Why Solar Panels Are Blue In Colour

The silicon is generally used in making the solar panels.

Why solar panels are blue in colour.

The blue color has an anti reflective property which increases the absorbing capacity and efficiency of the solar panel. The most efficient solar panel should be black absorbing nearly all the ligh. However most solar panels are blue in color since polycrystalline panels comprise the majority. Because they are not best panels.

The raw silicon is melted and poured into a mold. Solar panels are blue due to the type of silicon polycrystalline that is used for a certain set of solar panels. So you re stuck with the colour of the raw materials. Some technologies are better at transmitting sunlight through the colored layers than others.

Below we explain the colours of solar panels and whether they re due to change. The color of a solar panel is largely based on the way in which the solar module is manufactured. Consequences of colored solar panels. Yet most solar panels are blue in color since polycrystalline panels make up the majority.

The blue color is largely due to an anti reflective coating that helps improve the absorbing capacity and efficiency of the solar panels. There are two kinds of the solar panels. Blue solar panels are very common for several reasons but they are not the only color that a solar panel may come in. When we add color to a solar panel it becomes less efficient by definition.

It is a non metallic element with properties of absorbing most of the visible light and produce electricity. We will see these things in the following paragraphs. Raw materials and coatings. This is why most people will recall an image of several blue rectangular panels on hearing the word solar.

The anti reflection technology used now normally absorb light most at wavelength about 550 700nm letting blue lights reflected most. The science of solar is such that the blackest materials soak up the most sunlight and are therefore best for generating photovoltaic energy. The solar panels are blue in color because they are made using polycrystalline which is a type of silicon. Monocrystalline and polycrystalline solar panels are the two main forms of consumer solar panels and vary in color from either.

Why solar panels are blue or black in color. It s obvious but you can t paint your solar panels to match your roof the coating would severely block sunlight. But why has blue been the common colour for the technology.
