by Jaya with No Comment Generic

I. Introduction

Hanger bolts are an essential component of solar mounting systems installed on rooftops. They serve as the structural attachment between the solar panels and the roof surface.

Hanger bolts consist of:

A threaded bolt
Collar nuts and washers
An EPDM rubber grommet seal
A mounting plate with a slot

They are made of durable stainless steel and aluminum.

The key characteristics of hanger bolts include:

Feature	Description
Adjustability	Offer variable lengths and angles to mount panels
Structural integrity	Withstand wind, weather and meet building codes
Watertight sealing	Rubber gasket protects roof from leaks

Hanger bolt kits contain all the fittings needed for a complete solar panel installation:

Hanger screws
Mounting rails
Mid/end clamps

We provide a secure and user-friendly mounting system with professionals and DIY installers.

When paired with compatible solar racks and rails, hanger bolt sets enable angled or flat installations on various roof types like singles, tiles, and metal roofing profiles.

By elevating and securely fastening solar modules, hanger bolts play a critical role in durable and high-performing rooftop solar energy systems. Their adjustable nature allows for tailored positioning to maximize solar capture potential.

II. Components

Hanger bolt solar mounting systems comprise three main components that work together:

Hanger Bolts

Hanger bolts are the metal fasteners that attach solar panels and rails to the roof structure. Key features include:

Threaded stainless steel shaft
EPDM rubber grommets for water sealing
Flange nuts to secure installation
Lengths ranging from 7″ to 10″

The function as adjustable “hangers” on the roof to position and elevate PV modules at the optimal tilt and angle. The bolt inserts into a pre-drilled hole in the roof while the gasket provides a tight, weather tight connection protecting roof layers underneath.

Adapter/Mounting Plates

These square adapter plates act as the intermediary between the hanger bolt and solar rail system:

Made of stainless steel/aluminum
Slotted holes for adjustability
Locks into hanger bolt teeth

The plate height is adjustable on the hanger bolt to achieve proper rail height before being locked into place with collar nuts. This flexibility facilitates customized positioning.

Roof Attachments

On the underside of the roof, these pieces distribute structural loads:

Washers
Support plates with bolt holes
Solid blocking within roof framing

The arrangement securely anchors the system while protecting roofing materials from excessive loads. This allows the solar panels’ weight to transfer safely from the rails through the hanger bolts into the roof framing via these supportive attachments.

Combined together, these three modular solar mounting system components provide robust structural capabilities for rooftop solar installations.

East- West Facing Solar Mounting System

January 13, 2024

by Jaya with No Comment Generic

I. Orientation Options (East-West Mounting System)

In our system we used this for Solar panels in photovoltaic (PV) systems can be mounted in different orientations to the optimize the sunlight exposure. The two main options for orienting solar panels are:

Traditional north/south orientation:
In the northern hemisphere, panels typically face south
In the southern hemisphere, panels typically face north
This allows panels to get direct sunlight exposure throughout the day
East-west orientation:
Panels are arranged with the half facing east and the half facing west
Allows panels to be positioned back-to-back to optimize the space

A. Benefits of east-west orientation:

Improves power density – more panels can fit per roof area
Increases total power production
Easier installation and configuration on many rooftops
Reduces impact of wind pressure on panels
Layout can be optimized for the smaller sites

B. Comparisons:

Orientation	Power Density	Total Power	Ease of Installation	Wind Resistance	Site Optimization
North/South	Medium	High	Difficult	High	Limited
East/West	High	Medium/High	Easy	Low	High

Our team analyise the north/south orientation maximizes total power production, east-west configurations allow for easier installation, greater site optimization, and higher panel density – making them suitable for space constrained commercial sites. Project developers should consider these orientation options to select the best fit.

II. Power Production & Density

Accordingly, adopting an east-west panel configuration can lead to improvements in both total power production and power density compared to traditional north/south facing systems.

A. Improved Overall System Power

We orient our module mounting by positioning panels perpendicular to the roofline. East-west arrays enable modules to place very close together without any clearance issues for shade. This denser layout allows us to install more panels per the area of roof.

With more panels, the overall wattage and energy generation increases substantially. East-west systems can achieve power production improvements of:
5-10% over regular north-facing tilted racks
20-25% over flat roof systems
Although the peak output per panel is lower than ideal tilt south arrays, the total aggregate output is still significantly higher.

