Proven Efficiency

The 5-busbar polycrystalline cell design achieves a module efficiency of 17.2% and a rated output of 340W under STC. The positive-only power tolerance of 0 to 5W means each module delivers at least its rated power.

Temperature Performance

With a Pmax temperature coefficient of -0.400%/°C, a Voc coefficient of -0.330%/°C, and an Isc coefficient of 0.058%/°C, the module maintains stable output across a wide range of conditions. Its nominal operating cell temperature (NOCT) is 45±2°C, and it operates from -40°C to 85°C (-40°F to 185°F).

Quality and Reliability

JA Solar manufactures this series under ISO 9001:2015, ISO 14001:2015, and OHSAS 18001:2007 management systems. The module also meets IEC TS 62941:2016 guidelines for PV module design qualification. Built-in anti-PID performance helps protect against potential-induced degradation over the module's lifetime.

Long-Term Power Warranty

The module is backed by a 12-year product warranty and a 25-year linear power output warranty. Under JA Solar's linear warranty, output is guaranteed at 97.5% in the first year, declining linearly to 80% at year 25.

Durable Frame and Weather Resistance

The 40mm frame is rated for static loads of up to 5400Pa on the front and 2400Pa on the back. For NexTracker installations, it is rated at 2400Pa front and back. The IP67 junction box with 3 bypass diodes protects against dust and water ingress and reduces power loss from partial shading. It is rated Application Class A.
