Navigating the world of solar energy can feel like you're lost in a maze, right? With so many manufacturers on the market, finding the one that best suits your needs can be quite the challenge. JA Solar is one of the names you might have come across in your search. You've probably seen them mentioned in discussions about high volume production and affordability, but what does that really mean for you?

Let's start by acknowledging that JA Solar is indeed a significant player in the solar PV industry. This isn't a small achievement considering the competitiveness of the market. 

It's evident they're doing something right.

One thing that really stands out about JA Solar is their commitment to their customers. You'll notice this when you look at their warranties, their continued strive for innovation and that they’ve been around for a long time.

But there is something that seems insignificant to others, but is vital to us.

They guarantee stock for us.

This is not a trivial commitment, and it shows that this is a brand we can rely on. 

Also, you can take a look at our Solar Panel Tier List. JA Solar is right at the sweet spot. It is not as expensive as the most premium brands, but still offer great value at a decent price. 

Some of the best product and performance warranty

JA Solar has consistently demonstrated its commitment to quality and performance. In an older warranty notice from 2018, JA Solar provided product warranties that were in line with industry standards at the time. 

However, as the solar industry evolved and technology improved, JA Solar took a significant step forward. They now offer an impressive 25-year product warranty and a 25-year performance warranty, ensuring that their solar panels are free from defects and will maintain a certain level of efficiency over time.

To find out more about the difference, here’s an article we wrote earlier about the different types of solar panel warranties.

This move aligns with the industry's shift towards longer warranty periods, reflecting the confidence manufacturers have in their products. A recent article on gosunny.com.au emphasizes the importance of solar panel warranties, highlighting that they are a testament to the product's quality and longevity. 

For consumers, warranties are a crucial consideration. Panels with a warranty period of less than 20 years might not offer the same peace of mind or value for money. 

With JA Solar's enhanced warranty, consumers can be assured of a product that stands the test of time.

One of the largest mono-crystalline solar panel manufacturers in the world

As one of the world's foremost manufacturers of mono-crystalline solar panels, JA Solar has mastered the art of producing high-quality panels at scale. This mass production not only helps keep solar panels more accessible price-wise but also maintains consistent quality across all their products.

JA Solar offers a range of solar panels, each designed to cater to different needs. However, their focus on mono-crystalline technology remains constant across all models. This specialization has transformed JA Solar into a leading authority on mono-crystalline solar panels, continually innovating and seeking ways to enhance their efficiency.

The fruits of their dedicated research and development are evident in their impressive achievements, such as the production of a 615 W solar panel and reaching remarkable production efficiency milestones. This continuous innovation guarantees that when you invest in a solar panel from JA Solar, you're receiving a product backed by some of the most advanced mono-crystalline technology available today.

Mono-crystalline solar panels are renowned for their efficiency and durability. Made from single-crystal structure silicon, they offer the highest efficiency rates because they allow electrons more room to move for a better flow of electricity. Their characteristic black hue and rounded edges distinguish them from other types of solar panels.

Other options include polycrystalline solar panels and thin-film solar panels. Polycrystalline panels, identifiable by their blue color, are made from multiple silicon fragments melted together, which reduces their efficiency compared to mono-crystalline panels. On the other hand, thin-film panels are lightweight and flexible but have lower efficiency, making them suitable for larger, less space-restricted installations.

JA Solar’s long term vision into their supply chain

JA Solar's strategic investment in their supply chain exhibits a robust long-term vision. This dedication to sustainable growth is a clear indication that JA Solar is not only a pioneer in the solar industry but is also committed to remaining a leader in the years to come.

By bolstering their supply chain, JA Solar ensures a steady and reliable flow of raw materials, crucial for maintaining their high production volumes. This reduces the risk of potential bottlenecks and ensures a consistent output, which can significantly increase the confidence of partners and investors alike.

Additionally, this investment indicates a lower risk for us in our partnership. With JA Solar continually reinforcing their manufacturing process, the probability of supply disruptions or quality issues diminishes considerably. This commitment can allow us to plan our projects with greater certainty, knowing that JA Solar’s products will be available and uphold the high standards we expect.