B. Higher Power Density

Our system provide greater total power, east-west panels maximize the number of modules per square foot or meter. This is extremely beneficial for:

Land constrained sites
Commercial rooftops with limited surface area
Maximizing a project’s ROI

Space constraints rather than demand constraints usually limit commercial projects. Power density improvements have major advantages.

By packing modules tightly together longitudinally, designers can fit more wattage into the roof orientation “with the grain”.

C. Power Density Increases

System Type	Modules per Area	Power per Area
Flat Roof	Low	Very Low
Tilted South	Medium	Medium
East-West	High	High

In situations where roof or land availability is the limiting factor, prioritizing density over peak generation makes financial sense. Our East-west mounting uniformly excels in this area.

III. Cost Effectiveness

The Structura Metal performance the advantages of east-west solar mounting systems provide significant cost savings in several areas:

A. Easier Installation & Maintenance

Positioning modules in line with the roof rather than perpendicular to it simplifies logistics for installers.
Less custom mounting, racking, and flashing required
Conducting ongoing service and panel cleaning is also easier without tilting modules at difficult angles.
This improves uptime and reduces lifetime operational costs.

B. More Modules per Roof Area

Higher module density unlocks major financial benefits:
Reduces soft costs per watt like permitting, inspection, etc.
Lowers investor risk
Increases resale value
We can preserve the surface area to add solar capacity later.

C. Material Savings

Aligning modules along the roof requires fewer racking and rail components.
Savings multiply across large commercial installations
Less robust, lighter mounting hardware is needed due to the lower wind shear.
The closely packed layout also creates beneficial shading to reduce solar heat gain.

D. Cost Savings

Area	Estimated Savings
Installation Labor	10-15%
Maintenance	5-10%
Soft Costs	10-20%
Racking/Rail	5%

These factors demonstrate why east-west systems make financial sense, especially given their space optimization and generation capabilities.

IV. Configuration & Layout

The specialized configuration and layout of east-west solar mounting systems allow for greater density than conventional options:

A. Back-to-Back Positioning

Modules are oriented perpendicular to the roof ridge
The array is split, with half facing east and the other west
No clearance gaps needed between panel orientations
Enables adjacent rows to be positioned very closely together in a back-to-back arrangement

This unique layout eliminates the spacing requirements imposed by tilting solar modules at an angle or facing multiple directions.

B. Smaller Site Optimization

East-west mounting is especially suitable for optimizing generation on space constrained sites, including:

Rooftops
Land-scarce regions like Germany and Japan
Locations with high property rates

By aligning modules directly with the roof and packing them densely together, this configuration:

Makes full use of the roof surface area
Allows projects to maximize their capacity factor
Carefully balances inter-row shading for smoother power curves

The tight module spacing does require separate electrical architecture for east vs. west strings to prevent mismatches. But with smart design, the gains far outweigh this minor complexity.

V. Panel Orientation

The orientation of solar panels in an east-west array provides complementary advantages over traditional layouts:

A. East and West Facing

The system is to be divided, with half the panels tilted towards the east and the other half facing west.
This unique approach balances morning and afternoon generation:
East modules produce more power as sunrise peaks
West modules catch late daylight as sunset approaches
Having two separate plane orientations smooths the aggregate energy delivery curve.

B. Separate Electrical Systems

Due to their perpendicular angles, the east and the west panel sets cannot be wired together.
Integrating mismatched strings risks equipment damage or reduced output through string clipping.
Instead, the dedicated electrical architectures are used for the east versus west groups.
Each orientation has its own string inverter(s) to aggregate DC power
The AC outputs are combined and fed downstream toward

This specialized design accommodates the dual orientations used in the system. It ensures optimal performance despite the complex interconnections required.

While requiring more planning, the east-west approach ultimately unlocks major efficiency and density benefits in a reliable, robust manner.

VI. Energy Yield

While the peak power production of each panel is lower with east-west orientation, the total annual energy yield is very competitive:

A. Smoothed Generation Curve

East-facing panels generate more electricity in the morning
West-facing panels produce higher output in the late afternoon
This balances overall energy delivery throughout the day
Avoids drastic drop-offs when the sun isn’t directly overhead

B. Peak Output Considerations

Traditional south-facing tilts do maximize solar harvest at solar noon.
This causes a pronounced spike in the output curve.
East-west systems see lower peaks but steadier generation.
Reduces inverter overload risks
Less dramatic ramp-up/ramp-down capacity needs
The aggregate impact is a flatter, more stable feed to the grid.

