About product

JAM54-395MR 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.

Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. JA Solar made solar cells in JAM54-395MR two times smaller than the standard size, thus reducing power loss and improving low-light behavior. Given its size and weight, JAM54-395MR efficiency of 20.5% is quite impressive. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. JA Solar provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

  • 395 W power output
  • 108 half-cut PERC cells
  • 20.5% efficiency
  • 1500 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 25-year performance warranties


High efficiency of 20.5%

JA Solar JA S31 panels take full advantage of the company’s technologies that have won JA Solar multiple awards. This PERC option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Keeping cool in hot weather

Even at high temperatures, JAM54-395MR remains efficient. It loses just 20.2% efficiency for every 1.8°F over 77°F, letting you make the most of the sunniest hours.

High quality standards

JA 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.

Low degradation for a longer lifespan

These panels will lose no more than 2% of their power output in the first year of service. From the 2nd year to the 25th year, the average annual power decline will be no more than 0.55%. The module retains over 84.8% of its original output after 25 years. Guaranteed by JA Solar.

Enhanced frame design

JAM54-395MR design makes it ideal for residential and commercial rooftops. Strong 1.18" frame made from anodized aluminum increases durability and strength. The model can support a heavy snow load up to 3600 Pa. The back of the panel can handle 1600 Pa, ensuring that your system will survive the strongest of winds.


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 JA Solar employ smaller gauge wires to link the cells together, creating a seamless appearance.

These panels are of excellent quality and look identical to expensive ones made in the USA. They have a 25-year performance guarantee in addition to the 20-year manufacturer's warranty. It was a great decision to go with JA solar panels.

Nice-looking panels. It's still early on, but so far everything appears to function as expected. A1 did a great job delivering them on time and uncracked

Shipping starts at $250 for up to 8 solar panels, and goes up by $25 with every 4 modules on top of that. Some panels qualify for free shipping when ordering over 10 items.
Do you ship to Australia or Fiji?

I depends on the voltage of your battery bank. If you're planning to use a 48 V storage system, a 60 A charge controller should suffice.
