Solar energy has become increasingly popular in the past decade and the decision to install a system is beneficial for home and Business owners. Before you do so, it’s important to understand the different options available for mounting solar panels. Solar Ground Mount vs. Roof Mount Racking, both types of solar mounts – offer their own benefits and drawbacks. It’s up to you as a homeowner to decide which option is best for you and your living space.
Roof mounts are typically less expensive than ground mounts, due to the fact that they use your existing roof structure as a base. These mounts take up less room on your property, as they don’t require the additional space that ground mounts do. However, installation and repair can be more difficult as they must be accessed from a higher level.
Ground mounts, on the other hand, are easier to access for installation and repair. In addition, ground mounts are also more versatile, giving you greater control over your array’s specific orientation to maximize production. They also typically require a larger footprint on your property.
When it comes to selecting a solar system installation, ground-mount solar systems offer many distinct advantages. Finding the perfect alignment is one of the key benefits of investing in a ground mount.
First and foremost, ground-mounted systems can be perfectly aligned to face directly at the sun no matter where on the Earth the system is being installed. This level of customization allows you to maximize the efficiency of the system by ensuring that it receives a maximum amount of sunlight.
For example, if the system is being installed in Europe, it will be positioned to face south in order to capture the most sunlight. Similarly, if the system is being installed in South America, it would need to be aligned to face north due to the Earth’s orbit. Finding the perfect alignment is not an option for roof-mounted systems, as it’s unlikely that a roof naturally faces directly into the sun.
Therefore, ground-mounted systems can produce significantly better results than their roof-mounted counterparts. In addition, ground mounts mitigate many of the structural challenges and installation limitations associated with roof-mounted systems.
Having the perfect alignment for a solar array is essential to achieving maximum efficiency. No matter what type of solar system you have, it will benefit from getting as much direct sunlight as possible. In the United States and other parts of the Northern Hemisphere, the most efficient direction to face solar arrays is south. This is true as the Sun’s path leads southwards as it orbits the Earth.
However, for those who live in the Southern Hemisphere, such as South America, the more efficient direction for an array is true north. Aligning a rooftop system to the optimal direction of the sun can be difficult, as your roof may not face the exact spot needed.
Ground-mounted systems, on the other hand, can be adjusted in any direction to capture the most direct sunlight throughout the day. By aiming your solar panels in the right direction, you can the most out of your system, enabling maximum efficiency and power.
for consumers looking for the most efficient, cost-efficient, and aesthetically pleasing ways to integrate renewable energy into their homes, ground-mount arrays offer a clear set of advantages over grid-tied or off-grid systems.
Ground-mount arrays are a great way to increase energy production, as the solar array is not restricted by the intensity of the sun. The perfect angle isn’t the only thing that makes ground-mount arrays more efficient- they are also raised off the ground, which allows for better airflow and cooling, thereby increasing the efficiency of the panels.
Increased airflow and cooling allow the solar panels to operate in optimal conditions, greatly reducing the amount of lost energy. When it gets too hot out (e.g. hotter than 77° Fahrenheit), sunlight can heat up the solar panels, leading to a decrease in electricity production. Heat waves create resistance to the flow of electricity, much like squeezing a hose while water is flowing through it. Ground-mount arrays keep the panels cooler, allowing them to generate more energy.
Installing solar panels on your roof can be an effective way to generate solar energy from the sun’s rays, but the amount of usable space you have for the system is usually quite limited. This means that as your energy needs change in the future, adding additional panels to your existing system could become a challenge.
Ground-mount solar arrays, on the other hand, offer much more space flexibility and expandability. Provided you have the space available in your yard, ground-mount installations can be easily modified, extended, and expanded as needed, with new additions easily added with the right mounting systems.
This capability to increase the size and scale of your system provides many great potential benefits: As you add on to your property in the future and require additional wattage, you have the ability to add more panels to your solar installation; likewise, if the initial size of your system falls short of your needs, you can supplement your current energy production with additional panels.
Ground mounted solar systems have a major advantage when it comes to accessibility. With a rooftop system, technicians have to battle against their fear of heights every time they need to perform maintenance or adjustments. This means weather conditions, access corridors, etc. must all be taken into account when deciding where to place the panels. Ground mounted systems, on the other hand, provide a much more accessible platform for problem-solving and maintenance. This is especially advantageous if your installation includes components such as microinverters and optimizers, which can be difficult to replace on a rooftop setup.
