How Do You Place Solar Panels?

Placing solar panels effectively involves considering direction and angle for optimal sunlight capture.

Factors Affecting Solar Panel Placement

Several factors influence how you place solar panels, aiming to maximize energy production:

Direction:
- Northern Hemisphere: Solar panels should face due south.
- Southern Hemisphere: Solar panels should face due north.
- This ensures the panels receive the most direct sunlight throughout the day.
Angle/Tilt:
- The optimal tilt angle is generally close to your latitude. For example, if you're at 40 degrees latitude, a 40-degree tilt is a good starting point.
- Adjustments can be made based on seasonal variations. A steeper angle in winter can help capture more sunlight when the sun is lower in the sky, while a shallower angle in summer can be more effective when the sun is higher.
Shading:
- Avoid any obstructions that might cast shadows on the panels, such as trees, buildings, or other structures. Even partial shading can significantly reduce energy output.
Roof Orientation and Angle:
- Ideally, your roof will already be oriented towards the equator. If not, you may need to consider ground mounting or using specialized racking systems to achieve the correct direction and angle.
Panel Type:
- Some panel types are more sensitive to shading than others. Research and select panels that are appropriate for your specific site conditions.

Assess your location: Determine your latitude and identify potential shading issues.
Choose a suitable mounting location: Consider your roof's orientation and angle, or explore ground mounting options.
Select appropriate racking: Select a racking system that allows you to adjust the panels' direction and angle as needed.
Install the racking: Follow the manufacturer's instructions for proper installation.
Mount the solar panels: Securely attach the panels to the racking system.
Connect the wiring: Connect the panels to your electrical system according to local codes and regulations. This often requires a qualified electrician.
Optimize the angle: Adjust the tilt angle of the panels for optimal performance based on your latitude and seasonal variations.

Let's say you live in Denver, Colorado, which is at approximately 40 degrees north latitude.

Your solar panels should face due south.
A starting tilt angle of 40 degrees is recommended. You might increase this angle slightly during the winter months to maximize energy production.

Professional Installation: While DIY solar panel installation is possible, hiring a professional installer ensures safety, compliance with local regulations, and optimal system performance.
Local Regulations and Permits: Research local building codes and permit requirements before installing solar panels.
Net Metering: Check with your utility company about net metering programs, which allow you to receive credit for excess electricity generated by your solar panels.
