What Makes Trina Solar Panels Unique?

Alongside their quality, Trina Panels have a particular interest in sustainability, and that makes them a company worth keeping an eye on. The Silicon Valley Toxics Coalition issues an annual report on the behavior of photovoltaic manufacturers, ranking the best solar panels companies based on their social and environmental responsibility and commitment. Trina Solar Panel was granted first place in such ranking in 2014. In the following years, despite falling to third and then second place, they improved on their previous score, qualifying them as one of the most sustainable solar panel manufacturers in the world. Which is not only good for the environment and our planet, but for ourselves as well.

More recently, in earlier 2023, Trina Solar received a dual EPD (Environmental Product Declaration) from independent institutes who certify the sustainability of the company, from the impact on the environment, the materials used, the production process, transportation, and packages, and finally recycling.

In Trina Solar panel reviews, the way we tend to measure performance is through the temperature coefficient. Generally, a solar panel will perform worse in certain meteorological conditions, namely when temperatures are too hot. As a convention, the set temperature is 25 °C: if the temperature goes above that number, then the panel will start losing its efficiency. By how much? That is precisely determined by the temperature coefficient.

Let’s make an example: as you can see from the charts above, a Canadian solar panel has, on average, a temperature coefficient of about -0.35%, depending on the model. Let’s say we buy a panel with -0.36% temperature coefficient. Every time the temperature is one grade over 25, then the panel’s production will drop by 0.36%. As you can see, the drop is quite low. Although some other companies have managed to bring such coefficients even lower, we have to admit it is quite a decent result, so you should be more than content.


Solar panel efficiency is the ability of a panel to capture sunlight and turn it into electricity. Trina Solar reviews all agree on the fact that the company builds solar panels with a very good efficiency rate. Typically, standard panels have an efficiency range of about 14% to 18%, while, generally speaking, Trina Solar ones tend to go higher, ranging from 18% to an exceptional > 20%. Efficiency is one of the most important aspects to keep into consideration when buying a solar panel, and Trina Solar does a great job at leading the market in that.


Although it is difficult to calculate the exact price a solar panel will cost you, given that a lot is determined by the area in which you live in, the model you choose, for what type of building, etc., on average, a watt will cost you about $0.88. That would be an average of $5,282 for a system sized 6 kW. Price is one of the best things about Trina Solar, as it is relatively cheap while not compromising the quality of the product. It is also very competitive because, on the market, you might often find similar prices for panels not quite as efficient as the Trina Solar’s.

Keep in mind that the price does not take into consideration the possibility of receiving incentives and help from the government for your decision of investing in renewable and clean energy. To check whether you are eligible for these funds, and if so, how much, you can enter your postcode online and see what financial payments you might receive.


Trina Solar offers an average 12-year product warranty for any defect the panel might have in its first decade or so, while the performance warranty is longer and covers 2 years of use. Regarding this last point, the company guarantees a minimum of 83.1% output, which is not extraordinary–some companies manage to not fall below 90%–but still average and quite decent. The Vertex and Vertex S series receive 3 years more of product warranty.

Support and warranty has greatly improved throughout the years, and feedback from customers is very positive. This shows Trina Solar’s commitment to make even better products and give as much help to their consumers as possible.
