About product

Trina Solar 415W is a PV module that uses 144 half-cut cells manufactured using proven by time technologies. The model’s reliability, high efficiency, PID resistance and high wattage make it a good choice for commercial and industrial use, but residential clients can also reap the benefits it has to offer. Among the model’s strong sides are BOS costs reduction and improved low-light performance.

  • Power Output: 415 Watts
  • 144 Cell, Monocrystalline
  • 35 mm silver frame, white backsheet
  • 1500 Volts Max Voltage

Outstanding 20.4% Efficiency

Trina Solar 415W is a monocrystalline module with a 20.4% efficiency, which is a long stretch ahead of what conventional panels have to offer. Trina Solar 415W has a low temperature coefficient of -0.36%, which means that the module’s efficiency decreases just 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

This model is certified to work under harsh conditions. Its front side can resist a load of up to 5,400 Pa and the rear has been tested for 2,400 Pa. Special coating makes the modules resistant to salt, acid, sand and ammonia.

Product and performance warranty

With this panel, light induced degradation is less of a threat: you can expect an output drop of up to 1.9% in the first year of use, but starting from the second year it won’t exceed 0.6%. Finally, after year twenty five the panel will perform at 83.1% of its nameplate capacity or slightly better. The manufacturer also offers a 12 year product warranty.

I have them installed in Sacramento Valley. The sun is very active here and they generate a lot of power. I plan to add more of these to my setup in the future

Great customer service! I bought them for a project I’ve been working on since spring. They were bulkier than I expected but true to the dimensions on the website. I’m satisfied with the quality, but the panels could be smaller

I bought 12 of these for ground mounting on a farm. So far so good. The modules arrived in time and undamaged. It was a pleasure to deal with you guys

Among other things this technology reduces resistive losses, helps with the hot spots and improves low-light performance.


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
