What are the advantages of double glass solar panels?

Solar panels play a major role in the performance and output of solar power generation systems. In a solar panel, solar glass is a component that decides the efficiency. Solar glass serves as a barrier that shields solar panels from external elements when sunlight passes through the panels and solar energy is converted into electricity.

There are two types of solar glasses. They are single-glass solar panels and double-glass solar panels.

Both types of glasses have their own positive and negative points in a Solar Power System in Brisbane.

Which one would you prefer? Well, the choice will decide how well and how long the solar power generation system will perform.

However, before you make the choice, it is essential to know their differences.

What is a Single Glass Solar Panel?

Single glass panels are also referred to as monoracial solar panels. In this panel, one sheet of glass covers the solar cells and shields them from external conditions.

The fundamental construction of a single glass solar panel is its front cover made of tempered glass, encapsulant material, solar cells, and a polymer or rear sheet material.

There is only one sheet of tempered glass over the solar cells in single glass panels. The construction of this panel is simple, you need just a single piece of glass to encase the cells.

Single Solar Panels in Brisbane have been in use for quite a long time.

What is a Double Glass Solar Panel?

On the contrary, a double glass solar panel, which is called a bifacial solar panel has a different design.

In this glass there are two transparent layers on the front and back.

The layers are filled with a transparent encapsulant. It increases the lifetime and durability of solar panels.

The double glass panels are different. In this, solar cells are put between two pieces of glass. Therefore, both the front and the back of the solar cells are protected from the weather.

Since there are two pieces of glass, the double glass panel is stronger and safer. These panels are more advanced than single glass panels because they have an extra layer of glass on top of them.

When you call a Solar Panel Installer, he will analyze and decide on which type of glass panel is right for you.

Durability

As far as durability is concerned, double glass panels take the lead. It is because they offer protection against environmental wear and tear, or fluctuation in temperatures. They can also resist hailstorms, intense rain, or strong winds.

Transmission of light

Double-glass panels often let more light through as compared to single-glass panels. They allow more light into the screen, which can improve its efficiency. Therefore, when you want to get more energy production out of your panels, double-glass panels might be better.

Thermal Stability

The thermal stability of double glass panels is better because there are two layers of glass. The two glass layers shield the solar cells from extreme temperatures.

Cost

Single glass panels are typically less expensive than double glass panels. Single glass panels are an affordable choice because they needless material for construction.

Advantages of N-type Solar Panels

Tempered glass, as the first layer material in the structure of solar panel modules, can effectively protect the solar cells and solar panels from physical stress, snow, wind, dust, and moisture, while allowing sunlight to pass through.

A double-glass photovoltaic module refers to a composite layer composed of two glass panels and solar cells. The solar cells are interconnected through wires to form a solar panel. The structure is fixed by an aluminum frame, providing strength during installation and preventing accidents and mishandling. In other words, from an appearance perspective, the back material of the traditional glass solar panel is replaced with glass in the case of a double-glass configuration.

Here is a comparison of the advantages and disadvantages between double-glass photovoltaic modules and traditional glass solar panels:

Compared to traditional solar panels, when the snow becomes thick or people step on them (during installation), solar panels tend to bend, leading to micro-cracks on the cells. The increased strength provided by the two layers of glass in double-glass photovoltaic modules greatly reduces the deformation of solar panels, thereby significantly reducing the possibility of micro-cracks. Glass, as the back material in double-glass modules (compared to plastic backsheet in traditional glass solar panels), is chemically inert. This means that the overall structure of double-glass photovoltaic modules (two layers of glass with solar cells in between) has strong resistance to chemical reactions, such as corrosion.

However, the cost of double-glass photovoltaic modules is higher compared to traditional solar panels, not only in terms of price but also in terms of the cost of failure rates. Double-glass photovoltaic modules are particularly prone to bubbles during lamination. Since both sides are made of glass, it is challenging to secure them, and when the solid adhesive turns into a liquid state during the high-temperature lamination process, it can easily slide or shift. Additionally, double-glass photovoltaic modules are heavier than single-glass modules, which can be a disadvantage for applications with weight restrictions.

Advantages of double-glass solar panels:

Enhanced structural strength: 

Double-glass solar panels enhance the structural strength of the solar cells, reducing the risk of deformation and micro-cracks.

Better protection: They provide better protection against physical stress, snow, wind, dust, and moisture, preserving the integrity of the solar cells.

Higher chemical resistance: Double-glass panels exhibit higher resistance to chemical reactions, making them more resilient against corrosion and damage.

Disadvantages of double-glass solar panels:

Higher cost: Double-glass panels tend to have higher costs, including both the purchase price and potential costs associated with higher defect rates.

Bubble formation during lamination: They are more prone to bubble formation during the lamination process, requiring stricter manufacturing processes.

Heavier weight: Double-glass panels have a relatively heavier weight, which may limit their suitability for applications with weight restrictions.

In summary, the advantages of double-glass solar panels include increased structural strength, better protection against various environmental factors, and resistance to chemical reactions. However, they come at a higher cost and may have challenges in terms of lamination quality control and weight compared to traditional glass solar panels.
