Introduction 

Solar energy collectors are crucial for converting solar radiation into usable forms like heat or electricity.

Types of Solar Collector

There are mainly two types of collectors: 1. Non Concentrating Collectors 2. Concentrating Collectors.

1. Non Concentrating Collectors

1. Flat Plate Collectors. 2. Liquid Collector. 3. Typical Air collectors or Solar Air Heater

2. Concentrating Collectors

A focusing collector is designed to capture solar energy with high intensity by using optical systems like reflectors or refractors.

Types of Concentrating Collectors

Two general categories of concentrating collectors are: (A) Line-focusing types (B) Point focusing types

Line-focusing collectors:

Parabolic Trough Reflector: In concentration, collectors like the parabolic trough collector, solar radiation is collected

2. Mirror Strip Reflector

A solar trough concentrator consists of a plane or slightly curved mirrors mounted on a flat base

Advantages of Concentrating Collectors

1. Reduced Material Usage. 2. Versatility. 3. Compact Design 4. Improved Efficiency

Disadvantages of Concentrating Collectors

1. Potential for Glare. 2. Higher Maintenance. 3. Limited Acceptance of Diffuse Radiation. 4. Tracking Requirements
