The PV photovoltaic systems ready to convert solar energy to electricity power are the results of the following manufacturing processes,
Their production requires complex, accurate manufacturing of machinery and equipment. The following post explains the most critical components of a PV production line related to PV modules, including the equipment used.
Basically, a PV module production machine is made of - a silicon Wafer, a Solar Cell, a Photovoltaic System, and a Solar Module.
Let’s understand the PV Module Production Equipment
Silicon Wafer:
Silicon wafers are one of those materials that can be seen in any kind of electronic equipment that helps humanity. Silicon is the second most available element in the universe, and it is used in the form of a semiconductor in the technological and electronic sectors.
- Silicon Wafers Applications: The ultra-pure silicon wafers provide a clean substrate on which to build the integrated circuitry at the heart of all electronics.
Solar cell:
A PV cell, or a solar cell for that matter, is a nonmechanical device that converts sunlight into electricity directly.
- Solar cell application:
Assemblages of solar cells are used to make solar modules that generate electrical power from sunlight, in contrast to a "solar thermal module" or "solar hot water panel". A PV Module generates solar power using solar energy.
Photovoltaic System
PV Module or PV technology is a devices that convert sunlight into electricity energy. Typically a single device produces 1 or 2 watts of power and it is known as a solar cell or Pv module production equipment. PV module production equipment is made of wafers or cells of semiconductor material that use the power of the sun's rays to generate direct current DC electricity.
Solar Module:
A group of connected solar cells represents a single photovoltaic Module/Panel, which will absorb sunlight as a source of energy to develop electricity. A group of PV modules (also known as PV panels) is wired into an extensive array called a solar panel to gain the required current and voltage.
Many people prefer Residential Solar Panel Installation in Delhi, which helps use solar energy effectively for the home power requirements.
When you decide to buy a solar power system, you will find three types, and being a layman, it is difficult to understand the difference between these technologies. So, let's have a look at these below:
- Types of Solar Module:
- Thin-film Solar Modules
- Polycrystalline Solar Modules
- Mono-crystalline Solar Modules
Tools used in PV Module Manufacturing Mchine
Cutting of Silicon Ingots
Purpose: To slice silicon ingots into very thin wafers that will serve as the raw material of the sun cell.
Tools: Multi-wire saw, Wire saw, or laser saw.
Importance: Cutting efficiency will determine the number of wafers that can be obtained and the cost of module production
Wafer Cleaning and Etching
Purpose: Removal of impurities from wafers and planarization to increase the output of the solar cell.
Apparatus: Chemical baths, ultrasonic cleaners, and plasma etching machines.
Importance: It is required to wash the wafers clean to ensure that the cell is deposited completely to ensure high cell efficiency and avoid the energy losses of a solar cell.
Cell Deposition:
It involves depositing layers of material on the surface of the wafer for the purpose of depositing the solar cell's active region.
Apparatus: CVD machines, sputtering systems, and screen printing machines.
Importance: The quality of the deposited layers determines cell efficiency in converting sunlight into electricity.
Cell Testing and Sorting:
Objective: To measure the performance of each cell and sort them according to the obtained efficiency.
Apparatus: Solar simulators, I-V testers, and sorting machines.
Importance: Precise measurement and sorting carried out through proper testing make sure only quality cells are put together in modules.
Cell Stringing:
Objective: To connect several individual cells in series to obtain a higher voltage.
Apparatus: Stringing machines with automated soldering or laser welding systems.
Importance: Good stringing avoids labor intensive and ensures that the electrical contacts are good.
Encapsulation:
Objective: To protect the cell strings from environmental influences and also give structural strength.
Equipment: Laminating machines, back sheet applicators, and edge sealant dispensers.
Importance: To ensure that PV modules have a longer life and also operate efficiently with high reliability, encapsulation is very important.
Module Testing:
Objective: To verify the module's electrical performance, mechanical strength, and conformity to industry standards.
Equipment: Solar simulators, I-V testers, thermal cycling chambers, and humidity chambers.
Importance: Proper testing ensures the quality and reliability of the final product.
Module Inspection and Packaging:
Objective: Identify defects or imperfections in modules and prepare for shipment.
Tools: Visual inspection systems, packaging machines, and labeling equipment.
Importance: The quality control measures ensure that the manufacturer's reputation is kept intact and not disappointed by customers.
Factors Impact on PV Module Manufacturing Efficiency
Several factors may affect the cost and efficiency with which a PV module will be produced:
Raw Material Costs: Silicon and other materials can easily affect the cost of production.
Equipment Costs: The initial investment in manufacturing equipment can be expensive.
Manufacturing Technology: The advancements in manufacturing technology might increase efficiency while lowering costs.
Energy Costs Production energy costs may have an impact on the overall cost.
Labor Cost: The cost of labor is yet another difference and will depend on the region and skill levels of the workers.
Manufacturing equipment for produced PV Module Production Equipment
Our PV module production equipment is the result of our research and experience. This means that the product is specifically made-to-measure to their requests and needs, assuring a very flexible operating method when defining the order and during the production process. A very efficient production of photovoltaic modules can be very rapidly installed.
