Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing solar panel systems lack secure metering solutions, making them vulnerable to falsification of energy output data and theft, particularly when used for grid contributions or carbon credit assessments.
Innovation Solution
Embedding trusted hardware, such as tamper-resistant smart card cores, directly into solar power conversion devices to enhance the integrity of metering data and prevent unauthorized tampering, with a security module generating trusted digital certificates for secure data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If solar panels are used in unsecured locations for grid contribution or carbon credit assessment, then energy generation capability is improved, but vulnerability to falsification of metering data and theft increases
Solution Approach 1:
The patent embeds security modules and trusted hardware directly into the solar panel manufacturing process before deployment. This preliminary integration of security features (digital certificates, tamper-resistant hardware, secure metering circuits) ensures that the panels are inherently protected against falsification and theft from the outset, enabling their use in unsecured locations for grid contribution and carbon credit assessment without compromising data integrity.
2Measurement precision
If separate metering components are used to measure electrical output, then measurement function is added, but ease of tampering with metering data increases
Solution Approach 1:
The patent merges the security module, metering circuit, and solar panel into a single integrated unit. The security module is embedded within the panel structure, and the metering circuit is physically connected to the solar cell output before any external components. This integration eliminates separate tamperable interfaces and creates a unified system where metering data cannot be accessed or modified without detecting the tampering attempt.
3Reliability
If trusted hardware is embedded into solar power conversion devices, then integrity of metering data is improved, but device complexity increases
Solution Approach 1:
The patent designs the embedded security module to perform multiple functions: it serves as both a cryptographic authentication device (storing digital certificates and private keys) and a physical tamper-detection mechanism. The same embedded hardware also functions as the metering circuit interface, combining security, measurement, and communication capabilities into a single multi-functional component that reduces overall system complexity despite adding security features.

AI summary
A solar power conversion device has an embedded security module for creating trusted metering data in relation to power generated and for delivering it to a metering data output. The security module might for example be constructed as an integrated circuit card constructed using semiconductor chip fabrication and assembly techniques to be integral with the solar power conversion device. The device might comprise more than one solar cell mounted on a panel to form an array. There may further be provided a panel management module for collating data, for instance from multiple cells, prior to transmission over a network via the metering output. The panel management module might comprise for example a subscriber identity module and the metering data output may provide associated mobile telephone endpoint technology so that the metering data can be transmitted over an air interface.
