While capturing solar energy for commercial purposes we use

Options

A. Parabolic mirrors
B. Plane mirrors
C. Convex mirrors
D. Concave mirrors

Answer

To solve the question about what is used for capturing solar energy for commercial purposes, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Solar Energy Capture**:
- Solar energy can be captured using various technologies, but for commercial purposes, specific methods are more efficient.

2. **Identifying the Technology**:
- The technology commonly used for capturing solar energy on a larger scale is known as Concentrating Solar Power Technology (CSPT).

3. **Understanding CSPT**:
- CSPT utilizes mirrors or lenses to concentrate sunlight onto a small area, which can then be used to generate heat or electricity.

4. **Types of Mirrors Used**:
- The primary type of mirror used in CSPT is the parabolic mirror. These mirrors are shaped like a parabola and are designed to focus incoming parallel rays of sunlight onto a single point or a line.

5. **Function of Parabolic Mirrors**:
- When sunlight hits the parabolic mirror, it reflects and converges at a focal point where a receiver is placed. This receiver absorbs the concentrated solar energy, which can then be converted into thermal energy or electricity.

6. **Conclusion**:
- Therefore, the correct answer to the question is that for capturing solar energy for commercial purposes, we use Concentrating Solar Power Technology (CSPT) with parabolic mirrors.

### Final Answer:
While capturing solar energy for commercial purposes, we use Concentrating Solar Power Technology (CSPT) which employs parabolic mirrors.
