You’ll discover a few new terms and technologies as you research your solar energy options. One of the most common is choosing between roof or ground mounted solar panels.
You might have even been given this choice when looking at your home’s solar power. But there’s a difference, and knowing it can help you make a more intelligent decision.
So what are the differences between roof vs. ground mount solar panels, and which is best for you? We’re here to help. Keep reading for everything you need to know.
Rooftop vs. Ground-Based Panels
You can see the difference between roof-mounted and ground-mounted solar panels. Roof-mounted solar panels mount flush to the roof. They are also securely held with a metal frame and mounting hardware.
In comparison, ground-mounted solar panels are kept off the ground. And usually mounted at an angle to elevate their visibility and most excellent efficiency. Ground-mounted solar panels are easier to access for routine maintenance.
And you can repair them by reaching for a short ladder instead of being on the roof. Additionally, some people prefer the aesthetics of ground-mounted solar panels. It is because they blend into the landscape more than roof-mounted panels.
But, despite their somewhat lower efficiency, roof-mounted panels can offer more protection against strong winds. You can also mount it in more optimal locations for direct sunlight exposure. The potential of solar energy, whether roof or ground mounted, is incredible, and it has a high potential to generate clean, environmentally friendly energy in the long run.
Consequently, solar installers can be a great help in reducing emissions of harmful greenhouse gases to a large extent.

Whether you install your solar panels on the roof or the ground depends on your preferences and needs.
Pros And Cons Of Ground And Roof-Mounted
Ground and roof-mounted solar panels offer significant advantages and disadvantages for potential owners, so it is essential to consider these factors when deciding. The benefits and drawbacks of each are listed briefly below:
Ground Mount Advantages
- Easier Installation
Ground-mounted panels are easier to install than roof-mounted panels. They are self-contained and can be put in place more freely without worrying about roof strength or other environmental conditions.
- Increased Energy Generation
Ground-mounted solar panels are open. The solar panels get the most sun exposure possible, enabling you to produce more electricity.
- Flexibility
You can position solar panels on your property in any direction or at any number of places. It will allow you to arrange your array however you see fit and increases your ability to produce more solar energy. It is because the installation team may position the panels at various heights and angles for the best sun exposure.
- Improved Access
Solar panels on the roof are far less accessible than ground panels. Because of this improved access, they are simpler to care for, clean, and repair.
- Occupies Valuable Real Estate
To build ground-mounted solar panels, you need a secure foundation. So, ground mounted solar installations are often more suitable for large-scale commercial applications. It is where real estate is abundant, and acquiring land rights for an installation is necessary.
Ground Mount Disadvantages
- More Expensive
Solar installations using ground mounts are more expensive than those on rooftops. It is more costly due to the extra effort required in the installation process. Labor expenses are also higher.
It is because the installation on the ground typically requires more work and can be more time-consuming. Furthermore, land availability is also a factor in deciding between ground or rooftop mounting.
- Occupies Space on Your Property
Ground mount solar panels need more space since they must be located away from the home to get the necessary sunlight. It can be a significant issue if the homeowner has limited space outside their home to accommodate more installations.
- Prone To Damage
Ground mount solar panels are more susceptible to damage due to their exposure to the elements. And because they are on the floor, they are more vulnerable to vandalism, animal damage, and adverse weather conditions. And their mounting systems are also more prone to damage due to unforeseen events such as trees falling.
Additionally, dirt and debris can accumulate on the panel or its mounting system, potentially blocking sunlight. Similarly, theft is another issue that is more likely with ground mount systems, as the panels are more accessible to thieves.
- More Difficult Permitting Process
In some jurisdictions, you must keep the system far from the property line. Additionally, some utility companies need more permits due to their increased size.
Roof Mount Advantages
- Generally Less Expensive
Roof mounted systems are less expensive than ground installations as they don’t need to start from scratch. Your roof will already be strong enough to support the solar panels, so you won’t have to pay for additional materials. They typically have higher efficiency rates and rely less on installation and operational costs than ground-mounted systems.
Overall, roof-mounted solar panels are an excellent option for budget-conscious homeowners who want to use renewable energy sources.
- Space Efficiency
In the case of space-limited areas, rooftop solar panels are the perfect solution, as they can provide optimal output. Moreover, this takes up no extra space and provides an efficient and neat installation. Ultimately, the advantage of rooftop solar panels lies in their space efficiency, making them the perfect option for people looking to find a way to get full performance without using extra floor space and roof space.
- Avoids Shading
Roof mount solar panels offer the great advantage of avoiding shading. It is because they can be positioned almost anywhere along the top and can be angled to maximize direct sunlight exposure so that they will generate the most energy possible. Also, the panels can be positioned to minimize any shadows and reflections caused by nearby trees, buildings, and other obstacles.
Roof Mount Disadvantages
- Difficult to Access for panel maintenance
Roof mount solar panels can be located in hard-to-reach places and, as such, can be challenging to access for maintenance. Often, to carry out repairs or maintenance, technicians must climb onto a roof, potentially putting themselves and the panels at risk. Furthermore, the size of the panels may create additional access problems, particularly if the roof or nearby structures have limited room for working.
When an issue arises, attending to maintenance in a timely and safe manner can be a challenge.
- Limited Roof Space
The amount of space available on a roof may need to be increased to accommodate the size of the solar array. Secondly, solar panels mounted on roofs may need space out over many roofs, taking up further valuable roof space. It’s also possible that some roofs may need more space available for mounting the solar panels, limiting potential solar generation.
It’s also important to note that roof mounted solar panels may be less efficient than ground mounted as the space may be restricted.
- Can Affect the Optimal Setup
The roof pitch angle and shape interfere with the most excellent setup. In most cases, installing solar panels should face south at an angle of 30 to 45 degrees. When the roof is too steep or flat, it can impede the sunlight and energy output of the solar panels.
Additionally, in steeply pitched roofs, the roof’s structural integrity may be compromised, damaging in strong winds and extreme weather conditions. Furthermore, the shape and pitch of the roof can limit the angles available for panel placement, resulting in an inefficient design.
- Possibility of Roof Leaks
Solar panels mounted on the roof can increase the possibility of roof leaks. The roof connects the roof and the solar panel, creating a weak point. A leak may occur due to the solar panel system, and a roof can be compromised from its design.
When intense heat is applied to a poorly designed roof-mounted solar system, its structure can weaken due to uneven weight distribution. It can cause the roof to warp and create soft spots and existing cracks to expand, leading to roof leaks.
- Roof Repairs More Challenging
Roof mount solar panels are a great way to source green energy. However, they present unique challenges when it comes to roof repairs. When solar panels are mounted to the roof, it can become more difficult to access the roof, making roof repairs more challenging.
Repairs can be complicated if the roof has multiple panels that need to be removed to gain access to the top covering. Plus, solar panels can add weight to the total surface, leading to structural issues if the roof is not supported correctly.
- Heightened Risk Installation
When mounting solar panels, the installation team has a heightened risk due to unsafe conditions such as potential falls from heights or coming into contact with electric current. The rooftop must also be structurally sound to prevent any damage caused by the weight of the solar panels.
Roof Vs. Ground Mount Solar Panels
Ground mount solar panels benefit areas that need higher technology and more energy efficiency. In contrast, roof mounted panels are more suitable for residential use and have a lower installation cost. Regardless, ground and roof mounted panels are great options for those looking to switch to renewable energy sources.