In the event of a malfunction in your system such as a broken microinverter located between two solar panels, the situation can be addressed much more quickly and effectively with a ground-mounted panel, rather than having to have workers remove several panels to access the source of the problem.
The ability to stand directly under and beside a ground-mounted solar panel also provides homeowners and technicians with a safer environment for regularly scheduled maintenance and for cleaning off panels covered with snow. This added accessibility serves to provide homeowners with added peace of mind when it comes to their investments in solar energy.
Building a solar energy system for your home or business doesn’t come without drawbacks. One of the most important considerations you must make when installing a system is choosing between ground-mount and roof-mount racking systems. Ground-mount racking can be a great solution, as it can lead to more efficient energy production, but there are certain drawbacks that you need to consider before installation.
One of the primary drawbacks of a ground-mount racking system is that it is more labor-intensive and requires more cost upfront. Securing solar panels to a roof is generally easier than mounting them on the ground, and roof-mount racking systems can often be more cost-effective. Another issue to consider is the long permitting process for a ground-mount system. You’ll need to submit a design plan to the local authority, taking into account factors such as soil type and property line requirements, and there may be additional fees associated with the process. Finally, ground mounts take up a large amount of space on your property, which could be better used for other purposes.
The decision to go with a ground-mount or a roof-mount racking system is ultimately up to you, but you should consider all the pros and cons before making your final choice. It’s important to weigh up the potential costs and the amount of labor required before committing to a ground-mount system. If you’re looking for an efficient way to maximize your energy production, then a ground-mount system might be a good choice. With careful planning and research, you can ensure that you have the best system in place for your needs.
There are three main questions to ask yourself to make sure ground-mount will work for you.
The first thing you need to consider is how much are you looking to spend upfront. Installing a ground-mount racking system requires more labor and parts to install it. Therefore, you may need to partner with a contractor to get the job done, and the permitting process will also be lengthier and more expensive. If a large investment initially is an issue for you, then you may want to consider putting the panels on your roof instead.
The second important factor is what kind of soil you have. If your property is on bedrock, or if you know that the soil is going to be really difficult to dig into, you may want to opt for a roof-mount system. Hard soil can make installation costs for ground-mount systems skyrocket, so it’s not impossible, but you will definitely need to rent heavy-duty equipment to drill into the ground.
Finally, there are also a few workarounds with ground-mount options to keep the digging to a minimum. One of the solutions would be a ballasted system, where heavier items such as sandbags, concrete blocks, or steel plates are used instead to secure the panels to the ground. When you’re researching what option is the best for your property, you’ll need to make sure that the ballast is placed correctly for maximum efficiency.
The main benefit of a ground mount system is that you can add more solar panels as your energy needs change over time. You will also likely benefit from the built-in tilt of the ground mount system that is designed to get the optimal amount of sunlight at all times, which may not be possible on a rooftop.
It is important to consider the size of your energy system if you plan on living off-grid. Too small a system may mean that you are unable to meet all of your energy needs and will require you to source energy from elsewhere. Conversely, too large a system could lead to inefficient use of resources, which could lead to wasted energy and upcoming costs.
| Pros of Ground Mounts | Cons of Ground Mounts |
|---|---|
| Easy to access and troubleshoot | More labor-intensive and expensive installation process |
| Allows for stronger racking overall | More parts, pieces, and tools required |
| System dimensions are not limited by roof dimensions | Can be more expensive from a permitting standpoint |
| Can increase energy output with cooler panel temperatures | Can take up real estate |
| No need to remove panels when the roof is replaced | May not be aesthetically pleasing to all viewers |
A roof-mount solar racking system may be preferable for customers who seek a higher return on their investment, require an uncomplicated installation process, and do not have abundant space. Additionally, those looking to save money in the short term may opt for a roof-mount racking system. However, there is no one solution that is unequivocally better than the other. The most advantageous choice depends on the individual’s budget, energy needs, and lifestyle.
A roof-mount racking system is a perfect solution for many homeowners. Roof mounts require fewer materials and labor upfront and can save thousands of dollars that would otherwise go toward the ground-mounted system.
When you go with a roof-mount racking system, you won’t have to worry about having your soil surveyed, digging holes, and purchasing expensive materials, like poles and concrete. This makes it ideal for grid-tie customers who are looking to make a smart and cost-effective investment.
