Self-Powered Pony Module for Solar Tracker Drive and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solar trackers require external power sources for their drive devices and controllers, which can be inefficient and costly, especially in variable terrain installations where energy generation is affected by sun movement.
Innovation Solution
The integration of a pony module within the solar tracker system, where a solar panel powers both the controller and the drive device, allowing for self-sustaining operation and enhanced energy collection through bifacial solar panels that capture light from both sides, thereby increasing energy generation capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If external power sources are used for drive devices and controllers in solar trackers, then the tracker can operate with sufficient power supply, but the system becomes dependent on external power infrastructure which increases cost and complexity
Solution Approach 1:
The pony module enables the solar tracker to power itself by capturing solar energy through its dedicated solar panel and storing it in an integrated battery, eliminating dependence on external power sources. The system serves its own power needs through self-charging capability during daytime operation.
Solution Approach 2:
The pony module combines multiple functions into a single integrated unit: solar panel for energy capture, battery for energy storage, and power supply for driving the tracker. This merging of power generation, storage, and distribution functions into one compact module reduces overall system complexity.
2Productivity
If conventional solar panels are used that only capture light from one side, then the structure is simpler, but energy generation capacity is limited especially during variable weather conditions
Solution Approach 1:
The pony module utilizes bifacial solar panels that capture light from both the front and back surfaces, effectively adding a second dimension of light capture. This allows the panel to generate electricity from direct sunlight on the front side and reflected or diffuse light on the back side, significantly increasing energy generation capacity.
3Duration of action of moving object
If the solar tracker operates without integrated power storage, then the device complexity is reduced, but the operation time is limited and the tracker cannot function during periods without sunlight
Solution Approach 1:
The battery in the pony module performs preliminary action by storing solar energy during daytime when sunlight is available, so that power is already available for nighttime or cloudy period operation. This advance energy capture and storage enables continuous operation regardless of immediate weather conditions.
4Loss of energy
If pony module is integrated into the solar tracker system, then energy efficiency is improved and external power dependency is reduced, but the device complexity increases
Solution Approach 1:
The pony module serves multiple functions simultaneously: it provides structural support for the solar panels, acts as the mounting base for the drive device and controller, generates electrical power through its solar panel, stores energy in its battery, and supplies power to all tracker components. This multi-functionality justifies the added complexity by delivering comprehensive system benefits.

AI summary
A pony module having a solar panel may power a controller and/or drive device in a solar tracker. The pony module may be mounted directly on the drive device or a cradle supporting a solar panel support (e.g., a torque tube) attached to the drive device. The controller may be mounted on the solar panel of the pony module or may be mounted on the torque tube itself.
