The serial number has 16 digits. The 1st and the 2nd digits are the year code, and the 3th is the month code (A, B, C stands for October, November and December respectively). For example, 121PXXXXXXXXXXXX means the module was assembled and tested in the January of 2012. Each module has only one bar code.
JA Solar Modules are designed to meet the requirements of IEC 61215:2016 and IEC 61730:2016, application class A. Modules rated for use in this application class may be used in system operating at greater than 50V DC or 240W, where general contact access is anticipated.
To ensure a set of industry standard performance numbers, solar panels are tested under specific conditions. That’s the (STC) bit, or Standard Testing Conditions or Criteria. There are many factors that impact solar panel efficiency. Temperature, wind, aspect, load, elevation, to name just a few, and they’re all variable.

6 FAQs about [How to read the A number of JA Solar panels]
What is the difference between JA Solar and standard solar panels?
JA Solar’s standard solar modules also come in a 60-cell or 72-cell count. Here is a table to outline the differences in power output and efficiency for these modules: Outside of power output and efficiency, there are a few other features that differentiate these solar modules. JA Solar’s standard panels have limited power degradation.
How efficient are JA Solar panels?
From the above tables, you can see that the power output and efficiency of JA Solar’s modules are very comparable with the majority of other solar panels on the market. It is very common to see panels around 15-16% efficiency on the low end and 18-19% on the high end, although some solar panels can reach an efficiency of over 21%.
What types of solar panels does JA Solar offer?
The final category of solar panel modules that JA Solar has to offer are the Bifacial Mono PERC Double Glass modules. There are also 4 options within this category — two 60-cell options and two 72-cell options. Front and Back of JA Solar’s Bifacial Modules
What are the electrical parameters used in JA Solar modules?
For the detailed electrical parameter, see the below list: The junction boxes used with JA Solar Modules contain bypass diodes wired in parallel with the PV cell strings. In the case of partial shading, the diodes bypass the current generated by the non-shaded cells, thereby limiting Modules heating and performance losses.
Can JA Solar make changes to the product specifications or installation manual?
JA Solar reserves the right to make changes to the product, specifications or installation manual without prior notice. Failure to comply with the requirements listed in this manual will invalidate the Limited Warranty for Modules as provided by JA Solar at the same time of sale to the direct customer.
