What solar panel models does Trina Solar offer?

Vertex S+ | Vertex S | Residential | |
---|---|---|---|
Power output | 420 - 445 W | 380 - 405 W | 310 - 380 W |
Maximum efficiency | 22.3% | 21.1% | 20.6% |
Cell technology | TOPCon | Half-cut monocrystalline PERC | Half-cut monocrystalline |
The Residential Series is Trina’s most basic option, featuring monocrystalline cells with a maximum power rating of 380 watts. While slightly below average in performance, it remains a solid choice, especially for homeowners looking for an affordable solar solution.
The Vertex S Series incorporates PERC solar cell technology, providing a slight boost in efficiency and performance compared to the Residential Series. However, it still falls within the average range in terms of overall performance.
Trina’s newest panel, the Vertex S+ Series, features TOPCon solar cells, a cutting-edge technology that delivers top-tier efficiency and performance. However, TOPCon panels are more vulnerable to water damage, which may be a consideration for homeowners in humid environments.
Despite not having the most impressive performance, Trina offers incredibly high-quality solar panels. Of the panels we reviewed for our best solar panels of 2025 list, Trina is the only one to get a perfect score for our PVEL third-party testing category. You can trust that when you put Trina solar panels on your roof, they’ll be durable and long-lasting.
Trina Solar warranties
While most of Trina’s solar panels offer average performance, its solar panel warranty coverage stands out. Trina provides a 25-year product warranty, surpassing many competitors that typically offer only 12-year warranties.
Additionally, Trina’s performance warranty guarantees 89.4% of the original power output after 25 years, ensuring long-term reliability. While some manufacturers offer even stronger performance guarantees, Trina’s coverage is still competitive.
Trina’s strong industry reputation further reinforces its warranty. Trina is one of the largest solar panel brands, with nearly three decades of operation in the solar industry. You can feel confident that Trina will be around to support any future warranty claims you have during your solar system’s 25-year lifespan.
How much do Trina solar panels cost?
Trina solar panels cost an average of $2.97 per watt of solar installed, or about $21,384 for a 7.2-kilowatt solar system, before solar incentives are applied. In general, Trina’s solar panels are cheaper than the national average cost of solar panels, which is about $3.03 per watt. If you’re looking for high-quality panels at a low price, Trina is the brand for you.
While Trina may be cheaper than most other solar panels, $21,000 is still expensive. Luckily, you can use solar incentives like the 30% federal solar tax credit to reduce the price of your Trina solar panel installation.
