When you look at a solar panel on a rooftop, it seems like a simple product—just a shiny rectangle soaking up the sun. But behind that sleek surface lies a world of intricate engineering, advanced machinery, and rigorous quality control. At Sova Solar, we pride ourselves on not just manufacturing solar panels, but crafting energy solutions that are built for performance, durability, and sustainability.
As a leading solar company in Kolkata and one of the most trusted solar panel manufacturers in Kolkata, we take you on a behind-the-scenes journey through the Sova Solar assembly line—where every solar panel is made with precision to deliver maximum output for years to come.

Why Precision Matters in Solar Panel Manufacturing

Solar panels are not just about capturing sunlight—they’re about doing it efficiently and consistently. One tiny defect in a cell or misalignment in the layers can result in lower energy production or a shorter lifespan. That’s why precision isn’t just a preference at Sova Solar—it’s a necessity.
Being a well-recognized solar company in Kolkata, our mission is to combine world-class technology with Indian climate readiness. Our panels are engineered to thrive in diverse conditions—be it the scorching heat of Rajasthan, the coastal humidity of Kerala, or the pollution of metro cities like Kolkata and Delhi.

The Sova Solar Assembly Line: Step-by-Step

Here’s how we manufacture each solar panel—from raw materials to a powerful energy-generating device.

1. Purifying Silicon and Creating Wafers

We begin by purifying silicon through a specialized chemical process that removes impurities. The result—solar-grade polysilicon—is melted into ingots and sliced into ultra-thin wafers using high-precision wire saws.

These wafers form the foundation of our solar cells. Any deviation in thickness or texture can compromise performance, so we rely on state-of-the-art machines to ensure consistency.

2. Solar Cell Fabrication
These wafers are then transformed into energy-producing solar cells via a meticulous process that includes:

• Surface texturing to reduce sunlight reflection
• Doping with boron and phosphorous to create positive and negative layers
• Printing silver contacts for current flow
• Adding an anti-reflective coating to maximize light absorption

Each cell undergoes electrical testing, and only the most efficient ones are moved forward.

3. Cell Interconnection (Stringing and Tabbing)
We connect individual cells using copper ribbons in a process known as tabbing and stringing. Multiple cells are joined to form a string, and these strings are then arranged in precise series-parallel combinations to match the desired panel output.

4. Layering and Lamination
Next, the cells are layered like a sandwich:

• Tempered glass on the front for protection
• EVA encapsulant sheets to cushion and hold components
• Backsheet to block moisture and UV radiation

These layers are sealed under heat and pressure in a laminator, resulting in a durable, weather-resistant panel.

5. Framing and Junction Box Installation
An aluminum frame adds structural support and simplifies mounting. Then, we attach a junction box to the back of each panel. This junction box:

• Connects the panel to other electrical systems
• Enables series or parallel configurations
• Protects connections from moisture and temperature changes

Each component is selected for its durability, ensuring the panel lasts over 25 years.

6. Quality Testing and Inspection
As one of the most quality-driven solar panel manufacturers in Kolkata, we leave nothing to chance. Every panel undergoes:

• Flash Testing to confirm power output
• Electroluminescence (EL) Testing to spot invisible defects
• Hi-Pot and Insulation Testing to prevent leakage
• Visual Inspections to catch any cosmetic imperfections

Panels that don’t meet our standards are reworked or recycled—not sold.

• 7. Packaging and Shipping
  After testing, panels are:
• Labeled with unique IDs
• Packed in shock-absorbing materials
• Registered in our system for warranty tracking

Whether it’s a rooftop in Kolkata or a solar farm in Gujarat, we ensure our panels arrive in perfect condition.
