Remember the following. SSOL gets their panels directly from China.
"The reason that's of concern is that Chinese polysilicon modules are higher efficiency, meaning installers can pack more power into less space and save costs on installation costs. Trina Solar's (NYSE: TSL ) multicrystalline panels range from 14.3% conversion efficiency to 16% and Yingli Green Energy's (NYSE: YGE ) are 14.4%-15.6% efficient. That compares to 13% average conversion efficiency for First Solar; monocrystalline panels are even more efficient. "
