Heat treating and tempering alloys also enhances their strength considerably.
6063 T6 and 6061 T6 tempers provide a good blend of strength, machinability, and corrosion resistance needed for most solar mounting applications.

III. Extrusion Process

Aluminium parts like channels, angles, and tubes for solar mounting systems are primarily made using the extrusion process.

Extrusion Methods

There are two main methods:

Direct extrusion – Material is pushed through a die using a ram.
Indirect extrusion – Material pulled through a die using a stem.

Direct extrusion is more common for larger aluminium sections like solar frame components.

Dies and Moulds

The shape and dimensions of the extruded aluminium profile is defined by the steel die design. Common dies exist for standard rails and channels.

Complex profiles can require custom die fabrication. Proper die heating up to 500°C is needed for smooth extrusion flow.

Billet Preparation

Aluminium billets provide the raw material.
Billets are heated up to 900°C to soften the aluminium for smooth extrusion.
Proper lubrication prevents sticking inside the chamber.

Extrusion Variable	Typical Value
Ram Pressure	15,000 tons
Billet Temperature	750°C to 930°C
Extrusion Speed	5 to 50 ft/min

This allows very customizable aluminium grades and profiles to be created for solar mounting components using the extrusion process.

Ground mounts rely on fixed pole foundations.

Proper selection of durable aluminium hardware ensures long system lifespans.

V. Finishes and Coatings

Aluminium can be given different finishes and coatings to improve aesthetics, protection, and performance.

Anodizing

Anodizing is an electrolytic process that converts the surface to aluminium oxide for enhanced corrosion resistance.

Hard anodizing creates a thicker protective layer but poor wear resistance.
Soft anodizing offers better abrasion resistance.

Anodizing also allows dying the surface in colours like black for an attractive finish.

Powder Coating

Powder coated finishes are commonly applied through:

Surface preparation
Powder application through spraying
Baking to cure the powder

Advantages include:

Highly abrasion resistant
Can produce metallic colour finishes
Environmentally cleaner process

Pre-treatments

Chemical pre-treatments like chromate conversion help cleaning and metal preparation to improve coating adhesion.

Finish/Coating	Application Method	Use
Anodizing	Electrochemical	Corrosion protection
Powder Coating	Spray then bake	Colour finish
Pre-treatment	Chemical cleaning	Improve coating bond

Properly finished aluminium can maintain excellent performance and appearance for solar hardware when exposed to harsh outdoor environments.

VI. Design Considerations

Higher alloy grades enable thinner walls and less material.
But machinability and ductility decrease with stronger alloys.

Wind and Weather

The mounting components must resist:

High wind forces
Snow/ice loads
Temperature swings
Generally wet conditions

Corrosion resistant alloys and coatings are critical.

Vibration Dampening

Uncontrolled vibrations can slowly loosen connections and fasteners over time through metal fatigue.

Structural stiffness tuning using shapes like tubes or ribs help attenuate harmonic vibrations.
Bushings and grommets in mounting hardware also dampen vibrations.

Careful engineering ensures aluminium solar mounting hardware reliability over their ~25 year expected lifespan.

VII. Advantages Over to Other Materials

Aluminium has many benefits compared to other materials for solar mounting construction.

Strength and Durability

Aluminium alloys provide very good strength while resisting corrosion.
Steel is strong but much heavier and prone to rusting.
Polymers are lighter but weaker and degrade under UV exposure.

III. Location and Hemisphere Factors

To optimize the energy generation, seasonal tilt solar mounting systems must adjust panel angles based on location and time of year. The key factors related to geography are:

Hemisphere

The hemisphere where the system is installed determines peak sunlight seasons:

Northern hemisphere – Peak production in summer
Southern hemisphere – Peak production in winter

This impacts ideal tilt strategies.

Country/Region

More specifically, the country and region indicate:

Latitude – Affects sun angle path
Climate patterns – Rainy or dry seasons affect solar availability

Sunlight Exposure

Tilt adjustments maximize sunlight exposure during peak seasons:

Winter – Tilt to maximize lower winter sun angles
Summer – Account for higher summer sun paths

Angles that capture the most sun during peak seasons will generate the greatest additional energy.

Ideal Tilt Angles

Formulas can dial in optimal orientation based on location:

Summer – (Latitude * 0.93) – 21°
Winter – (Latitude * 0.875) + 19.2°

Sensitivity Analysis around these starting points can further maximize yearly yield if seasonal cloud cover data is available.

Properly accounting for site geography informs data-driven tilt strategies that maximize solar utilization potential for seasonal mounting systems. This allows substantial gains in solar energy production on an annual basis.

Seasonal Tilt Adjustments

To maximize power generation, seasonal tilt solar mounting systems must alter their orientation multiple times per year to match the sun’s shifting path across seasons. There are two main approaches:

Half-Yearly Adjustments

Tilt angle can be changed twice a year based on spring/fall equinox dates:

Northern Hemisphere:
Summer tilt – March 20th
Winter tilt – September 22nd
Southern Hemisphere
Summer tilt – September 20th
Winter tilt – March 21st

This better aligns with seasons versus calendar dates.

Quarterly Adjustments

For more precision, adjust tilt 4 times per year aligned to solstices and equinoxes:

Season	Northern Hemisphere	Southern Hemisphere
Summer	June 20th	December 21st
Autumn	September 22nd	March 20th
Winter	December 21st	June 20th
Spring	March 20th	September 23rd

Benefits

Increased energy collection during “shoulder” seasons
Reduced machine downtime for adjustments
Gradual angle changes better track sun’s daily course

Considerations

Additional manual labour required
Possible downtime during adjustments

Data Analysis

Historical on-site solar data can reveal optimal dates and degree days for adjustments. Sensitivity analysis identifies energy gains from extra tilts.

Automated Systems

For large installations, automated actuators can systematically alter tilt. But this adds complexity and capital costs.

Fine-tuning mount orientation to follow the sun’s seasonal movement provides outsized electricity generation gains for minimal incremental effort using seasonal tilt solar mounting systems.
