The process used to make polycrystalline solar panel is simpler and cost less. The amount of waste silicon is less compared to monocrystalline.
Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. This technically means that they perform slightly worse than monocrystalline solar panels in high temperatures. Heat can affect the performance of solar panels and shorten their lifespans. However, this effect is minor, and most homeowners do not need to take it into account.

Polycrystalline solar panels are made up of multiple crystals. Instead of going through the slow and very expensive process of creating a single crystal, manufacturers simply put a crystal seed in a cast of molten silicon and allow it to cool. Due to this casting method, the crystal surrounding the seed isn’t uniform and grows into multiple small crystals.
