### **What is a Solar Panel?**
- A solar panel is a device that converts sunlight into electrical energy.
- It is also called a **Photovoltaic (PV) Panel**.
- It is the primary source of converting solar energy into electricity.

### **Types of Solar Panels**
1. **Monocrystalline Solar Panels**
- High-efficiency panels.
- Made from single-crystal silicon.
- Expensive.
2. **Polycrystalline Solar Panels**
- Lower efficiency panels.
- Made from multiple silicon crystals.
- Cheaper.
3. **Thin-Film Solar Panels**
- Lightweight and flexible.
- Lower efficiency but easy to install.

### **Working Principle of Solar Panels**
, - Solar panels work on the **Photovoltaic Effect**.
- When sunlight falls on a solar cell, it energizes electrons, generating an
electric current.
- This process is facilitated by semiconductor materials (e.g., silicon).

### **Components of a Solar Panel**
1. **Solar Cells**
- The main part of the panel that converts light into electricity.
2. **Glass Cover**
- Protects the solar cells from external damage.
3. **Frame**
- Provides support and protection to the panel.
4. **Inverter**
- Converts the generated Direct Current (DC) into Alternating Current (AC).
