Solar Panel Stand Design

Things to Consider Before Designing a Solar Panel Stand

When designing solar panel stands, the following factors should be evaluated:

Location and Site Analysis

The location and specific site conditions will dictate what type of solar panel stand design is required:

Sun Exposure – Seek to maximize direct sunlight during peak daylight hours. Nearby obstructions like trees or buildings can result in partial shade that reduces output.

Land Space – Ensure there is adequate area for the desired number and layout of solar panels. Adhere to property line setbacks.

Slope/Terrain – A flat or gently sloping, south-facing site is ideal for fixed tilt stands. Use tracking mounts for uneven terrain.

Structural Needs

The stand must be designed to handle all expected structural forces and loads:

Material Strength & Durability – Withstand years of exposure to sun, wind, rain/snow, storms, debris, animals, vandalism, etc.

Anchor Design – Securely anchor stands in the ground while still allowing some seasonal angle adjustability.

Adjustability – Allow for manual seasonal tilt adjustments for optimal sun exposure angles.

Solar Panel Specifications

Design the mounts customized to your specific solar panel model:

Panel Dimensions & Weight – The stand must accommodate the panel shape and support the distributed weight.

Mounting Mechanism – Attach to the panel frame at optimal structural support points.

Wiring Considerations – Enable accessible, neat wiring runs without damage risk.

Applicable Codes and Standards

Ensure solar panel stands adhere to all required codes and standards:

Structural, Electrical, Fire, etc – Meet state and local requirements.

Permitting & Inspections – Have a licensed engineer sign off on designs.

Types of Solar Panel Stands

The choice of solar panel stand depends on several factors, including the location, installation type, and desired functionality. There are 5 common types of solar panel stand systems. Here’s an overview of common stand designs:

  1. Ground Mount

Ground mounts are the most versatile and widely used type of solar panel stand. They consist of poles or posts fixed directly into the ground, providing a sturdy foundation for solar panels. Ground mounts are suitable for both residential and commercial installations on open land.

  1. Pole Mount

Pole mounts are a variation of ground mounts, utilizing a single pole anchored in the ground to support the solar panels. This design is particularly well-suited for installations in areas with limited space or where ground disturbances are undesirable.

  1. Tilt Mount

Tilt mounts introduce an angled design to the solar panel stand, allowing for precise adjustment of the tilt angle to maximize sunlight capture throughout the year. Tilt mounts are commonly used in fixed-axis tracking systems, where the panels are adjusted manually or seasonally.

  1. Tracking Mount

Tracking mounts represent the most advanced type of solar panel stand, incorporating motorized systems that automatically track the sun’s movement across the sky. Single-axis trackers follow the sun’s east-west movement, while dual-axis trackers also adjust for the sun’s altitude changes.

  1. Roof Mount

Roof mounts are designed for rooftop installations, utilizing brackets or rails secured to the roof structure. Roof mounts are space-efficient and aesthetically pleasing, making them a popular choice for residential and commercial buildings.

Material Options for Solar Panel Stands

The choice of material for solar panel stands is crucial for both performance and longevity. Common solar panel stand and mount materials include:

  1. Wood

Wood offers a natural, aesthetically pleasing, and low-cost option for solar panel stands. Cedar and redwood are particularly well-suited due to their natural resistance to rot and decay. However, untreated pine is susceptible to rot and insect damage, requiring additional treatment or protection.

  1. Metal

Metal materials, such as galvanized steel or aluminum, provide superior strength and durability compared to wood. Galvanized steel is particularly resistant to corrosion, making it ideal for outdoor installations. Aluminum offers lightweight and corrosion-resistant properties, but it can conduct heat, which may require additional considerations in hot climates.

  1. Concrete

Concrete stands offer exceptional durability and can withstand extreme weather conditions. However, their significant weight can make them more challenging to install and transport. Additionally, post footings may be required to provide a stable foundation for concrete stands.

Tips to Design Solar Panel Stands for Maximum Efficiency

Follow these best practices when designing solar panel stands:

A. Allow for Seasonal Angle Adjustments

Manually adjustable tilt angle settings by season maximize year-round energy production as the sun’s path across the sky shifts.

B. Select Corrosion-Resistant Materials

Use galvanized, stainless, or aluminum components to withstand decades of sun, moisture, and soil contact without deterioration or seizing up.

C. Optimize Strength While Minimizing Materials

Efficient structural aluminum components and concrete anchoring often outperform wood and steel by mass. Reduce needless use of excess materials driving up costs.

D. Enable Easy Solar Panel Access

Elevating solar panels on poles or tilted legs makes inspection, cleaning, and maintenance much simpler over decades of service.

E. Integrate Wind Bracing

In windy locations, diagonal bracing and concrete ballasting may be needed so wind uplift forces do not damage the structural integrity.

F. Use Quality Components

Higher-grade construction-level mounting hardware, poles, and mechanical components outlast consumer/residential grades, saving replacement costs.

Weight Bearing Capacity of Solar Panels

Solar panel’s self-weight is typically:

  • 4 psf for crystalline silicon panels
  • 2 to 3 psf for thin-film panels

Solar panel racking systems should be designed to withstand:

  • 3 times solar panel weight for wind loads
  • 5 times solar panel weight for snow loads

Consult local structural code requirements as well to establish suitable structural safety factors.

Comparison of DIY and Commercial Solar Panel Stands

Here is a comparison table contrasting DIY and commercial solar panel stands:
