JA Solar Holdings is based in Shanghai, China, and it manufactures solar panels and a variety of solar-related materials for residential and commercial applications. JA Solar is considered a budget brand, but among the different affordable panel manufacturers, JA Solar delivers relatively high quality and high efficiency ratings for boosted performance and savings.
Overall, JA Solar makes great panels for homeowners on a budget. The price per watt is considerably lower than you''d find from most other manufacturers, but among other affordable brands, the efficiency rating and performance specifications are above-average. For the cost, JA panels deliver outstanding value.
With that being said, we more commonly recommend higher-quality, higher-efficiency brands, like REC, Maxeon, Trina and QCells. These other brands usually have superior warranty coverage and better durability, so they will save you more in energy costs in the long run in many cases.
In the following sections, we''ll take a look at each solar panel option JA Solar manufactures and explain which we recommend for different applications. The company manufactures two lines of panels — DeepBlue 3.0 and DeepBlue 4.0x — and we''ll discuss the individual products within each line below.
The DeepBlue 3.0 product line from JA Solar is the more affordable of the two, meaning it''s the best option if you''re looking to keep your installation prices as low as possible. This line of products includes three distinctive subcategories: DeepBlue 3.0 Light, DeepBlue 3.0 and DeepBlue 3.0 Pro.
The DeepBlue 3.0 Light line of panels from JA Solar are the smallest panels of the bunch and have the lowest wattage per panel, coming in between 380 and 415 watts. Generally speaking, JA Solar panels are larger than the average panels available from other manufacturers, but this product line is in line with the average.
These panels only come with a 12-year product warranty and a 25-year production warranty.
The DeepBlue 3.0 panel lineup is meant for homeowners who aren''t necessarily looking to keep costs as low as possible and instead want to ensure their system performs better and produces more energy.
Overall, we''d recommend this line of panels over the 3.0 Light panels, as higher efficiency ratings and power outputs mean you might be able to get away with fewer panels on your roof. Additionally, higher-efficiency panels mean more production, which could mean greater energy savings over the life of your system.
Like the 3.0 Light line of panels, these also only come with a 12-year product warranty, which is well below the industry standard. However, the production warranty is still quite good, as it lasts for 25 to 30 years, depending on the specific model you have installed.
As you might imagine, the DeepBlue 3.0 Pro series is the highest-performing one in the 3.0 product lineup. They have the highest efficiency ratings, come with the largest wattages and usually boast a 30-year production warranty. However, these still only come with a 12-year equipment warranty.
The DeepBlue 4.0x line of panels from JA Solar boasts higher efficiency ratings than the 3.0 series, and they also all come with the superior 30-year production warranty, which is longer than the coverage for many of the 3.0 panels.
The 4.0 series is going to be a better option overall if you''re looking for maximized efficiency and energy savings, although they do come at a higher price per watt, on average.
We''ll include some information about the DeepBlue 4.0x products below.
JA Solar uses mostly monocrystalline solar panels and half-cut cells, which are more durable, reliable and efficient than polycrystalline (poly) solar panels. Most models also include multi busbars (MBB) to reduce the risk of hotspots and improve overall performance. These are common in many brands, though.
There isn''t much in the way of proprietary clean energy or solar cell technology used in JA Solar panels other than its polycrystalline PERC cells or PERCIUM cells, but it does use a variety of technological advancements to push the performance of its products.
We''ll discuss some of the renewable energy technology JA commonly uses in its solar modules in the following sections.
PERCIUM cells were created by JA Solar; as per the company, they are the first poly cells to surpass the 20% efficiency rating mark, which is pretty impressive.
Polycrystalline cells are made by compressing shards of silicone together rather than cutting the cell from a single silicon wafer, as you''d see in monocrystalline solar cells. Mono PERC cells come with a higher average efficiency rating and superior durability, so they''re generally preferred for home solar systems.
However, the PERCIUM cells keep manufacturing costs low — one of the benefits of poly panels — but help maximize the efficiency rating. The durability is still lower than mono cells — hence the 12-year equipment warranty from JA — but the efficiency is comparable. That means lower installation costs and similar energy savings over time.
Gapless ribbon technology is tech used by many solar companies. It involves using connective ribbons to string solar cells together so that they overlap on the edges. This eliminates wasted space as compared to when the non-conductive edges of cells are normally soldered together.
Gapless tech also generally improves panel durability since the soldering isn''t rigid. The flexibility of the ribbon allows for some movement before the connection is lost, leading to fewer issues with solar cells failing to produce and a lower risk of losing out on solar savings.
Bifacial solar panels may not have a higher efficiency rating than single-face panels, but they tend to collect more power for your home, making them a great option for residential use. Ultimately, that can translate to needing fewer panels on your roof and saving more money over time.
JA Solar panels have temperature coefficients that fall between -0.3% and -0.35%. The temperature coefficient of a panel tells you how much of the starting efficiency the panel loses per degree above 25 degrees (C) or 77 degrees (F). The lower the temperature coefficient, the more efficiency your panels will maintain as the temperature goes up.
The average temperature coefficient for tier-one solar panels is -0.35%. That means all JA panels are either average or above average in terms of efficiency loss in warmer temperatures.
Since JA panels also have above-average efficiency ratings to begin with, that means they will not only outperform most competitors at lower temperatures but also maintain more of their efficiency as they get hotter.
This makes them a great option in just about any climate, although you might want to choose a panel with a temperature coefficient that''s well below average — like Maxeon and Panasonic panels — if you live in a very hot climate.
