JA Solar Certification: New PV Module Safety Standards

There is some new news from JA Solar worth sharing.

The latest JA Solar certification covers two new mandatory national standards in China: GB 47739-2026 and GB 47740-2026. The certification includes its DeepBlue 4.0 Pro and DeepBlue 5.0 module series.

It’s an interesting development, especially as product safety and quality are getting more attention across the solar industry.

What Are the New PV Module Standards?

Both standards were published in May 2026 and will officially take effect on June 1, 2027.

They focus on two different aspects of solar modules.

GB 47739-2026 – PV Module Safety Requirements

This standard covers electrical safety, mechanical loads, fire safety and hazardous substances. In simple terms, it sets clearer safety requirements for PV modules.

GB 47740-2026 – PV Module Nameplate Labeling Requirements

This one focuses on product labeling and technical information, including rated power, current and voltage. It also aims to improve the accuracy of product information and traceability.

These details may look small, but they matter when modules are manufactured, shipped and installed in large quantities.

What Makes JA Solar Certification Worth Noticing?

One detail worth mentioning is that the certification involved more than laboratory testing.

The process included three stages:

• Type testing
• Initial factory inspection
• Post-certification supervision

So the assessment looked not only at the modules themselves, but also at the factory’s ability to maintain quality during mass production.

For large solar projects, this is important. When thousands of modules are delivered to one site, consistency across the shipment matters just as much as the rated power on the datasheet.

Of course, these Chinese national standards do not replace IEC, TÜV, UL or other certification requirements in overseas markets. Buyers should always check the requirements of their specific projects.

A Small Update from JA Solar

The solar industry has spent years focusing on higher efficiency, more power and lower prices. These things still matter, but product safety and manufacturing quality deserve attention too.

As someone working with JA Solar products at Joinsun, I find updates like this worth following. They give us a better understanding of what is changing behind the products we discuss with customers every day.

For me, it’s always good to see manufacturers paying attention to the details beyond module wattage. Those details matter when a product is expected to work reliably for many years.

We’ll keep following JA Solar’s product and technology developments and sharing updates that are useful to the solar industry.
