What are Poly-crystalline solar panels?

Poly-crystalline solar panels are a close cousin to mono-crystalline differing only in the way they are manufactured, in a cast rather than individual crystal ingots.

These panels are blue in colour and share all the same technical aspects as mono-crystalline modules such as heat tolerance and shading.

Poly-crystalline solar panels have a slightly lower efficiency per watt than the mono-crystalline modules but they have a slightly better yield.
