In recent years, the number of household solar panels has continued to increase, and more and more householders realize the convenience of solar energy system. At the same time, many home solar system owners have the same questions: which color of solar panels should I choose? Will different colors of solar panels produce different power generation efficiency? Does the color of solar panels need to match the roof?
If you know something about solar panels, you'll find that most solar panels are blue and black. The reason for the color difference is that these two types of solar panels interact differently with sunlight. Therefore, this article focuses on the design principles of these two different solar panel colors so that everyone can better understand their needs and clarify their choice direction.
The vast majority of modern solar photovoltaic panels are made of semiconductor materials, of which silicon is the most widely used. On the one hand, silicon can absorb most long wave light and generate electric charges. On the other hand, silicon, as an easily available material, enables solar manufacturers to produce nearly perfect crystalline at a relatively low price.
The most common blue solar panels are made of polysilicon. The main reason for the popularity of this panel is attributed to its anti-reflective coating, which helps to improve the absorption capacity and efficiency of the solar panel. The black solar panel, as a relatively new type, is made of monocrystalline silicon with higher efficiency because the black surface can absorb sunlight more naturally.
The silicon used in blue polycrystalline solar panels is made of raw silicon that has been melted and poured into a square mold. In the process of refining the original silicon, some materials cannot be perfectly aligned, which leads to the formation of many individual silicon crystalline in the mold. The nature of single silicon crystalline also produces the speckled, flickering appearance and blue characteristics of polysilicon panels.
Compared with the production of monocrystalline solar panels, the manufacturing of polycrystalline panels causes less material waste and energy consumption, so the price is cheaper and more in line with the budget of most householders.
The silicon in monocrystalline black solar panels has a very high purity. The silicon in this solar panel is obtained in the same way and eventually forms large silicon crystalline. The interaction between monocrystalline silicon and sunlight will make the solar panel appear black. The process of forming the large silicon crystalline wastes some materials, resulting in higher cost of monocrystalline solar panels.
3. How to Choose?
These two kinds of solar panels have unique advantages. Considering the uniformity of solar panels and the arrangement of the silicon, monocrystalline solar panels can often produce higher efficiency. However, such high-performance products are accompanied by higher price tags, so you need to consider whether your budget can afford it.
On the other hand, if you focus on aesthetics, the difference between a black monocrystalline panel and a blue polycrystalline panel may affect your solar purchase decision. Most of the current research shows that black solar panels can better match the color of the rooftop.
