About Us

  Sumai International Trade (Shanghai) Co.,Ltd specialized in the portable solar products. But we are special enough for our products are made from A-si module, flexible solar panel.
  
  We adopt triple-junction technology; this makes our flexible solar products unique. It can not only absorb the red light just as the crystalline module and other thin film module, but also the blue light and green light, so the actual performance will be much better than the traditional ones. And because of its special structure, it has the low tolerance, so it will not influence its performance when it is dirtied. This can not been gotten by other modules.
  Just as we know, when the temperature arises, the output of the battery will go down, but this will not happen to our products, this is other advantage.
  
  There are still some benefits of TP-solar, which is our brand, please keep attention to it, you may find what you really want.
