Explore top 10 solar panel manufacturers in India, pioneering the green energy frontier.

How Solar Panels are Manufactured in India?

How is a solar panel made? What are the steps involved in the entire process? Dive in to take a detailed look:

Procuring Raw Material

The first step involves procuring raw materials like solar cells, encapsulants, tempered glass, frames, and junction boxes.  

Wafer Production

Many manufacturers produce wafers from crystalline silicon that come in various complementary shapes and sizes. 


Solar cells are a crucial part of the manufacturing process. A laser machine cuts the cells. The size of the cells depends on the wattage of the panels. Photovoltaic cell fabrication involves doping silicon wafers, applying the anti-reflective coatings, and passivating the cell surface. 

Solar Cell Assembly

Next, The cells are soldered and assembled together. It is an automatic process with minimal human intervention. All the cells are interconnected in a way to achieve the desired output and voltage. The blue or black hue is the negative part while the bottom white is the positive part.


The assembled cells are placed in a laminator and sealed with a back sheet and a tempered glass cover. Additionally, heat and pressure are applied to create a secure and durable bond between the components.


The laminated module is then framed using a steel or aluminium frame for structural support and protection.

Electrical Wiring

Next, all the electrical cables and junction boxes are attached to the back of the solar panels with interconnected diodes to achieve the desired electrical output.

Quality Control and Testing

The manufactured product goes through rigorous quality control checks to meet the specified standards for long-lasting performance and durability. The various tests include visual inspection, testing for hidden defects, and wiring checks.

To sum it up, the product is packed with instruction manuals and shipped to the final destination. There are numerous other processes involved and not all steps are needed always to manufacture a solar panel. It depends on the product type and the technology. Additionally, the degree of automation and quality control procedures vary among the top 10 solar panel manufacturers in India.

Now, that we have gone through the manufacturing process, let’s take a look at the top 10 solar panel manufacturers in India.
