About product

Trina Solar 335W is a PV module that has 120 half-cut cells and comes with a sleek all-black design with almost invisible busbars. Together with proven reliability and high efficiency, the aesthetics make it very popular among commercial and residential customers. With a power density of 199 W/m2 this model permits to maximize available space. Reduced interconnection losses and low thermal coefficients increase energy yields.

  • Power Output: 335 Watts
  • 120 Cell, Monocrystalline
  • 35 mm black frame, black backsheet
  • 1000 Volts Max Voltage

Outstanding 19.7% Efficiency

Trina Solar 335W is a monocrystalline solar panel with a 19.7% efficiency. This is considerably higher compared to the industry’s average values. A low temperature coefficient of -0.36% allows this model to perform well under high temperatures. The efficiency falls a mere 0.36% for every 1.8°F above 77°F. This helps to maximize the final energy output.

A panel that will weather any storm

Trina Solar 335W passed more than 30 in-house tests to make sure the model can handle challenging conditions. Its front side can resist a load of up to 5,400 Pa and the rear has been tested for 2,400 Pa. The panels are also resistant to salt, acid, sand and ammonia.

Product and performance warranty

Trina’s engineers made the model less sensitive to light induced degradation: you can expect an output drop of up to 1.9% in the first year of use, but from the 2nd year to the 25th year, the average annual power decline will be no more than 0.6%. The manufacturer also offers a 10 year product warranty.

In my research I ended up with this model because it had the best price among the modules with comparable specs and sleek design. I ended up ordering from A1 because it had the best price. Everything went well, thank you

The exterior might not be the most important part in a solar panel, but given a choice I would stick with panels that look good. These are both high quality and good looking

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
