JA Solar Company Overview:

Headquartered in Shanghai, JA Solar employs almost 30,000 people and had a turnover for the first three-quarters of 2022 amounting to £5.7 billion. The company ploughs a significant part of this revenue back into its own research and development. This shows in its constant updating of products and release of new solar ranges with improved performance and higher efficiency solar panels.

The company has 12 manufacturing plants situated around South East Asia, although the majority are in China. JA Solar has received worldwide praise and awards for its solar products.

JA Solar produces an extensive range of panels for most uses, from residential, to commercial, industrial and utility-scale solar energy systems. The first solar panel the company built using P-type PERC cells in the larger 182mm format was the Deep Blue 3.0 series. This very-successful design implemented many of the latest cell technologies, including multi-busbars in a high-density half-cell format.

Their latest Deep Blue 4.0X series, launched in May 2022, utilises solar cells made using the higher performance N-type silicon substrate which is one of their high efficiency solar panels and claimed to have an efficiency of up to 24.8%.

Deep Blue 3.0 – Current range using P-type PERC cells
Deep Blue 3.0 Light – Compact residential series up to 420W
Deep Blue 3.0 Pro – High power commercial series up to 605W
Deep Blue 4.0 X – Next generation N-Type panels featuring high efficiency

Summary

JA Solar panels are well-regarded and good affordable monocrystalline solar panels.

The average efficiency is 20%-21% which puts JA panels among the most efficient in this price bracket.

Their most efficient panels are the n-type PV module DeepBlue 4.0 X with an efficiency rate of 24.8%.

JA Solar panels are very durable, wind resistant and offer good shading tolerance.

The warranties are industry standard with product warranties of at least 12 years.

The design is somewhat run-of-the-mill, but agreeable for its purpose.

JA Solar offers panels up to 555 watts and also has bifacial modules for sale. That makes this brand particularly appealing to customers who are looking to build solar installations of a larger scale, or even for commercial solar projects, rather than simple residential use.

Overall, JA solar modules are a good, reliable choice for customers who have a budget to keep to, but who want decent performance and value for money. While they are not premium solar modules, or even considered mid-range solar panels, they nonetheless are reliable and affordable panels and a good option for your next solar energy project.
