Sun Position Results
This tool is widely used in fields such as solar energy planning, agriculture, architecture, photography, navigation, and environmental studies. By inputting simple location and time details, users can instantly get accurate solar position data without needing complex astronomical formulas or manual calculations.
Whether you’re planning solar panel installation, capturing perfect lighting for photography, or studying seasonal sunlight patterns, this calculator offers quick and reliable insights.
What Is a Sun Position Calculator?
A Sun Position Calculator is a digital tool that computes the sun’s position in the sky based on:
- Geographic coordinates (latitude and longitude)
- Date
- Time of day
It then calculates:
- Solar Elevation Angle – How high the sun is above the horizon
- Solar Azimuth Angle – The compass direction of the sun
- Day of Year – The numerical day within the year
These values help users understand sunlight direction, intensity, and availability at any moment.
How to Use the Sun Position Calculator
Using the tool is simple and requires no technical knowledge.
Step 1: Enter Latitude
Provide the latitude of your location.
- Example: 31.5204 (Lahore region)
Latitude determines how the sun’s angle changes based on your position on Earth.
Step 2: Enter Longitude
Enter the longitude of your location.
- Example: 74.3587
Longitude helps adjust solar time based on your exact location.
Step 3: Select Date
Choose the date you want to analyze.
This is important because the sun’s position changes throughout the year due to Earth’s tilt and orbit.
Step 4: Select Time (24-hour format)
Enter the exact time of the day.
For example:
- 06:00 → Sunrise period
- 12:00 → Midday
- 18:00 → Evening
Step 5: Click Calculate
The tool processes all inputs and instantly generates results.
Step 6: View Results
You will see:
- Solar Elevation (°)
- Solar Azimuth (°)
- Day of Year
- A short summary of sun position
Step 7: Copy or Share Results
You can:
- Copy results for reports or analysis
- Share results with others instantly
Understanding the Output Values
1. Solar Elevation
This represents how high the sun is in the sky.
- 0° = Horizon (sunrise or sunset)
- 90° = Directly overhead
Higher elevation means stronger sunlight intensity.
2. Solar Azimuth
This shows the direction of the sun on a compass:
- 0° = North
- 90° = East
- 180° = South
- 270° = West
It helps determine where sunlight is coming from.
3. Day of Year
This number represents the day in the calendar year:
- January 1 = Day 1
- December 31 = Day 365 (or 366 in leap years)
It helps calculate seasonal sun variations.
Practical Example 1: Solar Panel Installation
A homeowner in Punjab wants to install solar panels and needs to know the best direction and tilt.
Inputs:
- Latitude: 31.5
- Longitude: 74.3
- Date: June 1
- Time: 12:00
Results:
- High solar elevation
- South-facing azimuth direction
Use Case:
This helps determine the optimal angle for solar panels, maximizing energy production throughout the day.
Practical Example 2: Photography Lighting
A photographer wants natural lighting for an outdoor shoot.
Inputs:
- Location coordinates
- Date: October 15
- Time: 17:00
Results:
- Low sun elevation
- Warm directional sunlight
Use Case:
This allows photographers to plan shoots during golden hour, ensuring perfect lighting conditions.
