As the name suggests, all-black solar panels are solar panels that are designed to be black in color.

What is the difference between all-black solar panels and blue solar panels?

1. All-black solar panels have different types of silicon panels.

Traditional blue solar panels belong to polycrystalline silicon panels, made of polycrystalline silicon panels, polycrystalline silicon panels are made by melting silicon crystals, and then inverted molds to form rectangular silicon blocks used to make solar panels. And all-black solar panels is a monocrystalline silicon panels, monocrystalline silicon panels are made by melting silicon seed crystals, which will form a special ingot crystal structure, and then inverted molding of these molten silicon to form a single thin silicon plate, and finally made of monocrystalline silicon panels.

2. The power generation efficiency of all-black solar panels is different from that of blue color

Because all-black solar panels are more heat-absorbing compared to blue panels, all-black solar panels are equipped with black backsheets and black frames that lead to higher overall panel temperatures when running for power generation, resulting in it not being able to be like blue solar panels with white backsheets that provide gaps that can secondarily absorb the reflected sunlight when it finds the panels and the possibility of absorbing and capturing reflected sunlight is smaller, resulting in it not being able to absorb and capture the reflected sunlight. The possibility of absorbing and capturing the reflected light from the sun is smaller, resulting in a lower efficiency of its power generation.

What are the advantages and disadvantages of all-black solar panels?

Advantages of all-black solar panels

1. Longer life cycle of all-black solar panels

All-black solar panels are made of monocrystalline silicon panels, compared to polycrystalline silicon panels, monocrystalline silicon panels can reach a service life of more than 25 years, while polycrystalline silicon panels can only reach about 20 years.

2. All-black solar panels are more beautiful from a distance

Generally speaking, the installation of solar panels for home use will cover most of the area of the roof, so when choosing solar cells, aesthetics is one of the important references for users to buy. Compared with the traditional blue solar panels, homeowners generally choose all-black solar panels to get a smoother, more beautiful appearance.

3. All-black solar panels can reduce winter glare interference

Generally, traditional solar panels use aluminum silver bracket, although more beautiful, but the ability of aluminum reflection of sunlight is stronger, especially when used in residential areas, sunlight reflection of the formation of silver glare will not only interfere with the daily life of the neighbors, affecting the relationship between neighbors, and may even have the risk of blindness. The all-black solar panel can reduce these reflected glare, especially in areas with high building density and narrow spacing.

4. All-black solar panels have better snow melting ability in winter, which can reduce the number of manual snow removal.

The black bracket used for all-black solar panels can absorb more heat in winter, accelerate the melting of snow and ice in the snowy season, reduce the impact of winter icing and snow on the normal use of solar panels, and avoid frequent manual snow removal in winter. This makes all-black solar panels more suitable than blue panels for use in areas prone to snow and ice in winter.

Disadvantages of all-black solar panels

1. All-black solar panels have low power generation efficiency

Although the efficiency of monocrystalline silicon panels is usually higher than that of polycrystalline silicon panels, the color characteristics of all-black solar panels make it work at higher temperatures, and the possibility of secondary absorption and reflection of sunlight is lower, and the power generation efficiency is even lower.

2. Higher cost of purchasing all-black solar panels

First of all, all-black solar panels in the production process of the choice of materials to control the more stringent, in order to control the material of all-black, but also need to be configured in which the photovoltaic glass, battery cells and other important components, are to do a unified batch, the color of the same color without color difference. This is also the production of all-black solar panels need to face important issues. Controlling materials without color difference will increase the difficulty of manufacturing all-black solar panels. Secondly, the monocrystalline silicon panels used in all-black solar panels are also more expensive than polycrystalline silicon panels. This also contributes to the high price of all-black solar panels.

And in the long run, the time to purchase all-black solar panels to get the report is short, so the price difference between the two may be flat in recent years, so most people do not recognize the high price of all-black solar panels at this time.

Black materials used in all-black solar panels and the role they play

Black Backsheets and Frames

In order to reach the aesthetic needs of all-black solar power panels, generally supporting the use of all-black backsheets and frames. The black frame made of aluminium can meet the smooth and uniform all-black appearance while reducing the reflected glare. And the all-black backsheet is generally made of some special materials to help further reduce reflections.

Black Glass

First of all, we need to know that the front side of the solar panel is made of glass, and this glass needs to maintain a high light transmittance so that the sunlight passes through the glass and hits the cell directly underneath, thus absorbing more light energy. The double-glazed solar panels on the market have a glass backside that replaces the backplate for greater advantage. However, the back of traditional double-glazed solar panels is generally made of transparent glass, which means that the back of the sink bars and other components are visible, but if the double-glazed all-black solar panels add a black mesh structure to the glass on its back, it can protect these sink bars and other important components while ensuring that the back of the panel also presents a perfect all-black color.

Black encapsulation, black silicone and busbars and contacts

The choice of black color for these components reduces the visibility of cluttered components, achieves overall uniformity, and enhances the overall aesthetics of the all-black solar panel.

Different appearance types and characteristics of all-black solar panels

All-black with all key components in black color

Beautiful appearance, smooth and elegant high-level.

The type of black frame with white backsheet

Black frame can enhance the overall aesthetics, while matching with white backsheet can reflect and capture more sunlight, improving efficiency while realizing the aesthetics.

Silver Frame with Black Backsheet

From a distance, it can look almost like an all-black solar panel, but pairing it with an aluminum silver frame can help reduce the cost of the panel.
