About product

TSM-DE09.05 is part of the Trina Vertex Series — one of the most recent made by Trina Solar. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

To further boost the performance, Trina Solar employs half-cut cell technology. Each of the panel’s 120 cells is only half the size of a traditional solar cell. This grants TSM-DE09.05 lower resistive losses and better shade tolerance. The efficiency of this model reaches 20.5% — well above the market’s average. Trina Solar paid as much attention to durability as they did to performance. TSM-DE09.05 is guaranteed to retain at least 91% of output after 15 years. Product warranty for this panel lasts 15 years.

  • 395 W power output
  • 120 half-cut PERC cells
  • 20.5% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 15-year product and 15-year performance warranties

Higher efficiency of up to 20.5%

TSM-DE09.05 guarantees the highest power output. PERC technology and potent antireflective coating result in 20.5% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Keeping the cool in high temperatures

TSM-DE09.05 manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.34% in efficiency, allowing you to make the most of the sunniest hours.

High quality standards

Trina Solar strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Reliability and degradation resistance

Trina Solar guarantees limited degradation over the ensuing 15 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.50% yearly after that. After the 15 years are over, your modules will still show at least 91% of nominal capacity. A substantial 15-year product warranty is also included with this 395 W Trina Solar solar panel.

A panel that can handle hail, wind and snow

The 1.18" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 2400 Pa load, whereas the back side can withstand a 2400 Pa load.

These panels are sleek, and I appreciate that the installer added a skirt to the bottom of them. These all-black Trina panels became even more aesthetic

Other panel firms come and go on a regular basis. They boast 25- or 30-year guarantees, but if the manufacturer goes bankrupt, customers have nothing to rely on. Trina Solar was founded before my birth and will continue to operate long after my death. That gives some credence to the 25-year guarantee they provide.

When do you expect to have these back in stock? I would like to order 4 of them.

The panels are currently in stock.
I am looking at purchasing 40 solar panels of about 300 W for our blueberry farm. We intend to use micro inverters. We are looking at 300 W panels. I would also consider purchasing a frame for the panels. It can sit on the ground. Any suggestions? Do you sell a kit meeting the requirements noted above? How much $? Ronny Green

Yes, we have multiple 12 kW solar kits that include all you'd need for your project. To browse our turnkey solutions, please click on "Systems" at the very top of this page.
Our PV system uses the Trina TSM 320DD06M.05 (11) solar panel. One of them was damaged by a tree limb and will need replacement. Are they available or is a suitable replacement available? The system is 8,000 watts total.

Currently we don't have this model in stock. Typically, mixing panels with different specs is not recommended. We need more details about your system to determine whether replacing it with a similar model is optimal.


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
