Monocrystalline vs Polycrystalline Solar Panels

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.

What is the main visual difference between monocrystalline and polycrystalline solar panels?

• Both types of panels look identical.

• Monocrystalline panels have a mottled look, while polycrystalline panels are consistent in color.

• Monocrystalline panels are black or dark blue, while polycrystalline panels have a blue mottled look.

• Monocrystalline panels are blue and polycrystalline panels are black.

How are monocrystalline solar panels manufactured?

• By melting silicon rocks into a square mold.

• By cutting wafers from a conical silicon ingot.
