JA Solar Panel

JA Solar, established in 2005, is a leading manufacturer in photovoltaic products. With 12 manufacturing bases and over 20 branches worldwide, business covers silicon wafers, cells, modules and photovoltaic power stations. JA Solar products are available for all kinds of solar system installations.

Multi-busbar Technology

Assembled with multi-busbar PERC cells, the half-cell configuration of the modules offers higher power output, better temperature-dependent performance, less shading and lower resistive loss, as well as enhanced tolerance for mechanical loading.

JA Authority Certificate

Sunpal Solar cooperate with JA since 2010. With continuous technological innovation, good financial performance and a comprehensive global sales and service network, JA Solar has won unanimous praise and high recognition from customers at home and abroad.

JA solar panel featureas:

• Positive power tolerance (0~+5W) guaranteed High module conversion efficiency (up to 20.8%) 
• Slower power degradation enabled by Low LID Mono PERC technology: first year <2%, 0.55% year 2-25 
• Solid PID resistance ensured by solar cell process optimization and careful module BOM selection 
• Reduced resistive loss with lower operating current
• Higher energy yield with lower operating temperature
• Reduced hot spot risk with optimized electrical design and lower operating current
