Aluminum Solar Panel Frame: The Ultimate FAQ Guide

What is Aluminum Solar Panel Frame?

Aluminum solar panel frame is a type of aluminum extrusion frame which you can use to fix and seal solar components.

Most of the solar panels have solar panel frames which hug the solar back sheets and glass covering at the top.

Why is Aluminum Solar Panel Frame Important?

Solar panel frames are important because of the following reasons:

• Solar panel frames fix and seal the solar modular components in one position for easier movement and installation.
• It protects the battery of the solar from falling out of place thus extending the service life of the solar panels.
• It protects the internal solar components from mechanical and thermal tension and subsequent damages.
• Solar panel frames also provide mounting brackets that you can use attachment points on to the roof of the building.
• Solar panel frames also assist in keeping other environmental factors such as water and dust from entering the solar panel.
• Aluminum has good conductive properties which can act as lightning protectors during thunderstorms.
• Aluminum solar panel frames are also strong enough, corrosion resistant, reliable and stable.

How many Aluminum Solar Panel Types are there?

There are three main types of solar panels which include:

• Monocrystalline solar panels
• Polycrystalline solar panels
• Thin-film solar panels

 Is there Recommended Aluminum Solar Panel Frame Thickness?

No, there is no recommended aluminum solar panel frame thickness.

However, you have to ensure that the solar panel frame is not too thin and weak.

It should not be too thick thus increasing the weight of the solar panel frame.

Does Wellste provide Custom Aluminum Solar Panel Frame Design?

Yes, Wellste provides custom aluminum solar panel frame designs.

Wellste has a team of engineers with enough experience to assist you with the custom solar panel design.

How Does Wellste Control Quality of Aluminum Solar Panel Frames?

Wellste controls the quality of aluminum solar panel frames by taking keen interest on the following features:

• Raw material

The main raw material that Wellste uses to manufacture aluminum solar panels is aluminum.

To ensure high quality, Wellste uses T5 aluminum alloy which has a higher tensile strength and offers resistance to corrosion.

• Surface

Wellste offers the best surface finishes for your aluminum solar panel frame.

To ensure quality, Wellste uses the anodized surface finish as it increases corrosion resistance in outdoor environments.

• Machining quality control

Wellste also ensures that the machining process is of very high quality.

It uses precise cutting machine that has a precision cutting tolerance to +/-0.1mm.

• QC inspector

Wellste has full time quality control inspectors who ensure that the aluminum solar panel frames are of high quality.

The inspectors refer to various quality standards in determining the quality of the aluminum solar panel frames.

• Packing

The packing process of the aluminum solar panel frame protects the solar panels from any damage during transportation.

It consists of different layers that keeps the solar frame intact thus protecting it from mechanical damages.

Which Aluminum Alloys is Suitable for Solar Panel Frames?

Aluminum solar panel frame components

The most common aluminum alloy that many manufacturers use is the T5.

T5 is the best choice because it has high tensile strength and is resistant to corrosion.

Apart from that T5 is light in weight, easy to machine, and saves you a lot on the extrusion process.

Which Surface Finishes can be applied on Aluminum Solar Panel Frame?

The surface finishes which you can apply on aluminum solar panel frames include:

• Sand blasting surface finishes
• Silver anodizing surface finishes
• Black anodizing surface finishes

The surface finishes assist in keeping the aluminum solar panel frame from mechanical damages such as scratches and corrosion.

Does Wellste offer Aluminum Solar Panel Mounting Frame Kits?

Yes, we can support your business with our aluminum solar mounting frames kits (solar panel mounting brackets).

Does Wellste have Standard Solar Frame Catalog to Save on Framing Tooling?

Yes, Wellste has a standard solar frame catalog that they can refer to thus saving on framing tooling.

The Wellste catalogue includes the following sizes:

• 25 mm by 25 mm
• 25 mm by 30 mm
• 30 mm by 35 mm
• 35 mm by 35 mm
• 35 mm by 40 mm
• 35 mm by 50 mm among other standard solar panel frame sizes.

Wellste also allows you to come up with a custom frame idea which they can assist to make a reality.

What Quantity of Aluminum Solar Frames can Wellste Produce per Day?

Wellste has the capability of meeting your production demands within a short period.

At Wellste we have 2 sets of machining line for solar panel frame production. We can produce sets per day.

Custom designs may take longer but as soon as the concept is in, the production is in a matter of minutes.

Why is aluminum frame of solar modules only black and silver

Why is aluminum frame of solar modules only black and silver

It is well known that aluminum frame is the core auxiliary material of solar modules.

In the context of the rapid growth of global photovoltaic installed capacity, some institutions estimate that the consumption of solar modules aluminum frame profiles will increase from about 1 million tons in to about 2.5 million tons in .

The new demand is showing rapid growth, but we have developed a strong interest in the appearance of aluminum frames, unlike the electrical frame and the electronic product frame, the solar aluminum frame can be made of various brilliant colors. It is only black and silver.

Why? Here is the detailed information:

1. Color difference

Solar panels have high requirements for color difference, and the color of the surface of the cells should be uniform, without a color difference.

Silver is the natural color of aluminum, and black is the stable color, which is not easy to have a color difference, so it is a better choice for aluminum frames as silver and black;

2. Color matching

The color of solar cells is generally dark, monocrystalline silicon cells are black, and polycrystalline silicon cells are dark blue.

The black frame is close to the color of the battery panel, and the color is more coordinated.

The silver frame forms a strong contrast with the battery plate, and it is also very beautiful and atmospheric, while the frame of other colors is not so atmospheric when installed on the black battery plate;

3. Cost

The cost of surface treatment is different, the solar frame has strong corrosion resistance, and the surface is anodized.

Natural color anodizing will save one coloring step, which can save costs, so the Matt silver solar aluminum frame is always the largest amount requirement in production, black anodizing cost will be higher than silver, but lower than other colors, so black solar  aluminum frame will be applied to solar modules in a small amount;

4. Application

Depending on the place of application, photovoltaic power plants are built in vast plains or hilly areas, and the requirements for aesthetics are not very high, but the requirements for corrosion resistance are relatively high

So anodized Matt silver and black can fully meet the color needs.

The electronic products are used indoors, have more contact with people, and their gorgeous appearance is more popular with customers, so the outer frame of electronic products has higher requirements on color.

The solar aluminum frame is an important auxiliary material with a high cost in Solar modules.

Aluminum profiles have the advantages of being lightweight, high strength, strong corrosion-resistance, easy cutting and recyclability, and are very suitable for bearing and fixing in solar modules.

According to the &#;China Photovoltaic Industry Development Roadmap&#; issued by the China Photovoltaic Industry Association, aluminum frame modules will account for 96% of the market in .

With the increase in module size and weight, the cover glass will be further thinned. Evolution, the role of the aluminum frame to strengthen the rigidity of components will be more important, and it is expected to remain dominant in the future.

According to the calculation of Huajing Industrial Research Institute, the aluminum frame accounts for about 9% of the component cost, which is one of the auxiliary materials with the highest cost proportion.

In , the global solar modules aluminum frame market size is expected to exceed 45 billion CNY and the industry has a broad space for development.

If it is assumed that aluminum prices remain stable, the market size of solar aluminum frames in is expected to exceed 45 billion CNY, corresponding to an average compound growth rate of nearly 20% from to , and the industry has a broad space for development.
