explain the relations between the different kinds of angles involved in solar radiation analysis

Solar radiation analysis involves several types of angles that are crucial in understanding the solar energy potential at a specific location. Here are the main angles involved:

1. Solar declination angle (δ): This is the angle between the equator and the Sun's position in the sky, measured along the Earth's surface. It changes throughout the year due to the Earth's tilt and revolution around the Sun.

2. Solar altitude angle (α): This is the angle between the horizontal plane and the Sun's position in the sky, measured from the ground level. It varies throughout the day and is dependent on the time of the year.

3. Solar azimuth angle (az): This is the horizontal angle between the Sun's position and a reference direction, usually true north or magnetic north. It determines the direction from which the Sun is coming.

4. Latitude (φ): This is the angular distance of a point on the Earth's surface from the equator, measured north or south along the Earth's meridian. It plays a significant role in determining the Sun's position in the sky at a specific location.

5. Hour angle (H): This is the angle between the Sun's meridian (the imaginary line passing through the celestial poles and the Sun) and the observer's meridian. It helps in calculating the Sun's
 In solar radiation analysis, several types of angles are involved, and understanding the relationships between these angles is crucial for accurate calculations and modeling of solar radiation. Here are the main kinds of angles involved and their relationships:

1. Solar Zenith Angle (SZA): The angle between the direction of the sun and the vertical direction (zenith) at a given location. The SZA varies throughout the day and year, and it is an essential parameter in solar radiation calculations.
2. Solar Azimuth Angle (SAA): The angle between the projection of the sun's position onto the horizontal plane and a reference direction (usually true north). The SAA indicates the sun's horizontal direction and changes throughout the day as the sun moves across the sky.
3. Surface Slope Angle (SSA): The angle between the horizontal plane and a surface (such as a solar panel) that is intended to receive solar radiation. The SSA affects the amount of solar radiation that reaches the surface and is an essential parameter in solar energy system design.
4. Surface Azimuth Angle (SAzA): The angle between the projection of the surface normal onto the horizontal plane and a reference direction (usually true north). The SAzA indicates the surface's horizontal orientation and is also an essential parameter in solar energy system design.
5. Angle of Incidence (AOI): The angle between the direction
