Solar Ground Mount Structure – Top Things to Know About

December 23, 2023

by Jaya with No Comment Generic

I. Introduction to Ground Mounting Structures

In Structura Metal a ground mounted setup refers to a solar panel system that is installed directly into the ground rather than on a roof. Ground installations have become increasingly popular for both residential and commercial solar projects. There are several key benefits that the ground mounts provides over rooftop solar systems:

More flexibility in panel placement.
Increased energy production.
Easier maintenance.
Avoid roof obstacles and structural issues.

At Structura Metal Ground Mounted Solar offers much more flexibility in where you can place panels to optimize sun exposure. With a rooftop system, you are also having limitations for the shape and directions of the areas available. Ground mounts allow placement in the wide open spaces without blocking the sunlight.

In addition, we also having the open airflow beneath ground mounted panels helps to keep the temperatures lower. This allows for more efficient energy conversion and increased energy production compared to rooftop systems. Studies show ground mounted solar can produce 10-45% more energy than the fixed rooftop setups.

Benefits	Ground Mounted Solar	Rooftop Solar
Flexible placement	✅	❌
Increased production	✅	❌
Lower temperatures	✅	❌
Easy maintenance	✅	❌

Furthermore, a ground mounting system avoids any roof structural issues or the obstacles like vents, chimneys etc. And since panels are more accessible on the ground, overall maintenance is simpler without working from heights or ladders.

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.

Weakness	Risk Level	How to Mitigate
Cost	High	Get multiple installer bids to reduce price
Land rules	Low	Petition for renewable energy exceptions
Safety	Low	Add fencing around solar system
Damage	Low	Add protective barriers as needed
Aesthetics	Low	Use vegetation to hide/blend system

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.

System Type	Cost Level	Maintenance	Ideal For
Traditional	Low	Low	Most installs
Tracking	High	Medium	Large installs
Carports	High	Low	Commercial

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.

VII. Carports and Canopies

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.

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.

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

Mount Type	Pros	Cons
Rooftop	Lower cost <br> Use existing structure	Limited panels <br> Roof condition dependent
Ground	More panels <br> Flexible layout	Higher cost <br> Site prep required

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.

Type	Description	Considerations
Rail-Based	Panels clip onto roof-bolted rails	Most common <br> Easy to install
Rail-Less	Direct panel roof mounting	Lower cost <br> Requires skill
Shared-Rail	Panels share common rails	Reduces rails <br> Optimizes installation
Ballasted	Concrete block anchors	No penetration <br> For flat roofs

Proper Mounting Structure Design distributes panel weight, resists wind/weather elements, and orients panels properly on the roof.

III. Ground-Based Mounting Structures

Ground-mounted solar structures are anchored into the ground itself, providing more flexibility than rooftop solutions. Key types of ground mounts include:

Pole Mounts – A simple steel pole and concrete anchor drilled into the ground can support smaller solar panel installations.
Foundation Mounts – Vertical posts or pipes are fixed in concrete foundations requiring excavation and soil analysis.
Tracking Mounts – Structures with the integrated 1 or 2 axis tracking capability to optimize solar radiation capture.

Multi-pole Mounting utilizes multiple vertical pipe supports to extending in a horizontal line to allow the scaling of larger installations.

The Smart Flower is a compact new solution resembling an opening flower with the integrated tracking solar “petals” for high efficiency generation.

Type	Pros	Cons
Pole Mounts	Lower cost <br> Simple install	Small systems <br> Soil dependent
Foundation Mounts	Larger systems <br> Adjustable tilt	High cost <br> Site prep required
Tracking Mounts	Increased energy yield <br> Automated sun tracking	Complexity <br> Higher cost

With ground mounting, factors like soil conditions, wind loads, and frost line depth inform needed foundation specifications. Integrated cable trays and wire runs should also be incorporated into the structural design.

IV. Mounting Structure Components

In addition to the main structure frames, solar mounting systems rely on components like rails, brackets, clamps, and anchors to secure panels and transmit loads.

