    Invention Addressed a Major Gap In Prior Art

Overview

The invention relates to a solar panel mounting system that automatically follows the sun’s position throughout the day and across seasons.

Problem

Conventional fixed-tilt structures and common single-axis trackers cannot keep solar panels aligned with the sun at all times. This reduces energy generation, especially during seasonal changes. Traditional dual-axis trackers improve performance but are often heavy, complex, and expensive to deploy at large solar plants.

Solution

The patented system introduces a simplified dual-axis solar tracking structure that adjusts panel orientation in two directions using a mechanically efficient linkage and actuator arrangement, providing higher energy capture while remaining practical for large-scale installations.

Key Features


  • Two-direction tracking (daily east-west and seasonal north-south movement)
  • Four-bar linkage mechanism converting linear motion into rotation
  • Rail-beam and strut based movement instead of heavy gear systems
  • Microcontroller-based automatic sun-tracking control
  • Modular structure designed for ground-mounted solar farms

Benefits


  • Increased energy generation compared with fixed or single-axis systems
  • Lower mechanical complexity than conventional dual-axis trackers
  • Reduced maintenance and installation cost
  • Suitable for utility-scale solar projects

Claim-Based Protection

The patent protects the structural arrangement of beams, struts, joints, and actuators that enable controlled dual-axis movement of solar modules using a simplified mechanical linkage system.


The Problem the Invention Addresses

Solar panels generate the most electricity when they directly face the sun. However, the sun’s position constantly changes — it moves across the sky during the day and shifts north-south across seasons throughout the year. Most solar installations cannot continuously maintain the best angle toward the sun.

Today, the industry mainly uses three types of mounting approaches:


  1. Fixed-tilt structures
  2. Panels remain at one angle all year.
  • Simple and low cost
  • But they lose a large amount of potential energy because they are rarely aligned with the sun
  1. Single-axis trackers (commonly used in utility solar plants)
  2. Panels rotate only east-west during the day.
  • Improves generation compared to fixed systems
  • Still inefficient during mornings, evenings, and seasonal shifts (winter vs summer)
  1. Traditional dual-axis trackers
  2. Panels follow the sun in both daily and seasonal directions.
  • Best energy output
  • However, they are mechanically complex, heavy, expensive, and difficult to maintain at large scale

Because of this, solar developers face a major trade-off:


  • Affordable systems → lower energy output
  • High-performance systems → too costly and complicated

As solar tariffs decline worldwide, projects must produce more electricity per installed megawatt to remain financially viable. The industry needs a solution that delivers near dual-axis performance without the cost, weight, and maintenance burden of conventional dual-axis machines.

In simple terms:

There is no practical system today that combines high energy generation with low mechanical complexity and scalable cost. This gap directly impacts project profitability, land usage efficiency, and long-term operational reliability in large solar farms.

The invention is designed specifically to solve this performance-versus-cost conflict.



The Invention — The Solution to the Problem

The invention provides a mechanically simplified dual-axis solar tracking system that automatically keeps solar panels aligned with the sun throughout the day and across seasons, while remaining practical for large-scale solar installations.

Instead of using heavy rotating platforms, complex gearboxes, or large torque tubes like conventional dual-axis trackers, the system uses a smart structural arrangement that converts simple linear movement into controlled panel rotation.

How the Solution Works

The solar modules are mounted on a frame supported by ground-fixed pillars. Two independent movements are created:

  1. East-West (daily sun movement)
  2. A rail beam and actuator move linearly and rotate the module frame horizontally so the panels follow the sun from morning to evening.
  3. North-South (seasonal sun movement)
  4. A second rail beam connected through struts adjusts the tilt angle of the frame, allowing seasonal alignment as the sun shifts across the year.

These motions are achieved through a four-bar linkage mechanism, which transforms actuator motion into smooth angular movement. Spherical joints allow flexibility and maintain alignment even on uneven terrain.

A microcontroller-based control system automatically positions the panels using programmed solar path calculations. Multiple tracker rows can be synchronized, reducing control and drive complexity.

Key Characteristics of the Solution

  • Dual-direction tracking using simple linear actuators
  • Mechanical linkage replacing complex rotating machinery
  • Balanced structural geometry for stability
  • Modular construction suitable for large solar farms
  • Automatic sun-tracking control

Result

The invention delivers the energy-capture advantages of dual-axis tracking while avoiding the cost, weight, and maintenance challenges that previously prevented widespread deployment at utility scale.

In practical terms, it bridges the gap between low-cost single-axis trackers and high-performance dual-axis systems by combining improved energy yield with scalable installation economics.

The Gap in Prior Art

Existing solar mounting technologies force project developers to choose between performance and practicality:

  • Fixed-tilt systems
  • Low cost and simple, but large energy losses because panels cannot follow the sun.
  • Single-axis trackers (industry standard)
  • Track the sun only during the day (east–west).
  • They still lose substantial energy during mornings, evenings, and seasonal changes when the sun’s height varies.
  • Conventional dual-axis trackers
  • Provide the best energy output by following the sun in both directions.
  • However, they rely on heavy rotating structures, gear mechanisms, and complex drive systems.
  • As a result, they are:
  • Expensive to manufacture and install
  • Difficult to maintain
  • Structurally heavy and less reliable for large solar farms

Because of these limitations, dual-axis tracking has not been widely adopted at utility scale despite its energy advantage.

The Missing Solution

The industry lacked a system that could:

  • Deliver near dual-axis energy performance
  • Maintain mechanical simplicity
  • Be cost-effective for large solar plants
  • Reduce maintenance and structural complexity

How the Invention Fills the Gap

The patented system introduces a structurally simplified dual-axis tracker using a linkage-based mechanism and linear actuation instead of complex rotating machinery. This enables dual-direction solar alignment while remaining practical and scalable for commercial deployment.

In short:

The gap was the absence of a commercially viable, large-scale dual-axis tracking solution combining high energy yield with manageable cost and mechanical simplicity — which this invention directly resolves.
