What are the Different Types of Solar Panel Mounts

Here at SolarFasten we know as the world continues to embrace renewable energy sources, solar power has emerged as a leading contender in the race to reduce carbon emissions. Solar panels, the heart of solar energy systems, are essential components that require effective mounting solutions.  When it comes to solar panel mounts, there isn’t a one-size-fits-all approach. The choice of mounting type depends on various factors such as location, space constraints, and design considerations. In this blog post, we’ll explore the different types of solar panel mounts, each with its unique advantages and disadvantages. 

Ground Mount

The ground mount is a popular choice for solar panel installations, especially in areas with ample space. This type of mounting structure allows multiple rows of dollar panels to be securely installed on the ground. Some key advantages and disadvantages of ground mounts include:

Advantages

• Cooler module temperature: Solar panels can generate a significant amount of heat during the day. Ground mounts allow for natural convection, helping to cool down the panels.
• Safe installation: No climbing is required, making installation and maintenance safer.
• Easy access for maintenance and troubleshooting.
• No roof penetration: Ground mounts eliminate the risk of roof damage or liability.
• Flexible positioning for maximum production: Ground mounts can be adjusted to optimise the tilt angle for increased energy production.

Disadvantages

• Vulnerable to theft, vandalism, or damage.
• Requires earth construction work, including concrete foundations and trenching.
• Space requirement: Ground mounts occupy significant space, which may not be suitable for all locations.
• Inter-row shading considerations: Shading between rows of panels can affect overall energy production.

Pole Mount

Pole mounts are commonly used in public areas or locations with space constraints. They involve mounting solar panels on a single pole. Here are some advantages and disadvantages of pole mounts.

Advantages

• Cooler module temperature.
• Easy access for maintenance and troubleshooting.
• No roof penetration, reducing the risk of damage. 
• Flexible positioning for maximum production.
• Easy tilt angle adjustment, potentially allowing for dual-axis tracking.
• Small footprint: Requires only one pole.

Disadvantages

• Vulnerable to theft, vandalism, or damage.
• Requires construction work, including the installation of concrete foundations and steel poles. 

Roof Mount (without roof penetration)

Roof mounts are an excellent choice for locations with limited ground space, especially when the roof is flat. Ballasted roof mounts, in particular, use the weight of concrete or sand to secure the system without penetrating the roof. Here are some advantages and disadvantages of roof penetration:

Advantages

• Lower material cost.
• Utilises otherwise unused roof space. 
• Provides secure access for authorities personnel. 
• Flexible positioning for optimal production.
• No roof penetration, eliminating roof leak liability.

Disadvantages

• May require structural engineering and/or roof reinforcement due to added weight.

Roof Mount (with roof penetration)

In some cases, roof mounts may require roof penetration, especially on pitched roofs. Here are some advantages and disadvantages:

Advantages

• Lower material cost.
• Utilises otherwise unused roof space.
• Provides secure access for authorised personnel.

Disadvantages

• Requires professional installers.
• Higher module temperature due to poor ventilation.
• Difficult conduit runs through the roof.
• Fixed tilt and orientation are determined by the roof’s pitch and orientation. 
• Pullout forces from wind can pose a challenge, requiring secure attachment mechanisms.

Considerations for all roof mounts

Roof age - Ensure the roof can support the added weight of solar panels. 

Snow and wind loading - Assess the roof’s capacity to withstand additional loads.

Fire issues - Collaborate with local fire departments to address fire hazards and accessibility in case of a fire.

 

 

Selecting the right solar panel mount is crucial to the efficiency and longevity of your photovoltaic system. Each type of mount has its own set of advantages and disadvantages, making it essential to consider your specific needs and constraints when making your choice. Whether it’s a ground mount, pole mount, or roof mount, understanding the pros and cons of each will help you make an informed decision for your solar panel installation. As solar technology continues to advance, it’s important to stay informed about the latest mounting solutions to maximise the benefits of solar energy.