C. Energy Yield Trade offs

System	Peak Output	Total Energy	Curve Smoothness
South-Facing Tilt	Very High	High	Low
East-West	Medium	Medium/High	High

Consequently, while lagging in peak production capacity, east-west mounting compensates with space savings, density gains, and balanced energy yields. Its smoother output helps grid stability and best aligns solar supply with human energy usage patterns.

VII. Capacity

The high-density east-west solar mounting design unlocks substantial capacity increases per unit of roof or land area:

A. More Modules per Roof

By packing panels tightly together in a space-optimized layout, this configuration maximizes use of the roof print.

Modules aligned longitudinally with ridge
No tilt or clearance gaps between arrays
Back-to-back rows placed very close together

This lets developers dramatically increase the module count and wattages that can fit on commercial rooftop builds.

B. Land Constraints and Capacity

In regions with high population density and scarce open space, east-west mounting packs more productivity into small project sites.

Accommodates more panels vertically and horizontally
Carefully balances inter-row shading
Ideal for countries like Germany and Japan with limited solar footprints.

With minimal adjustments, our mounting systems can securely hold solar panels of any length, width or output capacity. Contact us to build a custom solar mounting solution tailored to your oversized panels.

IV. Managing Panel Load

With solar panels increasing in size, the total panel load from wind and snow also rises. Our mounting systems are engineered to handle these high load conditions.

Calculating Panel Load

We thoroughly analysis expected wind and snow loads based on:

Panel surface area
Installation location
Roof height

This allows us to determine the total forces exerted on the solar panel.

Panel Strength Evaluation

We then evaluate whether the panel structure requires additional reinforcement by:

Comparing total load to the panel’s maximum rating
Considering panel frame, support ribs, and glass strength

Strengthening Options

If needed, we can reinforce the installation through:

Additional mounting points
Shorter span between rails
Switching panel orientation from landscape to portrait

Reinforcement eliminates deflection and firmly secures panels even under heavy snow accumulation or extreme wind speeds.

By carefully evaluating and addressing panel load, we ensure the structural stability, safety, and longevity of large solar installations. Contact us today to analyse your specific site conditions and panel loading.

V. Factors Influencing Panel Output

While solar panel size is important, there are other key factors that impact energy generation:

Panel Structure and Materials

Monocrystalline panels are the most efficient but expensive option
Polycrystalline panels are moderately efficient and affordable
Thin-film panels are cheaper but require more surface area

Higher efficiency panel materials produce more energy from the same amount of sunlight.

Available Roof Space

Carefully measure usable roof sections at optimal angles
Consider shading from trees, chimneys, and other obstacles

More roof space allows the installation of more and/or larger solar panels.

Solar Irradiance and Climate

Sunlight duration and intensity varies by location
Energy demands fluctuate with seasons and weather

Areas with more annual sunlight and temperate climates will generate more solar energy.

While panel size contributes, many other factors influence total energy output. Our experts can help analyze all these variables to design the optimal system for your needs and maximize return on investment.

VI. Determining System Size

Properly sizing your solar system is crucial to meet your energy needs and maximize savings.

Calculate Energy Usage

Review 12 months of utility bills to determine average monthly kWh consumption
account for future needs like electric vehicles
Buy enough panels to cover 100% of usage to eliminate electric bills

Choose Number of Panels

Calculate the kWh output of each panel based on its wattage rating
Divide total energy needs by per-panel production
Size the system to produce excess energy if possible

Consider Electricity Needs

Will grid power be used as a backup or be eliminated completely?
Are there plans to add major appliances or electric vehicles?

Installing more panels than needed ensures all your current and future energy needs will be met.

With your usage data and our panel output expertise, we can determine the optimal solar array size and configuration for your home. Contact us to get started designing a system tailored to your energy consumption.

VII. Installation Considerations

Ground Screws for Solar Arrays

January 9, 2024

by Jaya with No Comment Generic

I. Introduction to Ground Screws for Solar Arrays

Ground screws are an increasingly popular mounting solution for solar arrays, especially ground-mounted solar photovoltaic (PV) systems. As an alternative to concrete foundations, ground screws offer several advantages:

Faster installation times
Reduced costs
Minimal ground disturbance

Helical anchors and ground screws consist of metal piles with screw-like flanges near the tip. They are screwed into the ground using special equipment to provide sturdy anchoring for solar module racking.

