Solar panels are becoming popular these days in the energy department. The use of solar panels is rising rapidly. But why is that?

Solar plants have the capacity to generate electricity for homes and businesses alike. Alternative energy sources have grabbed the consumers’ attention in the past few years. The industry is booming thanks to proactive policies and a rising shift towards renewable energy. 

Feeling uncertain about selecting the best solar panels in India from emerging brands? Let this guide provide the clarity you need – we’ve got your back. We have carefully curated a list of the top 10 solar panel manufacturers in India. Several domestic brands are changing India’s solar energy landscape with performance-focused solar products.

Let’s begin with understanding how solar panels are manufactured.

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. 

Fabrication

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.

Lamination

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.

Framing

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.
