With all these advantages, it’s no wonder ground mounting structures are becoming the preferred mounting solution for many solar projects. Keep reading to learn more about the different types of ground mounted options available.
II. Strengths of Ground Mounted Setups
Installing a solar panel system on the ground rather than the roof offers some unique advantages. Here are the main strengths of ground mounted setups:
Orientation and Angle Flexibility – With ground mounts, we are having the panels that can be positioned at the optimal angle and directions to maximize sunlight exposure. You are not limited by the shape or direction of the areas on your roof.
Higher Energy Production – The open airflow underneath helps keep temperatures lower. This allows ground mounted panels to convert sunlight to energy more efficiently, generating 10-45% more power.
Easy Maintenance – Accessing rooftop solar panels typically requires climbing ladders or using special equipment. Ground mounts are closer to the ground, making regular inspection and cleaning much simpler.
No Rooftop Restrictions – Rooftop solar projects may be limited by structural issues, vents/chimneys, or lack of space. Ground mounts avoid all the rooftop restrictions.
Land Restrictions – While rare, some neighbourhoods have rules against installing visible solar panels. Ground mounts may need to be hidden behind the fences or vegetation.
III. Weaknesses of Ground Mounts
While ground mounted solar offers significant advantages, there are some potential downsides to consider as well:
Higher Installation Cost – In general, a ground mounting system has a higher upfront price tag than an equal sized rooftop system. The racking and foundation materials, digging/trenching, and labour make it more expenive.
Land Restrictions – Although rare, some neighbourhoods prohibit visible renewable energy systems or restrict their placement. Ground mounts may need creative vegetation or fencing.
Safety Concerns – Since panels are accessible, a ground mounting structure poses a minor risk for kids or pets walking into them. Proper fencing helps mitigate this.
Damage Risks – Rooftop solar is largely protected from incidental damage. However, ground mounted panels may be exposed to vehicles, animals, weather events, vandalism etc.
Aesthetic Impact – Low profile ground mounts usually blend into landscapes well. But some systems stand out and homeowners may prefer to keep their yard/lawn view unchanged.

IV. Types of Ground Installations
If you decide to install the ground mounted solar system, you have several options when it comes to the specific type of mounting structure. The three main types of ground installations are:
Traditional ground-mount
Tracking systems
Carports and canopies
Traditional ground-mount systems use to anchors and robust structural racking to fix panels in an optimal position. This is the most common type of ground mounted system.
Tracking Systems go by step further by using automated hardware to move panels and follow the sun’s path during the day. This further maximizes energy production but has a higher cost. Single-axis trackers shift panels east-west or north-south to capture more sunlight. More advanced dual-axis trackers can shift in multiple directions to keep panels perpendicular to the sun’s rays.
Carports and Canopies utilize very large Ground Mounted Structures as coverage for vehicles in parking lots or other uses. For example, a solar carport can provide shade for cars while generating clean power.

Determine the scale of your solar needs and budget to decide which type of ground installation makes the most sense. Tracking systems produce a good amount of extra energy but carry a cost premium over traditional fixed racking.
V. Traditional Ground-Mount Systems
The most common and cost-effective type of ground mounted solar setup is the traditional fixed racking system.
Traditional ground-mount systems work similarly to rooftop mounts. Panels get attached with the strong metal frame and angled to optimize sun exposure. Instead of being installed on singles though, the racking frame mounts directly into the ground with the pier or anchor supports.
Benefits of traditional fixed ground mounting:
Low Cost – Traditional mounts have the lowest hardware and installation the costs per watt over other ground systems. This makes it affordable for most homeowners.
Easy to Install – For most residential sites, traditional fixed mounts can be fully installed in 1-3 days with a small crew minimizing labour expenses.
Low Maintenance – With no moving parts or motors, traditional systems require very little ongoing maintenance besides occasional panel cleaning.
