Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photovoltaic power generation systems are inflexible and costly to design and expand, as they are heavily dependent on environmental conditions and geometric constraints, leading to either over- or under-capacity, which can result in inefficient power output and high initial installation costs.
Innovation Solution
The implementation of adaptive photovoltaic systems that include a power hub and adaptive maximum power point tracking (MPPT) translator modules, which allow for variable solar panel string configurations and power output capacities, enabling scalability and modularity to match changing power needs and environmental conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a solar power system is designed with sufficient power generation capacity to fully meet energy needs and provide room to grow, then future power needs can be met, but initial installation costs become prohibitive
Solution Approach 1:
The system employs dynamic reconfiguration of solar panel strings through switching elements that allow panels to be dynamically connected or disconnected from the circuit. This enables the system to adapt its power generation capacity over time, starting with a smaller, more affordable initial installation that can be expanded by adding or activating additional panel strings as needed, rather than requiring full future capacity upfront
Solution Approach 2:
The solar array is divided into multiple independent panel strings that can be individually controlled and reconfigured. Each string can be independently connected to the load or bypassed, allowing the system to operate at different capacity levels. This segmentation enables incremental expansion where users can start with fewer strings and add more later without redesigning the entire system
2Area of stationary object
If solar panel arrays are designed to meet environmental geometric space constraints, then installation feasibility improves, but system flexibility to match power needs is reduced
Solution Approach 1:
The system uses dynamic switching elements that allow the electrical configuration to change independently of the physical panel arrangement. Even when panels are fixed in position due to geometric constraints, the switching elements enable dynamic reconfiguration of which panels are active and how they are connected, providing power output flexibility without requiring physical panel movement
Solution Approach 2:
The array is segmented into multiple independently controllable strings that can be selectively activated. This allows the system to optimize space utilization by fitting panels into available geometric areas while maintaining flexibility through independent control of each string, enabling the system to match power output to实际需求 even with fixed physical layouts
3Quantity of substance
If a small solar system is installed to reduce initial costs, then installation affordability improves, but the system becomes locked and cannot fully meet future energy needs
Solution Approach 1:
The system incorporates dynamic switching elements that enable easy reconfiguration as the system expands. Users can start with a small number of active panel strings to keep initial costs low, and later activate additional strings or reconfigure existing connections as more panels are added, allowing the system to grow with the user's needs without requiring a complete redesign
Solution Approach 2:
The switching elements and control system are designed to handle variable configurations from small to large scale operations. The same basic system architecture and control logic work whether one panel string is active or multiple strings are in use, providing a universal platform that supports incremental expansion from a small affordable starting point to a larger system that meets future energy requirements

AI summary
Apparatuses, systems, methods, and computer program products are disclosed for an adaptive photovoltaic system. Solar panel strings comprise solar panels. An adaptive maximum power point tracking (“MPPT”) translator module is in electrical communication with the solar panels of the solar panel strings. An adaptive MPPT translator module comprises a voltage converting unit. An adaptive MPPT translator module is configured to control the solar panels of the solar panel strings according to a MPPT translator algorithm so that each of the solar panel strings vary in number of the solar panels and in power output capacity of the solar panels and physical configurations of the solar panel strings are adaptive to power needs, physical surfaces, and environmental geometric space constraints. A power bus provides electrical communication between the adaptive MPPT translator module and a power hub in electrical communication with a power demand.
