Solution Overview
Problem
Existing renewable energy systems for off-grid applications are often expensive, require extensive installation, and lack reliability, especially in emergency situations, as they typically rely on carbon-based energy sources or are limited to single energy sources like wind or solar, and cannot be quickly deployed.
Innovation Solution
A stand-alone integrated renewable electric power station using a modular, intermodal container-based system combining vertical axis wind turbines and solar panels, with a self-deployable and self-protecting design that optimizes energy harvesting through adjustable ducts and obstruction means, allowing for efficient transportation and rapid setup, and includes a controller for optimal wind energy capture and a PV system for solar energy generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a container-based modular system is used, then transportation efficiency and deployment speed are improved, but the system complexity increases
Solution Approach 1:
The system is divided into modular components (wind energy system, PV system, storage system, control system) that can be independently manufactured, tested, and assembled within standardized containers. This segmentation enables parallel development and rapid deployment while maintaining manageable complexity through standardized interfaces.
Solution Approach 2:
The container-based platform serves multiple functions: structural housing, energy generation, energy storage, and control. The standardized container design can accommodate different configurations of energy components depending on application requirements, providing universal applicability across various off-grid scenarios while simplifying logistics and deployment.
2Reliability
If multiple energy sources (wind and solar) are integrated, then energy supply reliability is improved, but the device complexity increases
Solution Approach 1:
The wind energy system and PV system are merged into a single integrated platform with shared infrastructure (container housing, control systems, storage integration). This combining approach achieves diversified energy supply for improved reliability while avoiding the complexity of completely separate systems through unified management and coordinated operation.
Solution Approach 2:
The control system continuously monitors the output and status of both wind and PV systems, automatically adjusting operation to optimize energy generation and storage. This feedback mechanism coordinates the multiple energy sources, managing their interaction to maintain system reliability while keeping operational complexity manageable through automated control.
3Productivity
If adjustable ducts and obstruction means are added to optimize wind capture, then wind energy harvesting efficiency is improved, but the device complexity increases
Solution Approach 1:
The ducts and obstruction means are designed to be adjustable rather than fixed, allowing optimization of wind capture based on varying wind conditions and directional changes. This dynamic adjustment capability improves wind energy harvesting efficiency while maintaining manageable complexity through mechanical adjustment mechanisms integrated into the container structure.

AI summary
The present invention is in the field of renewable energy and in particular a remote energy system (ReWES). Renewable energy typically relates to energy that comes from resources such as sunlight, wind, rain, tides, waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation, hot water/space heating, motor fuels, and rural (off-grid) energy services.
