JA Solar was founded in 2005, although they use much of the same technology as other solar panel manufacturers, but what sets them apart is the JA Solar panels efficiency rating. In this JA Solar panels review, we will dig into the specifics of the different solar panels inside out so that you can decide whether to purchase these panels or not.
JA Solar Panels Review – Are They Good?
1. JAM60S10/MR
A 120 half-cell 340W JA Solar panel is an excellent choice for a home system with a monocrystalline module that demonstrates 20.2% efficiency, shows higher performance in high temperatures, and decreased the risk of hot spots owing to the use of busbars and half-cells. The module is resistant to wind and snow load and the half-cut cell design with three bypass diodes gives a solid shading tolerance and looks fairly nice at a reasonable cost of roughly $120-$140.
2. JAM72S30/MR
It’s a 144-cell 550W panel that’s ideal for commercial and utility-scale installations. It’s one of the most powerful panels on the market, with an astounding 21.3% efficiency. Three bypass diodes reduce the influence of shade while enduring a front load of 5400 PA. Busbars and half-cut cells extend the life of a panel and increase the flow of current within it. In the JA Solar panels review, this item received generally positive comments from Internet users and is priced between $230 and $260.
3. JAM72D20/MB
This JA Solar panels specs include a bifacial solar module that is a 144-cell 465W solar panel typically used in larger-scale systems, but they can also be installed at home. The rear side captures the sun just as well as the front side, resulting in 30-35% more production and this particular model achieves 20.9% efficiency. It also has a lower degradation rate: a panel loses only 0.45% of its output each year.
What are the JA Solar Panels Specs?
JA Solar panels surpass the vast majority of their competitors when it comes to efficiency, and their module offers include monocrystalline, polycrystalline, high-watt, and half-cut cell designs.
JA Solar also produces 60 and 72-cell solar panels, such as the Cypress line. This includes all panels in this series exceeding the industry benchmark efficiency while in terms of price, JA Solar’s modules have one of the highest efficiency ratings. The specifications and JA solar panels size are as follows:

What is the JA Solar Panels Efficiency Rating?
JA Solar panels capacity has been improved and it offers a maximum efficiency of 21.2%. An efficiency rating of over 20% is considered very well in the industry, with conventional solar panels providing 15-20%. JA Solar panels have an average efficiency rating of 19.53%, almost 1% higher than other mid-range solar panels. When compared to other brands, JA panels have a similar efficiency rating at a lower starting price point. JA Solar offers many residential solar panel options with high-efficiency ratings ranging from 19%-22% on average.
JA sells both residential and commercial-sized solar panels. Its residential solar panels contain either 54 or 60 solar cells, while the commercial panels use 72 cells. JA Solar Panels review claims that it uses half-cut monocrystalline cells in its residential panels, which helps increase their efficiency. These panels generally use the same technology, with slight variations leading to different wattage and efficiencies. However, the product is more powerful despite having fewer cells meaning the panels are smaller in size but still generate a lot of electricity, making them a great choice for homes with limited roofing space. The table below displays the average efficiency of JA Solar panels compared with other renowned brands:
| Manufacturer | Average Efficiency |
| JA Solar | 19.53% |
| Trina Solar | 18.83% |
| Canadian Solar | 18.73% |
| Panasonic | 19.99% |
Note: The writer doesn’t claim the efficiency in the article, it is solely based upon the market research which could vary depending on the location and model ranges.
What is JA Solar Panels Capacity?
The average production capacity of a PERC module was around 5.03 kWh/kW while the new n-type module is expected to increase the capacity of the solar panel by 3.9 percent, improving the efficiency of the panel even further. JA Solar panels review portrays that these are very well known for their high power generation capacity and this keeps them ahead of the competition by constantly upgrading their products to introduce better quality panels.

What is JA Solar Panels Price Range? What is JA Solar Panels Price Per Watt?
JA Solar manufactures budget-based mid-range solar modules, which means their panels cost more than value modules but less than premium modules. Comparable modules are built by Trina Solar, Canadian Solar, Hanwha Q Cells, and others. When it comes to pricing, JA Solar appears to be on the affordable end of the market, with a price per watt ranging between $0.55 and $0.65. Prices for JA Solar are comparable to those of Trina Solar, slightly lower than those of Canadian Solar, but significantly higher than those of LONGi Solar, in addition, might represent the most efficient among affordable PV modules. To make things simpler, we divided JA Solar panels price range into simple categories based on watts:
| Capacity | JA Solar Panels Average Installed Cost |
| 10kW | around $12,404 |
| 8KW | around $7,731 |
| 6kW | around $5,800 |
The manufacturer’s high-watt modules ensure that you will need fewer panels to complete your solar energy system, resulting in reductions both in the context of the modules themselves and the overall cost of materials required to meet your energy requirements. JA Solar Panels also have remarkable power output and efficiency rates, which means clients will see a return on investment far sooner than less efficient competitors.

What is the JA Solar Panels Warranty Period?
JA Solar panels come with an amazing 25-year product guarantee that is significantly longer than industry standards, as well as a fantastic 25-year linear performance warranty, which is the greatest solar panel warranties that are available for mid-priced solar panels and better than many premium panels as well. The linear performance warranty means that the 390-watt MBB Half-Cell Modules’ performance is warrantied for 84.8% of the module’s original power output, relative to a typical industry average of 80%, which is a highly durable performance warranty in the industry and yet another fantastic reason to pick JA Solar.
The current Deep Blue 3.0 series from JA Solar provides an industry-standard 12-year manufacturer’s product warranty that safeguards against any manufacturing-related defects for the first 12 years. Additionally, productively a 25-year performance warranty provides an excellent guarantee of a minimum 84.8% power output rating following 25 years of usage. This puts it in line with many leading Chinese panels built with the common P-type PERC cells.
The next-generation Deep Blue 4.0X is a JA Solar panels size of 182 mm that will be constructed with higher-performance N-type cells as well as are covered by an extension of the 15-year product warranty. It also comes with the possibility to extend up to 25 years, whereas the performance warranty will be extended with a longer 30-year warranty period and a lower degradation rate of 0.4% per year, which equates to 87.4% after 30 years of use. Furthermore, JA Solar has several service locations around the world; however, JA Solar panels review asserts that there has been currently no permanent Australian assistance or service center.
