Why Are Solar Panels Black In Color

Solar panels are blue due to the type of silicon polycrystalline that is used for a certain set of solar panels.

Why are solar panels black in color.

The solar panels are blue in color because they are made using polycrystalline which is a type of silicon. While the monocrystalline and amorphous cells appear to be black a closer inspe. In the black colored mono crystalline solar panels the silicon is aligned in the same way forming the large single crystal of silicon. This article will dive into the different solar panel color and framing options available to homeowners and the pros and cons of each setup.

Technically the color black is known to absorb the highest amount of light. These solar skins do not fundamentally change the color of your solar panels but they do offer a solution for consumers that are looking for something outside of the traditional blue or black color. The blue color has an anti reflective property which increases the absorbing capacity and efficiency of the solar panel. Why solar panels are blue or black in color.

The silicon used to make the black panels have a very high purity although the alignment of the silicon is similar to that present in a polycrystalline. Here s a comparison of the three primary types of silicon pv cell. Consequently most solar panels have a blue hue to them. This is why most people will recall an image of several blue rectangular panels on hearing the word solar.

The blue color is largely due to an anti reflective coating that helps improve the absorbing capacity and efficiency of the solar panels. So the gaps between solar cells on a panel with a black backsheet will absorb heat instead of reflecting it. The raw silicon is melted and poured into a mold. You ll note that the polycrystalline cells which are very common are decidedly blue.

Black solar panels are monocrystalline solar panels and are created from the highest quality silicon. Their patent pending technology allows you to change to look of your solar panels to anything you want. This blog post explains why some solar panels are black and some are blue and the difference between the two. Yet most solar panels are blue in color since polycrystalline panels make up the majority.

We will see these things in the following paragraphs. Sistine solar skins are a relatively new technology coming out of an mit startup. A material that is relatively cheap to produce and efficient at generating an electrical charge. A black backsheet is a bad choice from the point of view of efficiency because the hotter solar panels get the worse they perform and in sunlight black gets hotter than white.