Expandable – Additional panels can be easily added later on to increase your system size. The fixed mounting structure is designed for modular expansions.
The simplicity, affordability, and reliability of fixed position ground mounting structures make them a top choice. The only downside is they lack the sun tracking advantage of more complex systems. But the better return on investment keeps traditional mounts popular for residential installs.
VI. Tracking Systems
Tracking systems take ground mounted solar technology to the next level for maximum sunlight capture and energy production. These systems utilize motors, sensors, and controlers to automatically move solar panels over the course of a day. By keeping panels aligned perpendicular to the sun’s rays, they generate up to 45% more power annually.
There are two main types of solar trackers used with ground mounts:
Single-Axis Trackers: Rotate panels along one axis to follow the sun east to west.
Dual-Axis Trackers: Rotate panels along two axes enabling full 360 degree range of motion to precisely face the sun all day.
Benefits provided by tracker ground mounting:
Greatly increased energy yield per panel
Optimized spacing between rows of panels
Better performance in winter months
Reduced shade impact
The main disadvantages of using solar trackers are higher hardware costs, more complex installation, and increased maintenance requirements. Trackers utilizes motors, controllers, wiring, and gears that may eventually need replacement. Proper installation is also key for reliability.
Overall, the pros of solar tracking capabilities often outweigh the extra costs for larger commercial ground mounting projects. The significantly higher energy production provides better and faster return on investment. But trackers may be excessive for smaller residential ground installs where fixed mounts sufficient.
Carports and canopies utilize very large ground mounting structures that serve dual purposes. They provide shade or shelter, while also hosting solar panels to generate significant amounts of the electricity.
The most iconic example is the solar carport. As the name suggests, solar panels get installed on the roof structure of a carport. This keeps vehicles underneath shaded from the elements, while the panels above soak up the sunlight. The collected energy can then power buildings, electric vehicle charging stations, or get fed back into the grid.
Solar canopies function similarly, by mounting panels on top of a steel structure designed specifically for shade. You often see these utilized in parks, schools, and playgrounds to produce renewable power in addition to shielding what’s underneath.
Benefits of solar carports and canopies:
Large open spaces for mounting many panels.
Dual purpose installations (power + shelter).
High visibility demonstrations of clean energy.
The main barriers to larger carport or canopy projects have traditionally been the high upfront design and material costs. However, as solar panel prices continue to fall, these types of installations are becoming more financially viable. And they serve as impactful sustainability symbols for schools, commercial centres, and other public spaces.
Installing a ground mounted solar array comes at a higher initial price tag than rooftop solar. There are several cost factors that contribute to this:
Structural Materials – Industral grade aluminium and galvanized steel is used to assemble the racking, poles, and foundations. These materials are more heavy duty than typical rooftop mounts.
Excavation And Equipment – Digging holes for foundations, trenching electrical wires, renting heavy machinery, and transporting materials add to project costs.
Labour – Ground mount installations take longer and often require crane equipment to position modules. More man hours equals more labour expense.
However, against these higher upfrontcosts are the long term savings:
Increased Energy Production – The optimal positioning and solar tracking capabilities lead to significantly more clean energy generated.
Accelerated depreciation further reduces tax burden.
Over time, the extra energy and financial incentives make ground mounted systems pay for themselves more rapidly compared to equivalently sized rooftop installs. And protection from weather/debris means savings on roof repairs.
IX. Maintenance of Ground Mounted Solar
A key advantage of ground mounted solar is that regular maintenance is easier than rooftop systems. Accessing panels on the ground avoids the need for ladders or technical rope training. Basic upkeep best practices include:
Inspections
Inspect all wiring, mounts, gear boxes for damage quarterly. Repair any loose connections or corrosion.
Check panel glass for cracks/chips annually which could allow moisture damage.
Cleaning
Clear any accumulated leaves/debris around the mounting structure.
Wash panels with soft brushes and water at least twice per year for maximum solar absorption.