Besides the monetary benefit, a roof mount takes advantage of unused space. This is especially beneficial for people who are living in condos or tightly-packed suburbs and lack extra land for a ground-mounted system. This way, you can still take advantage of the benefits of solar while still preserving precious land for other activities.
When considering solar, one unexpected benefit is the protection it can offer to your roof. By installing solar panels on top of your roof, you’re reducing your roof’s exposure to the elements, such as UV light, rain, wind, and snow. Keeping your roof protected can extend its lifespan and keep your home better insulated.
In fact, students at the University of California San Diego found that solar panels actually kept the building’s roof an average of 5°F cooler than an exposed rooftop. This in turn saved the building an average of 5% in cooling costs. With such a significant saving, rooftop solar is becoming increasingly popular.
Rooftop solar is also simpler when it comes to the permitting process. Your blueprints for your home must be submitted to prove your roof’s structural stability. You also need to ensure that all local building codes and regulations are appropriately followed.
The adverse effects of roof-mounted solar systems are often overlooked. Elevation can render them inaccessible, and their positioning can lead to decreased efficiency. Modification and troubleshooting may also be more difficult. Additionally, they may not be suitable for smaller rooftops owing to a lack of space.
If you’re considering installing rooftop solar panels, you need to consider their accessibility; depending on your mobility level and the pitch and material of your roof, you may not want to take the risk of accessing your roof. For example, metal roofing is particularly slippery and more difficult to climb on than other types of roofing.
In addition to considering the accessibility of your rooftop. You may want to think about the overall efficiency of a rooftop system in comparison to a ground-mounted system. As they are typically more difficult to angle correctly due to the existing structure of your roof. They may not be able to capture the same amount of power that a perfectly-aligned ground-mounted system would. This means you may have to buy extra panels in order to reach the power output of your ground-mounted system.
Finally, you’ll need to consider the space constraints of your roof. The average roof area for a standard medium-pitch roof in the US is 1,500 square feet. Not all of this space will be available for use; some areas may be dedicated for other use, such as ventilation and support structures. This means you’ll need to carefully plan the layout of your solar panels around these dedicated areas. As well as existing roof features like valleys, ridges, and dormers. That they can be optimally placed within the available area.
It’s no surprise that rooftop solar is a great choice for homeowners wanting to take advantage of renewable energy. Before you take the plunge and invest in a system, however, there are a few key questions that you need to consider and keep in mind.
First and foremost, check the age of your roof – and if it’s older than five years, look into replacing it. This is for good reason; the lifespan of a roof generally aligns with that of a solar system. So it makes sense to have them installed at the same time. Of course, this isn’t always feasible and depends on the state of your finances. However, consider doing it in order to get the most out of your system.
Another important factor to take into account is any constraints that may be outlined by your Homeowners Association (HOA). In some states, solar access laws may prevent the installation of solar panels. So be sure to check with your HOA before you get too far along with the process. Additionally, should there be any potential problems or roadblocks, try to work out any kinks with the HOA before you have the system permitted.
Lastly, do your research, and determine if your electricity is expensive enough to justify the initial investment. Solar panels are an excellent investment, and you’ll likely make up for your original expenditures in the long run. However, it still costs money upfront, and can take time for the ROI to come in. Make sure that you’re basing your decision on balanced cost-benefit factors.
| Pros of Roof Mounts | Cons of Roof Mounts: |
|---|---|
| Faster installation process | Difficult to access and clean |
| Reduced cost and fewer parts, pieces, and tools required | Troubleshooting can be more challenging |
| Does not take up real estate | Risk of roof damage during and after installation |
| Aesthetically pleasing | The system is confined to the dimensions of the roof |
| Higher panel temperatures can mean decreased energy output |
So when it comes to deciding between a Ground Mount vs. Roof Mount Racking for your solar needs, it’s important to consider all of the factors – cost, convenience, and energy production – and make an informed decision for your living space and your budget.
Ultimately, the choice comes down to what works best for you and your living space. If you have the extra space and budget for a ground mount, there are several advantages to this option. However, if you’re limited on space but have a more flexible budget, a roof mount may be the best route. No matter what you decide between Ground Mount vs. Roof Mount Racking the important thing is to make an educated decision that is right for your individual needs.