Rails & Strut Channels – Horizontal rail structures and strut channels, often aluminium or galvanized steel, provide intermediate support and panel mounting points.
Brackets – Adjustable bracket structures attah to rails to angle panels at the optimal tilt.
Clamps – End and mid-clamps tightly affix panels along their edges and prevent slippage.
Anchors & Foundations – Ground screws, anchor bolts, concrete piers and more keep the mounting frame fixed in place.

Wiring trays and cable management components are also integrated into the composite mounting unit.

Component	Composition	Purpose
Rails	Aluminium, steel	Panel support & mounting points
Brackets	Stainless steel	Secure and tilt panels
Clamps	Aluminium	Grip panel edges
Anchors	Galvanized steel	Fix structure to roof or ground

Proper specification and structural analysis ensures components can withstand anticipated wind, snow loads and thermal stresses across the system’s life.

Regular re-torquring of bolts and monitoring of components for issues like corrosion is key for longevity.

V. Structural Considerations

Careful analysis of building specifications and site conditions informs the customized structural design of solar mounting systems. Key factors include:

Building Age & Type – The roofing substrata must have sufficient integrity to withstand panel loading. Older or weaker structures may have lower weight tolerances.
Roof Accessibility – Installers will require safe access routes to the roof location that can accommodate components and tools.
System Layout – Allowances must be made for positioning of all structural elements, panels, inverters and related components.
Shading – Nearby structures or roof elements that could cast shadows on panels should be considered.
Weather Loads – Snow, wind and rainfall levels determine design wind and snow load requirements.
Soil Conditions – For ground mounts, soils must be evaluated for suitability to anchor foundation components.

Consideration	Factor	Effect
Building Type	Material strength <br> Roof pitch	Weight limits <br> Mounting options
Accessibility	Pathways <br> Safety	Installation <br> Maintenance
Shading	Nearby structures <br> Roof elements	Solar interruption

Analysis software models these parameters to tailor optimized, code-compliant mounting structural specifications.

VI. Analysis and Reporting

Detailed structural analysis and reporting ensure solar mounting systems meet safety and performance standards throughout their 25+ year lifetimes.

Software Modeling like STAAD analysis the building specs, layouts, component ratings and environmental factors to engineer code-compliant mounting specifications.
Structural Reports document all structural design elements, recommended hardware specifications, layouts, and electrical component integration guidance.
Installation Manuals provide step-by-step mounting and wiring instructions for field implementation.

Deliverable	Contents	Value
Structural Report	Specifications <br> Layouts <br> Hardware details	Customized design basis
Installation Manual	Mounting instructions <br> Electrical layouts	Correct field implementation

Through reporting and guidelines empower the proper system installation and inform ongoing maintenance requirements like bolt re-torquing for maximum safety and energy production.

In trapezoidal mounting system the versatility of mounting brackets makes them an ideal solution for residential and commercial trapezoidal roof solar projects. Their height flexibility and ability to integrate with leading rail and panel systems reduces installation labor and ensures an optimized, secure panel fit. As solar access expands globally, mounting brackets have become a contractor-preferred best practice for metal roof applications.

X. Delta Triangles

Delta triangles are an exceptional solution for elevated solar panel mounting on trapezoidal and corrugated metal roofs. Their adjustable tilt angle and compatibility with leading rail systems enables optimized solar capture.

Key advantages of delta triangles:

Installation at tilt angles from 5° to 45°
Position and size of solar array is variable
Orientation towards eaves or verge possible
Ideal even for small, 1-panel systems
Low shipping cost due to collapsible design

How Delta Triangles Work

Delta triangles have a triangular frame that sits atop roof seams, secured directly using sheet metal screws. The triangles pivot to adjust tilt angle to the ideal degree for solar exposure.

Trapezoidal sheet metal rails then attach to connect the triangle to the roof seem. The panels themselves mount to the rails using end clamps and mid clamps.

Cross adapters join the upper rail to the triangle base, enabling a secure structural connection.
