Trina - Solar Panel Reviews

About Trina

Trina Solar is one of the world's largest solar panel manufacturers. By the end of 2025, they had shipped more than 320 GW of solar panels worldwide.

Trina Solar is a Chinese company, with offices worldwide - including one in Sydney. It employs around 22,000 staff globally, most of whom are in China. The firm is based in Changzhou, which, as every schoolchild knows, is just a one-hour train ride from Shanghai. Well, maybe not every schoolchild knows that, but I'm sure all the schoolchildren in China who know it would add up to a hell of a lot.

In addition to Chinese manufacturing capacity, Trina has factories in Thailand, Vietnam, and Indonesia.

25 Year Product Warranties Available

Trina is a well-respected name in solar panel manufacturing. Its panels are reliable and come with product warranties from 15-25 years depending on model. These days, just about every Trina panel going on an Australian home should come with a 25 year product warranty. While 25 years is a long time, it's now the standard product warranty length for decent quality residential solar panels. 

Trina Is Aiming For Sustainable Manufacturing

Trina has consistently reduced its environmental impact per kW of panels produced. Its 2025 Sustainability report says energy consumption was down 53% from 2020, while its water use per kW was down 84%. The company has committed to 100% renewable energy use by 2030.

Trina Solar Vertex S And S+ Panels

Trina's Vertex family of modules was originally geared towards utility-scale applications. But in late 2020, the company unveiled the Vertex-S designed for rooftop solar installations that offered up to 405 W capacity. Then in March 2022, the firm announced Australia would be first in line for the even more powerful 425W Trina Solar Vertex S+ panel, which is also suitable for residential and commercial rooftops.

Trina subsequently introduced increasingly powerful Vertex S+ models, including a 475 W panel in 2025. In May 2026, it launched the Australian-exclusive Vertex S+ G3 range, ranging from 495-515 W, with efficiencies reaching 24.7%. These are dual glass panels, where the solar cells are sandwiched between two layers of tough glass. While they're glass on both sides, they are monofacial and only use light coming from one direction. 

The Vertex S+ G3 warranty allows it to lose 1% of its original capacity in its first year and up to 0.35% in each subsequent year. This means it should have a minimum of 88.85% of its original rated output after 30 years.

Salt Mist Corrosion Resistance

Trina generally publishes salt-mist corrosion certificates for its panels that are typically installed on Australian roofs. Their Vertex S+ G3 panels have passed IEC 61701:2020 salt-mist testing method 6. Method 6 testing is harsh, so going by that, they should be suitable for installation near the sea. However, under Trina's current written warranty, when these panels and a number of other Trina models are installed within 2km of the coastline or near inland saltwater lakes, they require Trina's evaluation and approval for the manufacturer's warranty to apply. Installers should obtain written approval before installing these models.

 Certifications for corrosion resistance can be found on Trina's download page. 

Warranty Procedure For Orphaned Trina Customers

If your original installer has gone out of business, you can contact Trina Solar Australia if you need to make a warranty claim. You can phone them on 1300 874 627, email [email protected], or submit a claim through their online portal.

Note that you are always covered by Australian Consumer Guarantees, which provide considerably more protection than the Trina written warranty.

Trina Solar Panels Are A Good Choice

We have no problems recommending Trina solar panels as they offer a cost-effective combination of price and reliability. One reason we're happy to recommend them is that, when there have been issues in the past, Trina Solar has been generally quick to rectify them under warranty.

Trina was voted Australia's best-value solar panel brand by SolarQuotes installers for four consecutive years, from 2021 through 2024. It also finished second for after-sales support in 2024. The survey changed format in 2025, switching to a single question about which brand installers would choose for their own homes. Trina finished fifth overall in 2026.
