    Invention Addressed a Major Gap In Prior Art

Abstract / Short Description (Simplified for Non-Experts)

This invention is a solar panel mounting system that automatically moves solar panels in two directions so they continuously face the sun throughout the day and across seasons.

The system uses a simple mechanical linkage with sliding beams and support struts to tilt the panels north-south and rotate them east-west using controlled linear motion from actuators. This avoids complex gears and heavy rotating structures used in conventional dual-axis trackers.

As a result, solar installations can capture more sunlight and generate more electricity while using a lighter, easier-to-maintain structure suitable for large solar farms.

Problem the Invention Addresses

Solar panels generate the most electricity when sunlight hits them directly. However, the sun’s position changes constantly:

  • During the day — moves from East to West
  • During the year — shifts North to South due to seasonal changes

Because of this movement, most solar installations cannot maintain the ideal angle all the time.


Limitations of Existing Solutions

1. Fixed-Tilt Systems


  • Panels are installed at a single angle
  • Easy and low cost, but large energy loss occurs for most of the day
  • Significant reduction in annual power generation

2. Single-Axis Trackers (Common Industry Standard)


  • Panels move only East-West (daily movement)
  • Cannot adjust to seasonal sun position
  • Performance drops during winter and seasonal transitions
  • Plants do not reach maximum energy yield

3. Conventional Dual-Axis Trackers


  • Can follow the sun in both directions
  • Provide high energy output
  • However:
  • Mechanically complex
  • Heavy structures
  • Expensive gearboxes and drive systems
  • High maintenance requirements
  • Difficult to scale for large solar farms


Resulting Challenges for Solar Developers

  • Lower electricity generation than possible
  • Reduced return on investment
  • Higher land usage per MW installed
  • Increased cost of energy (LCoE)
  • Mechanical failures and maintenance in complex trackers

In simple terms:

Solar plants must choose between affordable systems that waste sunlight or efficient systems that are too expensive and complicated to deploy at scale.


The Invention — Solution to the Problem

The patented invention provides a practical dual-axis solar tracking system that allows solar panels to follow the sun both daily (East-West) and seasonally (North-South) using a simple mechanical structure instead of complex rotating machinery.

Instead of rotating the entire panel structure with heavy motors and gearboxes, the system converts straight-line (linear) movement into controlled angular motion. This is achieved through a four-bar linkage mechanism made of beams, struts, and supporting pillars.

How the Solution Works

The system uses two coordinated motions:

1. East–West Movement (Daily Sun Path)


  • A sliding upper beam moves in a straight line
  • This motion is transferred through flexible brackets and bearings
  • The solar panels rotate to follow the sun from morning to evening

2. North–South Tilt (Seasonal Sun Shift)


  • A lower sliding beam moves between support pillars
  • Connected struts convert the sliding motion into frame tilting
  • Panels adjust angle for summer and winter sun positions

Both movements are powered by actuators and can be controlled automatically by a controller.


Key Concept Behind the Innovation

The invention replaces:


  • Torque tubes
  • Gearboxes
  • Large rotating shafts
  • Complex multi-motor systems

with a balanced linkage geometry that moves many panels using minimal force.


What Makes This a Practical Industry Solution

The system achieves dual-axis tracking while keeping the structure simple and scalable:

  • Linear motion instead of heavy rotational drives
  • Fewer moving parts
  • Ability to move multiple panels with one actuator
  • Easy installation and transport
  • Stable under wind forces
  • Suitable for large solar farms

Commercial Outcome

This invention solves the industry trade-off by delivering:

High energy capture (dual-axis performance) + low mechanical complexity (single-axis practicality)

As a result, solar plants can generate more electricity without adopting expensive or maintenance-heavy tracking systems, improving overall project economics and scalability.



The Gap in Existing Technologies

Prior solar tracking technologies fall into two separate categories, each with critical limitations:

1. Single-Axis Trackers

  • Track the sun only from East to West (daily movement)
  • Do not adjust for seasonal North-South sun position
  • Result: noticeable loss of energy generation, especially during winter and seasonal transition periods

2. Conventional Dual-Axis Trackers

  • Track both daily and seasonal movement
  • Provide higher energy output
  • However:
  • Require complex rotating structures
  • Use heavy torque tubes, gear drives, and multiple motors
  • High manufacturing and installation cost
  • Difficult maintenance
  • Limited scalability for large solar farms

The Industry Gap

There has been no practical system combining:

  • Dual-axis energy performance
  • with
  • Mechanical simplicity and cost efficiency suitable for utility-scale deployment

In other words, the market had to choose between:

  • Affordable but lower-yield systems, or
  • High-yield but commercially impractical systems

How the Invention Fills the Gap

The patented system introduces a four-bar linkage mechanism that converts linear actuator motion into panel rotation and tilt.

This enables dual-axis tracking without heavy rotating machinery or complex drive assemblies.

Result:

A commercially deployable solution delivering near dual-axis performance using a simpler, lighter, and lower-cost mechanical architecture.

Conclusion

The invention closes a long-standing industry gap by making dual-axis tracking economically and mechanically practical for large-scale solar installations — something prior art systems were unable to achieve.
