4 FAQs about What is the blue and black color of photovoltaic panels

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 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.

Why are black solar panels more expensive than blue solar panels?

It makes blue solar panels less expensive, but it also means blue panels are less efficient. Black solar panels absorb light and generate electricity more efficiently than blue solar panels. Since you need fewer panels to generate the same amount of electricity, black panels are usually less expensive in the long run and use less roof space.

Why are blue solar panels more expensive than monocrystalline solar panels?

The multiple crystals in the formation process create less silicon waste and require less energy than the monocrystalline process. It makes blue solar panels less expensive, but it also means blue panels are less efficient. Black solar panels absorb light and generate electricity more efficiently than blue solar panels.
