What does a solar cell panel consist of?

1. Solar Cells

   The most crucial component, responsible for converting sunlight into electricity.Solar cells are typically made of silicon, which comes in two main types:

   - Monocrystalline Silicon: High efficiency and long lifespan.

   - Polycrystalline Silicon: Lower cost but slightly less efficient.

   
   

2. Front Glass

   - Protects solar cells from impact, dust, and water.

   - Made of tempered glass, which is durable and resistant to weather changes.

   
   

3. EVA Layer (Ethylene Vinyl Acetate)

   - A transparent layer that bonds solar cells to the front glass and backsheet.

   - Helps prevent moisture and extends the lifespan of the solar cells.

   
   

4. Backsheet

   - Protects the solar cells from damage caused by moisture and UV radiation.

   - Commonly made of durable materials like TPT or PVF.

   
   

5. Frame

   - Made of aluminum, corrosion-resistant.

   - Adds strength and stability to the panel.

   
   

6. Junction Box

   - The connection point for electrical wiring.

   - Contains bypass diodes to prevent reverse current.

   
   

7. Cables and Connectors

   - Used to connect the solar panel to the electrical system.

   - MC4 connectors are commonly used for secure and waterproof connections.

   
   

8. Anti-reflective Coating

   - A surface coating that reduces light reflection and increases light absorption.

   
   

These components work together to ensure the solar cell efficiently generates electricity, remains durable, and operates reliably over time.
