Why Are Solar Panels Dark Coloured

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 dark coloured.

Yet most solar panels are blue in color since polycrystalline panels make up the majority. Some of these look rather black but most of them are blue. Technically the color black is known to absorb the highest amount of light. Some of the energy is also converted into heat energy as is natural.

As far as i know solar panels work by absorbing light energy and then converting this to electrical energy. Here s a comparison of the three primary types of silicon pv cell. You ll note that the polycrystalline cells which are very common are decidedly blue. However if your preference is aesthetics more than the efficiency then colored or photo printed panels are an exciting trend to investigate.

The blue color is largely due to an anti reflective coating that helps improve the. Colored solar is pioneering colored solar energy solutions that efficiently captures sunlight and converts it to electricity just like conventional systems while also addressing the needs of many applications for architectural sensitivity and beautiful aesthetics colored solar is a manufacturer and systems integrator of solar electric systems and is leading the development testing. When we add color to a solar panel it becomes less efficient by definition. The science of solar is such that the blackest materials soak up the most sunlight and are therefore best for generating photovoltaic energy.

Their patent pending technology allows you to change to look of your solar panels to anything you want. This is why most people will recall an image of several blue rectangular panels on hearing the word solar. While the monocrystalline and amorphous cells appear to be black a closer inspe. Sistine solar skins are a relatively new technology coming out of an mit startup.

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. Some technologies are better at transmitting sunlight through the colored layers than others. In this article we will examine what the color of a solar panel can tell you and what makes solar panels blue. As technology advances the color of solar panels may change towards black in favor of greater efficiency as mono crystalline prices continue to fall.
