Here are a few technical details: 

  • The JAM54D40 modules have highly efficient mono PERC cells with multi-busbar technology (MBB). This optimizes the power output while minimizing the internal resistance loss. 
  • The half-cell configuration ensures that less power is lost and the modules work better even in the shade. This makes them particularly suitable for difficult installations.
  • The module has an advanced cell architecture that works really well in low light conditions.
  • It also has a high efficiency at different temperatures. Note that the lower the Temp. Coefficiency Factor, the better the performance of the modules in full sun (higher temperatures).
  • The positive power tolerance of 0/+5 W ensures that the modules consistently deliver enough power to meet or even exceed the rated values.

Installation and compatibility

These modules work with the most common inverter brands and mounting systems. The aluminum frame is robust and can be used for various mounting configurations. The junction box is IP68 certified and the connectors are high quality, so they work reliably even when the going gets tough.

JA Solar D40 Series - Ideal for the following applications:

Commercial rooftop systems (Commercial), Residential solar systems (Residential), Ground mounted systems (Commercial/Industrial), Carport structures (Residential/Commercial)
