Trina Solar panels: the complete review

Reading Time: 4 minutes

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, before launching a 600 Watt (!!!) panel in July. The company manufactures all of its solar products in China, and is a popular brand featured in quotes to solar shoppers comparing their options on the EnergySage Solar Marketplace.


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

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

EnergySage has reviewed the product specifications of each Trina solar panel series to make your solar research process easier. As the leading online marketplace for homeowners considering solar, EnergySage 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 four key metrics that you should review as you evaluate solar panel quality: efficiency, performance, warranties, and price. EnergySage 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 on the EnergySage Solar Marketplace.

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%.

Performance (Temperature Coefficient)

For this portion of EnergySage’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 SPLITMAX TSM-320 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.

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, but also offers up to a 25-year warranty with some products.

How much do Trina Solar panels cost? 

For many homeowners, the final decision around the solar equipment you choose rests on cost. The total price you pay for a solar energy system with Trina Solar panels will vary depending on the other equipment (such as inverters and mounts) used in the installation, as well as the characteristics of your roof.

To identify the range of prices for Trina Solar systems, we analyzed quotes including Trina Solar solar panels that homeowners received from installers on the EnergySage Solar Marketplace. Most Trina Solar systems are typically priced between $2.48 and $3.16 per watt, which makes them a good value in the market for home solar.

This means that, for a 6 kW system, your gross cost (before you subtract any tax credits or other incentives) would be anywhere from $14,880 to $18,960. Additionally, most homeowners end up paying much less than the total gross cost. With the 26 percent federal tax credit for solar, which everyone is eligible for, a 6 kW system with Trina Solar would cost anywhere from $11,011 to $14,030. There are plenty of state-level solar incentives and rebates that can help you reduce upfront costs even further. 

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 in the EnergySage Solar Marketplace, 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 on the EnergySage Solar Marketplace, you’ll find the right combination of price and quality that meets your needs. Many of our qualified, pre-vetted solar installers offer Trina Solar solar panels in their quotes to EnergySage users.

    My system has been down since Nov. 2019. All the panels are defective and the date for having new panels placed on the house is 6 month to a year. Totally unacceptable.

    I would like to add my +1 to the warranty hell stories of the comments above. 3 months so far of no solar production and I’m still waiting. If you’re reading this thinking of buying a Trina Solar based system, I would advise looking elsewhere.

    Regarding Trina solar panels, I also agree with Ms Waldowski and Mr Lind. We have been without solar production since August 2018. After several frustrating months of poor field service and diagnosis, warranty replacement orders were issued. Still no response from Trina as of May 2019. Our field service provider told us that several homes in our area were in the same predicament, waiting for replacement panels. This is unbelievably disappointing and frustrating. Feeling pretty helpless.

    Regarding Trina solar panels, I have to agree with Ms Waldowski (above). We were notified in November 2018 that all of our panels had failed and would need to be replaced. Apparently 1000s of systems have failed due to manufacturing defects. Tesla/Solar City was/is our installer and they apparently have no capability of telling us when our system will be replaced. (As far as I can tell, Tesla/Solar City does not support a web site, hot line, or other method for offering information regarding the number of systems that have failed, or progress in system replacements.). This whole experience has been incredibly disappointing, especially because our system was specifically sized to cover not only our basic household needs but also the charging of a brand new Tesla Model S, the arrival of which was planned to coincide with the installation of the crappy Trina solar panels.

    I’m pissed.

    PROMISES ARE CHEAP. WE HAVE BEEN WAITING 3 MONTHS FOR TRINA TO SEND THE REPLACEMENT PANELS UNDER OUR WARRANTY. OUR CLAIM WAS APPROVED 01/02/2019 – WE CAN’T GET ANY STATUS REPORTS. WE ARE AWARE OF ANOTHER FAMILY IN THE SAME SITUATION.

    WARRANTY ISN’T WORTH MUCH IF IT NEVER IS FULFILLED.

    I AM TOTALLY DISGUSTED. I WILL BE PUBLISHING ALL MY DOCUMENTATION IN TWO WEEKS IF WE STILL CAN’T GET ANY SUPPORT FROM TRINA SOLAR. PLEASE DONT ENCOURAGE PEOPLE TO PURCHASE FROM THIS COMPANY
