Solution Overview

Problem

Current monitoring systems for renewable energy power systems, such as solar arrays, fail to accurately differentiate between environmental factors and system issues, leading to inefficient diagnosis and potential loss of generation capacity due to incomplete data and reliance on costly sensors.

Innovation Solution

A computer processor-based method that compares the performance of multiple renewable energy systems within a geographic area using diagnostic variables like weather and system cover status, calculates normalized performance, and alerts consumers to underperformance, thereby identifying system-specific issues without the need for extensive sensor networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional monitoring systems use extensive sensor networks to detect system issues, then measurement precision improves, but device complexity and cost increase

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidsensor network complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates virtual copies of physical sensor data by using weather service data and geographic information to generate expected performance models. Instead of deploying extensive physical sensors, the system copies environmental data from weather services and uses it to create virtual performance baselines for comparison with actual system performance.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent introduces geographic information and weather service data as intermediary elements between the physical environment and the monitoring system. These intermediaries provide environmental context that allows the system to differentiate between weather-related performance variations and actual system issues without requiring direct environmental sensing.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Measurement precision

If monitoring systems collect comprehensive environmental data to differentiate environmental factors from system issues, then diagnostic accuracy improves, but loss of information increases due to incomplete data

Engineering Contradiction:
Improveissue differentiation accuracyVSAvoidenvironmental context data
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent makes the monitoring system universal by integrating multiple data sources including weather services, geographic information, and performance data. This multi-functional approach allows a single system to collect, process, and analyze diverse environmental and operational data to comprehensively differentiate between environmental factors and system issues.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system continuously compares actual performance data against expected performance data derived from environmental conditions, creating a feedback loop. This feedback mechanism allows the system to learn from discrepancies and improve its ability to differentiate between environmental variations and actual system problems over time.

Inventive Principle:
Principle #23Feedback

3Productivity

If monitoring systems perform detailed analysis of all performance factors, then productivity improves through better diagnostics, but loss of time increases due to complex data processing

Engineering Contradiction:
Improvediagnostic efficiencyVSAvoiddata processing time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent applies partial action by focusing diagnostic efforts only on the most significant performance factors and using threshold-based filtering. Instead of analyzing every possible variable in equal detail, the system identifies and prioritizes key performance indicators and environmental factors that have the greatest impact on system performance, processing them with higher detail while using simpler analysis for less critical parameters.

Inventive Principle:
Principle #16Partial or excessive action
