree above 25° C (77° F), your solar panel’s electricity production will decrease by its temperature coefficient. For example, the Trina Solar TALLMAX TSM-DE15M(II) 400 panel has a temperature coefficient of -0.37%/°C. This means that, if the panel’s temperature increases by one degree from 25° C (77° F) to 26° C (79° F), its electricity production will decrease by 0.37%. If its temperature increases all the way to 35° C (95° F), electricity production will reduce by 3.7%.


Your solar panels will likely see more than a few hot and sunny days over the course of each year, so ideally, they will have the lowest temperature coefficient possible. Trina Solar panels have temperature coefficients between -0.41 and -0.36.


3. Warranties

Whether you’re buying a TV, a car, or solar panels, the manufacturer should stand behind their product with a strong warranty. A solar panel’s materials warranty (sometimes referred to as the product or equipment warranty) is a guarantee from the manufacturer that they will replace your panel if it fails as a result of manufacturing defects or environmental issues.


Most solar panel manufacturers offer a 10-year materials warranty, but some higher-end solar panels come with a 12, 15, 20, or even 25-year warranty. Trina Solar offers a standard 10-year warranty against any defects in their solar panels.


While Trina Solar panels don’t offer industry-leading efficiency or performance, they are a leading brand in terms of total solar installations across the world. The company is also featured in some of the least expensive solar quotes offered to solar shoppers, and can be a smart choice for homeowners who are interested in an economical solar panel installation.


How to find the best price on Trina solar panels

The best way to determine whether Trina Solar solar panels are the best solar panels for your home is to review multiple quotes with different solar equipment options before making a decision. When you compare all of your options with Solar Era, you’ll find the right combination of price and quality that meets your needs.
