The video, presented by Amy from the altE Store, explains the differences between monocrystalline and polycrystalline solar panels. Monocrystalline panels are made from a conical silicon ingot, resulting in a consistent dark color and higher efficiency, but at a higher cost. Polycrystalline panels are made from a square mold, leading to less waste and lower costs, but slightly lower efficiency. The video compares their performance, noting that monocrystalline panels handle heat better and perform slightly better in low light. However, advances in technology have minimized these differences, making the choice between them often a matter of color preference or space constraints.
