About product


Among the newest offerings of Canadian Solar, CS3N 390MS is part of the HiKuBlack series. These panels use state-of-the-art technology to achieve high efficiency and dependability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells. 

To further boost the performance, Canadian Solar employs half-cut cell technology. Each of the panel’s 132 cells is only half the size of a traditional solar cell. This grants CS3N 390MS lower resistive losses and better shade tolerance. As a result, the panel achieves an impressive efficiency of 19.2%. The innovations made the appearance of the panel as impressive as the specs. A mere 1.38" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Canadian Solar paid as much attention to durability as they did to performance. CS3N 390MS is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 12 years. 

  • 132 half-cut PERC cells
  • 390 W nameplate capacity
  • 19.2% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 12 years of product and 25 years of performance warranty

Increased efficiency of up to 19.2%

CS3N 390MS ensures maximum power production. 19.2 percent module efficiency is achieved using PERC technology and a powerful antireflective coating. This is much greater than the norm, resulting in significant additional savings throughout the years of operation.

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 0.34%.

High quality standards

Canadian Solar stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Canadian Solar guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.55% every year after that. After the 25 years are over, your modules will retain at least 84.8% of their original performance. This 390 W Canadian Solar solar panel also comes with a substantial 12-year product warranty.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm CS3N 390MS. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 2400 Pa in the back. A layer of protective glass and 1.38" thick anodized aluminum frame are the primary reasons for its toughness.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at Canadian Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.

It's barely a week, and the system has been through a snowstorm already. No damage, kept working the whole time. We are very impressed. Canadian Solar, our installer, and A1Solar all did their jobs extremely well.

Each cell in these Canadian Solar panels is completely black, so the panel is uniformly black, which is very cool. I am pleased with the neat appearance and the secure installation by my installer. Our setup is far more aesthetically pleasing than the other solar panels in the area.

When investing so much time and money, you should use the best materials you can afford. You'll be happy you did. For me CS is as good as it gets

Just to make sure: can MC4 be used with these panels?

Yes, T4 connectors that are sometimes used by Canadian Solar are fully compatible with MC4.
can I buy just 1 panel for Projects and pick up in Sacramento

Yes, buying a single panels is possible if you opt for pickup. When you’re viewing a panel, a list of all available pickup locations is to the right under “Availability”.
Can I buy 3 390w panels if I pick them up in Orlando? The system only allows to order minimum 4.
12/25/2022, 01:03
Yes, if you opt for pickup, you can order as few as one panel.
