Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing renewable energy systems, such as photovoltaic solar panels and wind turbines, are vulnerable to damage from extreme weather conditions, leading to reduced reliability and reluctance to install them in areas prone to hurricanes, tornados, and severe storms.
Innovation Solution
The use of storm-resistant containment units with movable doors or panels that can be closed during adverse weather to protect the renewable energy systems and reopened for energy collection when conditions improve, utilizing mechanisms like tambour doors or pivoting panels, and tilting masts for wind turbines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If PV solar panels are permanently attached onto mounting poles and frameworks suspended above surrounding structures, then energy collection is enabled, but the panels are exposed to damaging effects of extreme weather conditions such as wind, hail and airborne debris
Solution Approach 1:
The system divides the solar panel installation into separate functional components: a fixed mounting structure and a movable protective cover. The cover can be independently positioned to either expose or protect the panels, allowing energy collection and weather protection to occur at different times without compromising either function.
Solution Approach 2:
The protective cover is designed to be movable rather than fixed, transitioning between open and closed positions. This dynamic element allows the system to adapt its state based on weather conditions, enabling panels to be exposed during favorable conditions for energy collection and protected during adverse conditions.
2Object-affected harmful factors
If containment units with moveable protective doors are used to shield PV solar panels from extreme weather, then protection from damage is provided, but the system complexity increases
Solution Approach 1:
The protective cover utilizes a flexible or semi-rigid shell structure that can be moved into position to protect the panels. This approach provides effective weather protection while using relatively simple structural elements compared to fully rigid enclosed systems, helping to manage overall system complexity.
Solution Approach 2:
The system incorporates automated controls that can detect weather conditions and automatically position the protective cover without requiring complex manual intervention systems. This self-service capability reduces operational complexity while maintaining effective protection.
3Object-affected harmful factors
If moveable protective doors are closed during extreme weather, then protection is provided, but sunlight cannot reach the PV solar panels for energy collection
Solution Approach 1:
The protective cover is designed to dynamically transition between closed and open states based on external conditions. During extreme weather, the cover remains closed to provide protection. During favorable weather conditions, the cover opens to allow sunlight to reach the panels for energy collection, thus resolving the contradiction between protection and energy generation.
Solution Approach 2:
The system operates in periodic cycles, alternating between protection mode (cover closed) during adverse weather and energy collection mode (cover open) during favorable weather. This periodic switching allows the system to fulfill both protective and generative functions over time.

Function Achieved in This Case
Provides protection from extreme weather, allowing renewable energy systems to operate reliably and resume energy production quickly when conditions are favorable, enabling the formation of hardened micro-grids for critical infrastructure support.
Implementation Method 1
photovoltaic solar panels, because these local power sources, e.g. 'Micro-Grids', are generally considered to be nearly 'uninterruptable'

AI summary
A Surface-affixed, Storm-Resistant Containment Unit involves a shelter structure, with internally-mounted photovoltaic solar panels, and movable doors which may be ‘closed’ to protect the photovoltaic solar panels from storm-related damage, e.g. hail, extreme wind and airborne debris. When weather conditions improve, the movable doors may be ‘opened’, allowing sunlight to strike the undamaged photovoltaic solar panels, and renewable energy production to resume. These Storm-Resistant Containment Units may be installed, and electrically connected in multiples to comprise a storm-resistant, commercially-sized, renewable power generating station (or ‘Micro-Grid’) for use in geographic areas prone to severe storms and hurricanes. Such storm-resistant, commercially-sized, power generation station may be advantageously applied at existing ‘Brown-Field’ industrial sites that have existing, unused electrical-grid infrastructure.
