Solar colored light power generation panel

What color are solar panels?

The most common color for solar panels is black, as black surfaces are excellent at absorbing a wide range of wavelengths from the visible light spectrum. This is why the majority of solar panels on the market have a dark, black appearance. There are two main types of solar panel technologies that contribute to this black color:

How do colored solar panels work?

With colored solar panels, scientists have to consider a sort of “visible” light spectrum for the panels in the same way our eyes absorb or reflect different wavelengths of light. Generally speaking, the more transparent the top layers of the solar panel cell (such as the front glass and the encapsulant), the more light the silicon can absorb.

What affects the color of solar panels?

Something else that impacts the color of solar panels is the thickness of the anti-reflection coating applied to each panel. This thin film deters light from reflecting off the panel’s glass and instead helps it absorb into the panel and produce more solar energy.

Will changing the color of solar panels reduce energy production?

However, as solar panels have become more popular and the market has expanded, more consumer demand for other colors appeals to building aesthetics. Initially, researchers and scientists thought changing the color of solar panel cells would amount to a 40% to 50% reduction in energy production.

Are black colored solar panels a good choice?

Although black colored PVs maximize energy generation by harvesting a broad range of solar light, their monotonous color limits their installation in urban areas and portable devices where the harmonization of color with neighboring exterior elements is a high priority.

Why do solar panels look red?

Solar panels are typically a deep black color because their job is to absorb light, whereas a red car looks red because the finish reflects red light instead of absorbing it. Most attempts to give these devices color, then, will decrease their ability to absorb light and generate power.
