The efficiency of polycrystalline solar panels is somewhat lower, but the benefit for customers is
that this option is more affordable. In addition, when you seek polycrystalline solar panels for sale,
the sellers may highlight the blue hue of these panels compared to the monocrystalline panels’ black hue.
Although polycrystalline solar panels are also composed of silicon, it does not involve the use of single-crystal silicon. Polycrystalline solar panel manufacturers melt multiple silicon fragments together to produce the wafers for these panels. For this reason, they are called “poly” or multi crystalline. The electrons in each cell will have less space to move because of many crystals in a cell. Therefore, the efficiency ratings of polycrystalline solar panels are relatively lower.
