4 FAQs about What is the blue light on photovoltaic panels

Why are solar panels blue?

Solar panels are blue due to the type of silicon (polycrystalline) used for certain solar panels. The blue color is mainly due to an anti-reflective coating that helps improve the absorbing capacity and efficiency of the solar panels. Black solar panels (monocrystalline) are often more efficient as black surfaces more naturally absorb light.

What is the difference between blue and black solar panels?

Blue solar panels are made of polycrystalline solar cells, while black panels are comprised of monocrystalline cells. Why trust EnergySage? Most solar panels have a blue hue, although some panels are black. The source of this color difference comes from how light interacts with two types of solar panels: monocrystalline and polycrystalline.

Why are polycrystalline solar panels blue or purple?

The anti-reflective coatings commonly used on polycrystalline solar panels are designed to enhance light absorption by minimizing reflections. These coatings often have a blue or purple hue due to their specific chemical composition and the way they interact with light.

Are blue solar panels better than polycrystalline panels?

Blue Panels are Less Efficient: While monocrystalline panels are generally more efficient, polycrystalline panels are still highly effective and suitable for many installations. Color Affects Performance: The performance of solar panels is more influenced by their material quality, manufacturing process, and coatings than by their color.
