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.

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.

FAQ

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
