JA Solar launches 800 W solar panel


The 14th SNEC photovoltaic exhibition and conference held in Shanghai this week set the stage for the presentation of the most powerful solar panels on the global PV market. The Chinese pv magazine team was there and has reviewed all of them.

JA Solar

Chinese manufacturer JA Solar unveiled what is thus far the world’s biggest and most powerful panel with an 810 W model. Called Jumbo, the panel has quadruple layouts of 47 cells and dimensions of 2,220 by 1,757mm. This panel utilizes a triple-cut cell design with 11 busbars on 210mm wafers. JA puts the maximum power output at 800 W. The module is not yet in mass production.

JA Solar launched a new 525 W+ panel in May.


China’s largest cell manufacturer, Tongwei, unveiled its G12 module series with a power output ranging from 760 to 780 W. The series is also based on a 210mm wafer and multi-busbar (MBB) technology. Measuring 2,357mm by 1,612mm, it weighs 39kg. With MBB technology, Tongwei said the panel would reduce BOS and LCOE for investors and operators. The G12 series is likewise not yet in mass production.


Trina Solar presented a 660 W version of the Devex module. Trina said the new product had the same features and specifications as the Vertex 600 W panels it launched in mid-July, but with systematic optimization. The panel is based on 210mm wafers, MBB technology and high-density interconnection.

Trina last month formed the 600 W+ Photovoltaic Open Innovation Ecological Alliance with the aim of producing the next level of ultra-powerful modules.

  1. What is the big deal about a “Big Panel”…. mine is bigger than yours… who defines what is a Panel?
    Suppose I provide a 40ftx8ft PV Panel…. (maybe even 12ft…. limited by Container Size)… a whopping 5-7KW… will my Panel, BECAUSE I CALL IT SUCH, become the biggest…. more than 10 times larger than the next best…. O my… what a beast..!!!
    What Solar “Systems” need is Optimum Value (Lowest SYSTEM COST/Max. Performance, O&M & LIFE…)…
    My 8ftX40ft Panel beats ANY HANDS DOWN IN SIZE… but could lose on all other counts… would this “Panel” REALLY be a “Breakthrough”…????
