With the rise of renewable energy, solar energy has attracted much attention as a clean and sustainable form of energy. Traditional blue solar panels are functional but somewhat drab in appearance. In recent years, however, black solar panels have been a popular mainstream product in Europe, especially the Nordics. Do you know why?

Before discussing this reason, we must first clarify the difference between monocrystalline and polysilicon panels:
Polycrystalline panels are less efficient because some crystals form during the manufacturing process. These crystals make it harder for electrons to flow through the cell. On the other hand, the lack of crystal formation in mono PERC panels allows electrons to flow easily, making these panels more efficient. Because they are more efficient, they are also more expensive. Also, monocrystalline panels are darker in color, while polycrystalline panels have a traditional blue color.
While traditional monocrystalline panels still use black solar panels with white backsheets. Below you can see the difference. The image on the left shows a traditional monocrystalline silicon panel up close. The photo on the right shows the entire array panel with the black sheet, which is full black solar panel.
In terms of solar panel efficiency, the alignment of silicon crystals makes solar panels more efficient. When installing solar panels, less black solar panels are generally required than blue solar panels, and they will produce the same amount of solar energy, making black solar panels a more viable option for saving space.
In addition to solar panels being more efficient, black solar panels absorb more sunlight than other types of solar panels. This means that black solar panels are more capable of absorbing more sunlight, which means they will generate more solar energy.
Monocrystalline solar panels perform better at high temperatures. In the case of solar cells, the amount of solar power produced decreases as the temperature rises. However, a black solar panel will experience less attenuation of solar output than other types of solar panels.
For some architectural projects or design styles, black solar panels can provide higher aesthetic requirements. For architects and homeowners who care about appearance and design, black solar panels are a better choice because they are more in harmony with the overall appearance of the building.
black panels can be used as a part of the building exterior wall to add a unique visual effect to the building. This application method not only realizes the utilization of energy, but also endows buildings with more functions and aesthetic feeling.

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.
The vast majority of modern solar photovoltaic panels are made using silicon, a non-metallic element that is used in most modern electronics. Silicon is used in solar panels partly due to its ability to absorb most wavelengths of light and produce an electric charge. We can also manufacture near-perfect crystals at a relatively low cost. Differences in solar panels come from many sources, mainly the purity of the silicon used in the module. Most solar panels have a blue hue and are made with polycrystalline silicon, while the smaller percentage that appears black is made with monocrystalline silicon.
The silicon used in polycrystalline solar cells is made from raw silicon that has been melted and poured into a square mold. This process doesn't align the silicon perfectly, which results in the formation of many individual silicon crystals within the mold. The nature of the respective silicon crystals also produces the speckled, glimmering look and blue color characteristic of polycrystalline panels.
The polycrystalline cell manufacturing process leads to less waste and energy use than that needed to produce monocrystalline cells. As a result, polycrystalline solar panels are less expensive and much more widely used. Due to the lower cost of polycrystalline solar panel production, about 90 percent of the solar panels on the market today are polycrystalline; consequently, most solar panels have a blue hue.
The silicon used to make monocrystalline solar cells has a high level of purity. The silicon is all oriented the same way in a monocrystalline solar cell, creating one large silicon crystal. Because of how light interacts with a monocrystalline silicon layer, monocrystalline solar panels appear black. Aligning the silicon into one crystal, known as the Czochralski process, is energy-intensive and results in some wasted silicon. As a result, monocrystalline panels cost more than polycrystalline solar panels.
Black monocrystalline and blue polycrystalline solar panels both offer unique benefits and drawbacks. Due to their uniformity and the alignment of silicon in monocrystalline solar cells, monocrystalline panels tend to have a higher efficiency than polycrystalline panels. However, this higher efficiency comes with a higher price tag, as monocrystalline solar panels are generally more expensive to produce and buy. Polycrystalline solar panels have a less intensive production process (the silicon is less pure and doesn't need to be aligned), leading to lower prices for consumers and installers.
If efficiency is your main concern, a monocrystalline solar setup may be your best option. Likewise, if you want the lowest price for your solar project, polycrystalline panels could work best.
