About product


TSM 330 is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

Another advantage is the half-cut cell technology. TSM 330 has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Given its size and weight, TSM 330 efficiency of 19.6% is quite impressive. Trina Solar offers 15 years of product warranty and guarantees 92% of original performance after 25 years of operation. 

  • 120 half-cut PERC cells
  • 330 W nameplate capacity
  • 19.6% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 15 years of product and 25 years of performance warranty

More power and efficiency

An already high efficiency of 19.6% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, TSM 330 outputs 330 W of power.

Improved performance at hot temperatures

A high temperature coefficient translates to more energy as the temperature rises. Every 1.8°F increase over 77°F reduces the efficiency of your panel by just.

High quality standards

Multiple tests are part of the Trina Solar tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Trina Solar. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 92% of original performance after the 25 years are over. This 330 W Trina Solar solar panel also comes with a generous 15-year product warranty.

A panel that can handle hail, wind and snow

The 1.38" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 2400 Pa.

We went with them instead of our original plan, and we couldn't be happier with our decision. Mostly we paid attention to the reviews, and Trina has the most positive real reviews in our opinion

They were picked out by the installer on our behalf. To be honest, I can't say if they are good or bad, time will tell. But A1Solar were pleasant to deal with and very responsive. Panels arrived very well packaged and safe.

Do I have to pay online and pick it up at Lauderdale or I can just go to that location and pay and pick it up at the same time?

We do our business via online purchases. Our fulfilling centers are not equipped to process payments.
I am interested in connecting 3 of these panels to a 700w 72v dc brushless pool pump. it has a mppt also. Max voltage 150v Would 3 in series be enough panels or do I need more? Perhaps 6 in series parallel?

Please note that connecting solar panels directly is not advisable. This is all due to differing currents and voltages, as well as solar's high weather-dependance. It's hard to make suggestions without knowing the full specs of the pump and other elements of the system. Do not hesitate to give us a call or send an email.
