The JA Solar JAM66D45 600W panel is a high-efficiency bifacial double glass module using advanced n-type monocrystalline cells. Designed for superior performance and longevity, it offers a maximum power output of 600W and module efficiency of 22.2% under standard test conditions. Its robust build, low degradation rate, and bifacial technology ensure strong returns over its 30-year performance warranty.
Assembled with 11BB PERC cells, the half-cell configuration of the modules offers the advantages of higher power output, better temperature-dependent performance, reduced shading effect on the energy generation, lower risk of hot spot, as well as enhanced tolerance for mechanical loading.
More benefits of this module range
- Higher power output.
- Less shading and lower resistive loss.
- Lower LCOE
- Better mechanical loading tolerance.
- 12 Year Product Warranty and 30 Year Linear Output Warranty.
