We offer Solar Panels made by all the leading manufacturers in China, including Suntech, Trina, Yingli, CSI, CEEG, Best Solar, Polar, etc.
There are three main types of solar panels: Monocrystalline, Polycrystalline, and Thin Film or amorphous. Monocrystalline panels have uniform dark gray cells and have the highest output per cell area and tend to be the most expensive. Polycrystalline cells look somewhat like shattered glass and tend to be less expensive and only slightly less efficient per cell area. These cells are usually square and result in a slightly smaller solar panel than solar panels constructed using the more efficient Monocrystalline which tend to be rounder. Monocrystalline and Polycrysalline solar panels are rigid and have a glass cover. Thin Film type panels are made by depositing the active silicon on either a stainless plate or a flexible backing. They have recently become very popular, because unlike the other types, their output does not decrease in elevated temperatures. Indeed, one independent test showed a slight increase in output. This means that the actual output is likely to be close to the nameplate rating.Their conversion efficiency of sunlight to electricity is 6.3%, about half that of polycrystalline or Monocrystalline panels. Thus an array of amorphous panels will require about twice as much roof space as an array with a similar rating using other types of panels. This can limit their application when the amount of unobstructed roof space is limited.