Vegetation trimming
Trim any nearby plants/branches that may overhang and put panels in shade. Sunlight occlusion severely reduces output.
Snow Removal
Use non-abrasive plastic shovels to clear heavy snow off panels after storms.
Tracking & Monitoring
Ensure tracker motors function properly in all seasons.
Monitor production output levels monthly to catch any decreased yields from common culprits like dirty panels, tracking miss collaboration, or wiring issues.
Following this basic preventative maintenance checklist for your ground mounted system improves reliability, extends equipment lifespan, and maximizes solar energy production year after year.
X. Conclusion
Installing solar panels on the ground rather than roofing provides unique advantages. Ground mounted solar gives you flexibility on placement for optimum sunlight exposure for leading to significantly higher energy generation. The ability to incorporte tracking systems takes this productive potential even further.
As solar panel and storage prices continue falling, renewable energy adoption will only accelerate further. Both rooftop and ground mounted solutions each have ideal applications depending on the site constraints and power demands. Consult with qualified solar professionals to map out the best clean energy generation plan tailored for your home or business.
I. Introduction to Solar Mounting Structure Design
Structura Metal provide a solar mounting structure is a crucial component of any photovoltaic (PV) system installation. Furthermore, this structures purpose is to securely anchor the solar panels while distributing weight and allowing us to orient the panels at the optimal angle to maximize solar radiation capture.
When designing solar mounting structures, we must make the following key considerations:
Building Specifications – age, roof type/condition, location.
Climate Conditions – wind, snow loads.
System Size and Components – number of panels, foundations.
Accessibility for installation and maintenance.
Safety standards and certifications.
There are two main categories of solar panel mounting structures are: Rooftop Mounting Structures
Rooftop mounts support themselves using the building itself and are generally a lower-cost solution. Sub-types include:
Rail-Based – panels clipped onto rails bolted into roof
Rail-Less – panels bolted directly into roof
Shared-Rail – rails are shared between panels
These can be used on both sloped and flat rooftops.
Ground-Based Mounting Structures
Ground mounts require foundations but allow more flexibility. Types include:
Pole Mounts – structure with vertical pole anchored in concrete
Foundation Mounts – vertical posts fixed in excavated foundations
Tracking Mounts – structures with 1 or 2 axis tracking

The mounting structure are also relies on the components like rails, brackets, anchors, and foundations to secure the panels.
II. Rooftop Mounting Structures
Rooftop solar mounting structures attach directly to the roof surface, which helps to distributes weight and reduces costs by utilizing the existing structural support. The main types of rooftop mounts are:
Rail-Based Mounting – Solar panels mount onto the rails that bolt into the roof. This is one of the most common rooftop solutions.
Rail-Less Mounting – Panels bolt directly to the roof without rails. This reduces materials but requires more skill to install.
Shared-Rail Mounting – Solar panels share common rails to reduce rail usage.
Rooftop mounts work for both sloped roof tilted designs and flat roof systems like commercial buildings.
Ballasted Footing Mounts made of concretes blocks help anchor flat roof structures without roof penetration. For pitched roofs, rail-based mounts orient panels at slopes matching the existing roof, while rail-less systems mount the panels in flexible tilted angles.

Pole mounted solar affordably meets growth through phased buildouts. The independent infrastructure allows customizing improvements over time, avoiding full roof replacements. Strategic options like trackers, storage and EV charging reduces environmental impacts even further.
X. Comparison to Ground Mounts
Pole mounting differs from ground mounts in four key ways:
Pole mounts elevate panels higher off the ground for improved solar exposure.
Less land area required for poles versus extensive ground mounting racks.
Pole mounts sustain higher wind loads with smaller foundation footprints.
Adjustability possible by tilting pole mounts to optimize angles.
The ideal residential or commercial solar installation leverages the strengths of both mounting approaches. A solar provider can advise the best system design and mounting method for your property.
