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?
12/26/2022, 02:56
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.


How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
