Theory
Solar panels are divided into mono-crystalline silicon and poly crystalline silicon. What are the main differences between them? Cost and conversion efficiency are different. Poly crystalline silicon technology and mono-crystalline silicon technology are very mature, but mono-crystalline silicon has higher conversion efficiency, small volume and high cost, while poly crystalline silicon has large volume and lower conversion efficiency than mono-crystalline silicon, but the cost is more economical.
