Solar Panel Position Calculator

Determine the optimal angle and orientation for your solar panels to maximize energy production. This calculator helps you find the best position based on your location and solar panel specifications.

How to Use This Calculator

To calculate the optimal solar panel position:

Enter your latitude and longitude coordinates
Select your solar panel type (fixed or tracking)
Enter the month you want to optimize for
Click "Calculate" to get your results

The calculator will provide the optimal tilt angle and azimuth (orientation) for maximum solar energy collection.

Formula Used

The optimal solar panel angle is calculated using the following formula:

Optimal Angle = Latitude - 15° (for fixed panels) Azimuth = 180° (south-facing)

For tracking panels, the azimuth follows the sun's path with a slight tilt adjustment.

Note: This is a simplified calculation. Actual optimal angles may vary based on local weather patterns and shading considerations.

Worked Example

Let's calculate the optimal position for a fixed solar panel in New York City (latitude 40.7128° N, longitude -74.0060° W):

Enter latitude: 40.7128
Enter longitude: -74.0060
Select panel type: Fixed
Select month: June
Click Calculate

The calculator will show:

Optimal tilt angle: 25.7128°
Optimal azimuth: 180° (south-facing)

This means your solar panels should be tilted 25.7128° and facing true south to maximize energy production in June.

Interpreting Results

The calculator provides two key pieces of information:

Optimal Tilt Angle: The angle your solar panels should be tilted from horizontal. For fixed panels, this is typically your latitude minus 15°.
Optimal Azimuth: The compass direction your panels should face. South-facing (180°) is generally optimal for most locations in the Northern Hemisphere.

For tracking panels, the azimuth will follow the sun's daily path, and the tilt angle will adjust throughout the year.

Frequently Asked Questions

Why is the optimal angle different for different months?: The sun's path changes throughout the year. In winter, the sun is lower in the sky, so panels need to be tilted more steeply to capture maximum sunlight.
Does this calculator account for shading from nearby objects?: No, this is a basic calculation. For accurate results, you should consider local shading when installing your solar panels.
What's the difference between fixed and tracking panels?: Fixed panels stay in one position year-round. Tracking panels follow the sun's movement throughout the day, generally producing more energy but at a higher cost.
Can I use this for solar thermal systems?: Yes, the same principles apply to solar thermal collectors, though some systems may have different optimal angles for maximum heat collection.
