Trina Solar US is proud to announce the launch of TrinaProtect, a bundled 25-year product and 25-year power warranty for Trina’s high-powered, all-black 430W Vertex S+ residential PV modules. This warranty program is only available in the United States. 

While Trina Solar has already offered a 25-year power warranty, TrinaProtect now extends the residential module product warranty from 12 years to 25 years. This warranty extension can provide additional protections and greater peace of mind for homeowners and installers alike. 

With decades of experience in PV manufacturing and R&D, Trina has been a pioneer in the solar industry, and the new warranty further exemplifies this. The power warranty guarantees that the module’s energy output will remain above a certain threshold. Now, the product warranty guarantees the module’s performance for the warranty’s duration of 25 years.

Warranties from other solar module manufacturers have restrictions or can be otherwise exclusive. Some solar manufacturers require taking part in a training program or having installers meet a volume requirement to extend their warranty for an additional five years. 

The Trina Protect 25-year product and power warranties:

  • apply automatically at purchase, with no strings attached

  • have no exclusivity, registration, or any extra training involved in order to qualify

  • have a simple, straightforward process that’s easy for customers and installers


Now residential solar installers have access to premium solar modules at affordable prices with 25/25-year warranties. And with the launch of Trina's Vertex S+ line in 2023, homeowners have access to industry-leading power generation and unprecedented value. 


Bringing added protection and total peace of mind 

Homeowners looking to install rooftop solar panels want to know they’re getting more than just a renewable energy source; they also want to ensure it’s reliable. Having a good warranty attached to the solar panels can help ease homeowners’ minds when they decide to invest in a solar PV system.

Solar panels, in general, already have a well-earned reputation for reliability. A study by the National Renewable Energy Laboratory (NREL) found that, on average new solar panels have an annual failure rate of only 5 in 10,000. This means a standard solar panel has about a 0.05 percent chance of failing. Over the 25 years of a module’s life, this translates to a 1.25 percent chance, which is extremely low.

But even that little bit of a chance can be too much of a risk for some homeowners. That’s why the product and power warranties provide additional peace of mind. 


Industry-Leading Bankability in a Residential Solar Solution

TrinaProtect is part of the Trina Solar US Advantage residential solution. The US Advantage helps installers deliver unparalleled solar value for homeowner customers with the 430W Vertex S+, which uses n-type TOPCon 210mm PV technology to give installers the unrivaled versatility and flexibility of smaller yet more powerful panels, and with its experienced US-based teams for sales, operations, logistics, finance, tech, and support.

And it's all backed by one of the most bankable and reliable PV module manufacturers in the world. Trina is the only OEM to receive a full bankability ranking for seven consecutive years by 100% of respondents in Bloomberg New Energy Finance's (BNEF) annual bankability survey. PV Evolution Labs' (PVEL) Reliability Scorecard has recognized Trina Solar as a “Top Performer” for eight consecutive years. The PV ModuleTech Bankability Ratings report released by PV Tech has ranked Trina's modules as "AAA" — the highest ranking — for the past four quarters.  

Altogether, the extended warranties and proven reliability of Trina’s modules mean suppliers, distributors, and installers can provide their customers with sleek and affordable modules from a trusted brand.
