Lesson 2: Types of Solar Panels

Learn the difference between Monocrystalline, Polycrystalline, and Thin-Film panels to choose the right tech for your roof.

Monocrystalline Panels

Monocrystalline panels are made from a single, continuous crystal structure. They are highly efficient and space-efficient, making them the best choice for residential roofs where space is limited. They are easily recognizable by their sleek, black appearance.

Polycrystalline Panels

Polycrystalline panels are made from silicon fragments melted together. While slightly less efficient than monocrystalline panels, they are more affordable and have a lower environmental impact during manufacturing. They have a distinctive blue, speckled look.

Bifacial Panels

Bifacial solar panels can capture sunlight from both the front and the back of the panel. They are particularly effective when installed on highly reflective surfaces (like white commercial roofs or ground mounts) because they can generate additional power from reflected light (albedo).
