July 23, 2013JA Solar sells its products to solar manufacturers worldwide, who assemble and integrate solar cells into modules. The company has 
two solar cell manufacturing facilities, one located in Ningjin, Hebei Province and the other in Yangzhou, Jiangsu Province. JA Solar sells solar panels as an OEM Solar Panel Producer which means that it sells its solar panels to companies who put their own brand names on solar panels produced by JA Solar.
Yingli Green Energy (YGE) is one of the oldest Chinese companies and is completely integrated. One of the world’s first fully vertically integrated photovoltaic manufacturers, the company develops, manufactures and sells high-quality modules under the brand Yingli Solar to a wide range of markets including Germany, Spain, Italy, Greece, France, South Korea, China, and the United States. The company is headquartered in Baoding, China with over 11,000 employees worldwide & more than 10 branch offices globally. The business model covers the entire PV value chain, from polysilicon production to the assembly of modules.
Both Yingli Green Energy (YGE) and JA Solar (JASO) Modules are good buys and one of our top picks to buy in 2013. Both Yingli Green and JA Solar are Chinese companies and provide modules at cheap prices.
Distinguishing Features between JA Solar and Yingli Solar Modules
Classification of Solar Modules and Available Models
Yingli Solar panels are divided into: 1) Monocrystalline: PANDA 48 and 60 cell series 2) Multicrystalline: YGE 48, 60 and 72 cell series and iii) Off-grid modules: YLSYS 300, 800, 1200 and 1600 series.