The investment also implies potential cost advantages. A robust supply chain often leads to economies of scale, enabling JA Solar to offer competitive pricing without compromising on the quality. This could translate into cost efficiencies for us, making solar installations more affordable and appealing to our customers, while also improving our profitability.

Have a good price-efficiency ratio

JA Solar panels often have high efficiency, such as the JAM54D41 GB models having at least 20% efficiency. These panels are also cheaper than other manufacturers, allowing you to purchase more panels without hurting your budget. That allows you to put more panels on your residence or cut down on project costs.

Some solar panels with 20% efficiency can be expensive due to the technology that goes into them. While JA Solar might not have the highest efficiency, their solar panels are some of the most affordable. That gives you a good price-efficiency ratio that allows you to power your residence.

Cost is a big factor when people consider getting solar. While efficient solar panels are important, you also want to avoid exceeding your budget. That makes JA Solar’s panels great for generating more power for your household and keeping costs down.

Dark panels look great on your rooftops

Even though solar panels only have one colour, you still want your residence to look great. Thanks to the black cell colour of JA Solar’s panels, you can enjoy a sleek look on your house. That’s better than other solar panels which are blue, since they don’t look as nice on a building. Both will still generate power, but black fits more paint choices.

Dark solar panels will also absorb more light than blue solar panels, helping you generate more energy as a result. Thanks to JA Solar’s efficient solar panels, that means more energy for your house. They also work better in hot weather since they absorb more sunlight. JA Solar’s panels also have good temperature ranges, and can function even on bright days during summertime.

Having dark solar panels makes your residence look better while working better during sunny days. JA Solar constantly works to make solar panels more efficient and ensure they work well in Australia’s temperatures. This means you have more design options available to you that generate power for your home.

The company has been around since 2008

One of the biggest concerns when it comes to buying a solar system is wondering if a company will still be around. Solar panels have warranties that extend at least a decade, which is a long time for things to go wrong. Companies can go bankrupt which means you won’t be able to get replacements if something goes wrong.

JA Solar has been a trusted name in the solar industry since 2008, and many solar installers use their products. They are still going strong in 2023, working on new international projects and pursuing more research. It’s unlikely that JA Solar is going to go out of business anytime soon with that level of success.

While you can never predict the future, it’s unlikely that any warranties for JA Solar products won’t be honoured. If something goes wrong, you can trust that JA Solar will replace your panels and ensure they work perfectly. They have a good track record of success and lots of business for their solar panels to keep them around.

There will always be panels available

A big concern with solar panels is not having replacements on hand if something goes wrong. Even if a solar panel is covered by warranty, it doesn’t mean much if the panel can’t be replaced. If new solar panels can’t be delivered, that also means setting up new solar systems isn’t possible. That could drag out timeframes or increase costs to solar systems, which aren’t desirable outcomes.

Fortunately, JA Solar is one of the largest manufacturers of solar panels in the world. They are known for their volume and have maintained that reputation for years. It’s very unlikely that they would ever run out of solar panels, and they are constantly acquiring materials to make more. Their experiments to improve solar panels also require resources, which they have no trouble obtaining.

If you are concerned that your solar panels won’t arrive, try talking with solar installers who use JA Solar’s panels. Your orders will arrive and you won’t have to worry about getting the amount required. It’s also not as costly to order as many panels as it would be with other companies, helping you stay within budget.


JA Solar’s panels are some of the best in the industry. The company is known for their manufacturing volume and constant improvements in technology. Their black panel design looks great on houses and can withstand the harsh Australian summer. It’s also great for absorbing more sunlight and converting that into energy.

If you have any questions about JA Solar’s panels, talk to our team today. We know that solar is a big investment and you have a lot of questions. You also want to get the best solar system for the lowest cost. JA Solar’s panels can certainly help you do that, and we’ve installed several of their panels on homes across SA.