The main benefits of using ground screws over traditional mounting methods like cement slabs include:

Less invasive – Requires little excavation or concrete pouring
Reusable – Can be removed and reused if arrays are reconfigured
Faster – Install hundreds of mounts per day vs waiting for concrete to cure
Flexible – Adjustable to uneven terrain; suitable for slopes

When to Use Ground Screws

Ground screws are recommended for:

Solar farms and large-scale ground-mounted installations
Sites with environmentally sensitive areas where minimal ground disturbance is preferred
Areas prone to freezing and thawing which can cause ground shift

They may not be suitable for very rocky areas or soils with large boulders.

Click Here to Learn More

Installation Process

Installing helical piles for solar arrays involves:

Optional soil testing to determine depth
Starting hole excavation if needed
Securing mount to rotary hydraulic drive system
Spinning ground screw to required depth

Equipment needed includes:

Rotary drive system capable of producing high torque
Mounting poles of various lengths
Soil testing tools (for friction and density analysis)

Proper Embedment depth depends on:

Soil density
Frost line depth
Wind and seismic factors

Soil Type	Average Depth
Loose sand	8-15 ft
Compact clay	5-10 ft
Firm bedrock	15-30 ft

Using ground screws for mounting solar arrays can simplify the installation process and reduce overall project costs. Their flexibility and low environmental impact make them an ideal solution for solar farms and ground-mounted PV systems.

II. Types of Ground Screws

There are two main types of screw-based mounts used for anchoring solar arrays:

Helical Anchors/Piers/Piles

Helical anchors consist of a central shaft with one or more helical bearing plates welded near the tip. The spiraling flanges allow them to screw into the soil. Key features:

Come in various lengths to match soil conditions and embedment requirements
Can have single or multiple helical flanges
Available in different shaft diameters and flange sizes
Offer tension and compression capacity

Ideal for: Sandy soils, high water tables

Ground Screws

Ground screws resemble large wood screws with a pointed, threaded tip. The spiraling thread pattern also makes them easy to install.

Sharpened tip can penetrate compacted soils
Threaded design displaces soil rather than removing it
Work well even in rocky areas

Ideal for: Dense or rocky soils

Type	Diameter	Lengths	Torque
Helical anchor	2-6 in	5-20 ft	5,000+ ft-lbs
Ground screw	4-12 in	10-30 ft	8,000+ ft-lbs

Both styles can serve as wind and seismic anchors for solar racking. The choice depends on:

Soil composition at site
Design wind/seismic loads
System size and panel weight

Professional engineers size the ground screws and specify embedment depth based on site soil analysis.

III. Installation Methods

Installation Methods of ground screws for solar arrays

Installing helical piles or ground screws requires specialized equipment to provide enough downward force and torque. Common machinery includes:

Hydraulic rotary drivers – Generate high levels of torque (up to 10,000 ft-lbs) to screw anchors into soil. Some models offer vibration damping.
Power auger drivers – Rotate and push the pile using an internal auger. Allows addition of pipe extensions.
Tracked excavators – Excavators equipped with rotational heads on booms can grip and spin ground screws to depth.

Steps to Install Ground Screws:

Mark screw positions according to engineer plans
Core pilot hole if needed (denser soils)
Position screw at correct angle
Spin screw into ground until proper depth using installed torque values
Level and test installation
Attach solar racking

Other Equipment Needed:

Testing devices – Measure torque values during installation
Leveling tools – Verify proper angle and depth
Compaction tools – Prepare ground surface

For solar farms installing hundreds of anchors, efficiency is important. Multi-screw hydraulic drivers can install 1-2 complete screws per minute in easier soils.

Proper training on machinery is critical to:

Maximize productivity
Ensure reliable, structurally sound installations
Prevent environmental damage

IV. Advantages Over Other Methods

Compared to foundations like concrete piers or I-beams, ground screws offer superior performance for solar installations:

Faster Installation

Install crews can screw hundreds of piles per day
No excavation or concrete curing downtime

Lower Costs

Minimal equipment needs
Small crew size for rapid scaling
No waste removal or concrete expenses
