JA solar 390w review
60-cell Mono PERC Panels
These JA panels have a multi-busbar PERC cell design. The half-cut cells help to increase the power output, and reduce issues you can get with shading. This technology helps to keep the panel temperature low too, and reduce the risk of hot spots. The JA solar 390w that we review here, are Mono PERC Panels and have an impressive efficiency of 21%. JA Solar confidently back their products with a 30 Year performance guarantee, and also a 15-year product warranty. The JA Solar 390w are one of the best options in solar PV today.
In conclusion, choosing JA 390W solar panels can provide you with a high-quality and efficient solution for your energy needs, while also offering long-term durability and reliability. The panels are Suitable for Australian Conditions: JA 390W solar panels are specifically designed to perform well in Australian environments, with features such as anti-reflective coating that can increase light absorption and reduce energy losses.
JA Solar Panels Review: A Comprehensive Look at Performance, Efficiency, and Reliability
As the demand for renewable energy sources continues to rise, solar panels have become an increasingly popular option for homeowners and businesses alike. With numerous manufacturers offering a wide array of products, it can be challenging to determine which solar panels are the best fit for your needs. In this article, we provide a comprehensive review of JA Solar panels, examining their performance, efficiency, and reliability to help you make an informed decision
Performance and Efficiency
JA Solar, a global leader in solar technology, has consistently produced solar panels that exhibit high performance and efficiency. The company utilizes advanced technologies such as monocrystalline PERC (Passivated Emitter and Rear Cell) cells, half-cell technology, and Multi Bus Bar (MBB) technology, all of which contribute to the panels' superior performance.
Monocrystalline PERC cells offer better low-light performance and overall efficiency compared to traditional solar cells. The half-cell design reduces resistive losses and mitigates the effects of shading, further enhancing the panels' performance. MBB technology minimizes power losses by reducing the distance between busbars, thereby improving overall efficiency.
JA Solar panels are known for their high power output, typically ranging from around 340W to 375W, depending on the specific model. This high output makes them an attractive option for those seeking to maximize their solar energy generation.
Reliability and Durability
JA Solar panels are designed to withstand harsh weather conditions and have undergone extensive testing to ensure long-lasting performance. The panels are built using high-quality materials and adhere to strict manufacturing standards, resulting in a durable and reliable product.
The company stands behind its products by offering a 12-year product warranty and a 25-year linear performance warranty, ensuring long-term confidence in their solar panels.
Customer Reviews and Satisfaction
JA Solar panels have garnered positive reviews from customers worldwide, thanks to their high efficiency, reliable performance, and competitive pricing. Many customers have praised the company's commitment to quality and innovation, as well as their responsive customer service.
While no solar panel is perfect, JA Solar's dedication to continuous improvement and maintaining high standards has helped them stand out as a trusted brand in the solar industry.
Why is JA Solar different?
Most panel makers claim to have an “edge” that sets them apart from their competitors. This is what the glossy advertising says. However, JA Solar display that their claim of superiority, is no idle boast, and have shown that their products continue to improve with better cell design in their modules that help them meet or exceed many solar industry benchmarks, for both build quality and performance.
What are half cut solar cells about?
The JA design has a half cut cell structure. What this does is enable one half of a cell to work, even though the other half is shaded and not operating. It also makes the connections within the cell shorter, which increases the energy flow through the cell, and lifts its efficiency rate.
JA Solar panels are “PERC”. What is that?
You may well ask what on earth is “PERC”? Are you ready for it? What this acronym stands for is “Passive Emitter Rear Contact”. Again, you ask; what is that!? I’ll try to make this as simple as possible. A solar cell is made up of various layers of silicon that are sandwiched between light reflective layers. The top layer that faces the Sun, enables light to travel through it easily - but only one way. When the ‘captured’ light is between the layers it ‘bounces around’ and excites the ions in the silicon material. Its these ions that move through the layers to the connectors that can then channel them as electricity – as power. A “PERC” cell performs this sequence better than an ordinary solar cell.
How did JA Solar come about; What’s their story?
The JA Solar story began in 2005, in Beijing, China and quickly grew to be listed on the US NASDAQ by 2007. The company has come back into private hands under JASO Acquisition Limited. The firm now has 9 manufacturing plants in China, Malaysia and Vietnam with an annual production capacity of over 13GW. This places JA Solar as the third largest solar panel producer as of Q4, 2020. As of 2019, the company operates from 32 locations around the world, and employs about 22,000 people.
Does JA Solar have good warranty in Australia?
JA Solar recently increased their panel product replacement warranty to 15 years in Australia. This is in addition to the existing 30-year panel output warranty too. Many panels only offer at best a 12-year product warranty with a 25-year performance guarantee. So, it’s reasonable to say that you’re well covered with this brand. This is on top of any Australian Consumer Law provisions that apply as well. At the time of writing, we hadn’t heard of any issues whatsoever with JA Solar in Australia or elsewhere.
Does JA Solar have an office in Australia, and why is this important?
Firstly, Solar Power Panels only offers products that are well-established in the Australian Market. Over the years, as the solar industry grew, many companies arrived on the local market, they were products just handled through agencies and distributors. This caused many problems for those customers who experienced problems with their solar products, who then tried to get help back through either the installer, or the manufacturer’s agent. This arrangement did not end well for many people.
Its well documented that many solar companies of all sizes have come and gone, and left a trail of unhappy purchasers in their wake. If a customer was fortunate enough to have purchased their system through a reputable company, then there was always a strong possibility that that company would try and assist the customer even if the manufacturer or distributor had disappeared. This is great news for the end-user customer, but not at all great news for the reputable company, as they are left to underwrite and clean up someone else’s mess. Therefore, we as a solar retailer and installer will never buy to re-supply to any of our clients, equipment from companies that do not have a solid Australian presence, and a reputation for reliability, in the actual performance of their products, including the ease of dealing with them, should a warranty situation arise.
At the time of writing, JA Solar Australia Pty Ltd operates an office with a small staff at 755 Hunter Street, Newcastle West NSW 2302 Email: email@example.com
So, are JA Solar panels worthwhile?
Yes, at this time, there are more reasons to buy than not. The company and its products meet all the requirements price and performance-wise. In addition, their warranty appears to be sound. However, we haven’t heard of any issues of any kind and haven’t had to actually process any warranty claims through them. Which is probably a good thing!
In this JA Solar panels review, we have examined the performance, efficiency, and reliability of the company's solar panels. With their use of advanced technologies, high power output, and commitment to quality, JA Solar panels are an excellent choice for anyone seeking to invest in solar energy.
However, it is crucial to consider factors such as location, energy needs, and budget when selecting the right solar panels for your specific situation. To ensure you make the best decision, consult a professional solar installer and compare multiple brands and models before committing to a particular solar panel system.
