What is Half-cut Cell Solar Module? Simple Guide
Many places have been installing Half-cut Cell Solar Module. But the lack of understanding about the system and panels is worth noting. Therefore, you need to learn about panels.
Let’s find out more details about solar panels with Anern marketing from concept, structure, what types of solar cells are available as well as the price!
I. What is a solar panel?
A solar cell or solar cell or photovoltaic cell (Solar panel) consists of many photovoltaic cells (solar cells) – a semiconductor element containing on the surface a large number of light sensors. Moreover, these are diodes optics. In addition, it converts light energy into electrical energy. The amperage, voltage, or resistance of solar cells varies depending on the amount of light shining on them.
Photovoltaic cells are assembled into blocks to become solar cells (typically 60 or 72 photovoltaic cells on a solar panel).
Half-cut Cell Solar Module is capable of operating under sunlight or artificial light. They can be used as light sensors (e.g. infrared sensors), electromagnetic emissions near the visible light threshold, or measure light intensity.
II. Construction of Half-cut Cell Solar Module
As mentioned above, photovoltaic cells are the main components and have the function of absorbing sunlight and converting it into electricity.
These crystalline silicon cells can be monocrystalline (called Mono batteries) or polycrystalline (called Poly batteries), depending on the manufacturing process of each solar cell manufacturer.
The main technical characteristics are size, color, and the number of cells – battery cells and most importantly, the conversion efficiency of solar cells.
Currently, the most common battery cells are Polycrystalline cells with a conversion efficiency of about 17.6%, making a 250W solar cell with 60 cells. Similarly, these cells link together by a thin copper wire coated with a tin alloy.
The front glass of a solar cell
The front glass of the 430W half solar panel is the heaviest part. Moreover, it has the function of protecting and ensuring the durability of the entire solar panel, maintaining high transparency. The thickness of this layer is usually 3.3mm but it can range from 2mm to 4mm depending on the type of glass that the battery manufacturer chooses.
Similarly, it is important to pay attention to factors such as hardness quality, spectral transmittance, and light transmission. The better the battery, the better this front glass absorbs the light that passes through, and the less light it reflects.
The back panel of the solar cell comes from a plastic material that electrically isolates, protects, and shields the PV cells from weather and moisture. In addition, this particular sheet is usually white and sold in rolls or sheets. Different brands of batteries may vary in thickness, color, and presence of specific materials for better shielding or for greater mechanical strength.
Finishing Packaging Materials Solar cells
One of the most important Half-cut Cell Solar Module materials is the packaging material. The adhesive between the different layers of the solar cell is important. Moreover, the most common material used as a packaging agent is EVA – Ethylene-vinyl acetate. It is an opaque polymer packed in rolls. Similarly, it must be cut into sheets and located before and after the photocells.
When subjected to a heat process of vacuum cooking, this special polymer becomes transparent glue and binds the photovoltaic cells. The quality of this process, known as lamination, ensures a long life for the panel itself and has an effect on light transmission, processing speed, and resistance to yellowing caused by UV rays.
Why should you use Half-cut Cell Solar Module?
- Create a green energy source
Sunlight is a natural source of energy familiar to everyone. Thanks to solar panels, that natural energy source is converted into electricity to serve human life.
- Environmentally friendly
A plus point for solar panels is to create a clean, environmentally friendly energy source
Half-cut Cell Solar Module – Solar Panel Frame
One of the final parts to assemble a solar panel is the frame. Generally, it is usually made of aluminum and has the function of ensuring the durability of the Half-cut Cell Solar Module.
For special use cases, frameless panels or special plastic solutions are also available. These solutions often involve the use of adhesive backing solutions with glazed glass technology.
The junction box has the function of bringing the electrical connections of the solar cell module to the outside.
It contains the cables to connect the panels in the system. When choosing the Junction box, we should pay attention to the quality of the plastic and the goodness of the coupling.
III. Types of solar panels available today
Types of solar batteries
Today, the main material for making solar cells (and for semiconductor devices) is crystalline silicon. Solar cells made from silicon crystals come into three types:
Half-cut Cell Solar Module comes into the process. Single crystals of this type are up to 16% efficient. They are often very expensive because they are cut from tubular silicon ingots. Moreover, these monoliths have blank faces at the corners connecting the modules. Similarly, they are also common as Mono solar batteries.
Polycrystals are made of ingots – cast from carefully cooled and solidified silicon molten. These batteries are usually cheaper than monocrystalline ones, but less efficient. However, they can form square sheets that cover more surface than monocrystalline compensating for its low efficiency.
The silicon band comes up of thin films of molten silicon and has a polycrystalline structure. This type is usually the least efficient. However, it is the cheapest of the bunch because it doesn’t need to be cut from a silicon ingot!
Solar panel efficiency
Efficiency is the ratio between electromagnetic energy and sunlight energy. At noon on a clear day, the sun radiates the heat of about 1000 W/m². where 10% efficiency of a 1 m² module provides about 100 W. Solar cell efficiency varies from 6% from amorphous silicon solar cells, and can be up to 30% or higher.
V. Latest price of solar panels
The Half-cut Cell Solar Module price will depend on a number of factors:
- The solar battery of Mono or Poly series?
- Moreover, the source of sale from Solar panel manufacturers
- How much or how little is the next battery?
