Trina - Solar Panel Reviews

About Trina

Trina Solar is one of the largest manufacturers of solar panels in the world. As at early 2023, cumulative shipments of Trina Solar panels had exceeded 120GW.

Trina Solar is a Chinese company, with 23 offices worldwide - including one in Sydney. It employs 20,000 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 a factory in Thailand and another in Vietnam.

Trina Solar Is A Tier 1 Manufacturer

The company has scored 100% in the Bloomberg New Energy Finance (BNEF) Bankability Survey for seven consecutive years. So, financially it seems a a pretty solid firm. But what about the quality of its products?

Trina is a well respected name in solar panel manufacturing. It produces quality solar panels and offers a 15 - 25 year product warranty depending on the module. 25 year product warranties were once the exclusive realm of of high-end (most expensive) panel manufacturers, so to see a "budget" (but good quality) player join that club was really impressive and a sign of things to come.

Trina Striving For Sustainable Solar Panel Manufacturing

Solar manufacturing is a resource-intensive business. Trina says it was able to reduce both its electricity and water consumption by over 60 percent from 2015 to 2020. But the efforts didn't stop there. 

Power consumption per unit of product output decreased 42.4% in 2021 compared to 2020. As for water and also compared with 2020, consumption per unit decreased 46.2% in 2021. Compared with 2020, greenhouse gas emissions per unit produced decreased 32.2% in 2021. These results aren't just good for the planet, but also the company's bottom line.

Trina is member of PV Cycle, ensuring products are recycled at the end of their life in countries where PV Cycle operates - which doesn't appear to include Australia at this point. 

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 405W 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.

That was subsequently topped by a 440W panel, then a 475-Watt Vertex S+ module released in 2025.

In addition to the boost in power, the new Vertex S+  panels are accompanied by an even better product warranty - 25 years; although Trina also boosted warranty on some of its Vertex S panels to 25 years in August 2022. The Vertex S+ also offers a 30 year performance warranty, with first-year degradation at 1% and annual degradation thereafter at 0.4%.

Something else differentiating the two product lines is the Vertex S has a conventional backsheet and P-type cells, while the Vertex S+ boasts dual glass and N-type cells.

Salt Mist Corrosion Resistance

All Trina Solar panels state on their datasheets they are corrosion resistant.  Certifications for corrosion resistance can be found on Trina’s download page.

Warranty Procedure For Orphaned Trina Customers

If you have purchased Trina solar panels from an installer who has since gone out of business, the responsibility for warranty claims shifts to Trina. Their customer service line in Australia is 1300 874 627, and Trina have advised that orphaned customers can lodge panel warranty claims through their online portal available here. The company will arrange for an installer in their network to replace the panels under warranty, with labor costs being covered by their warranty.

Trina Solar Panels Are A Good Choice

I have no problems recommending Trina solar panels as they offer a cost effective combination of price and reliability. While there are panels out there I consider likely to be more reliable, you will have to pay a premium for them. On the plus side, when there have been issues in the past, Trina Solar has so far proven to be quick in rectifying them under warranty.

Trina is a popular brand with Australian installers, taking out first place in SQ’s Installers Choice Awards for the best solar panels in 2023 (budget category); a ranking the company also achieved in 2022 and 2021. In the 2023 awards, Trina ranked third for the best after-sales support.
