The Client

A Reputed Renewable Energy Company

The client, based in the UK, is a leading manufacturer of solar panels. They specialize in designing, manufacturing, installing, and maintaining solar panels for residential and commercial use.

Project Requirements

Annotating 5000+ Solar Panel Images to Improve the Defect Detection Ability of an AI Model

For solar panel maintenance, the client wanted to utilize an AI system that could assist in:

Defect Detection

Identifying potential issues like micro-cracks, delamination, or hotspot heating in solar panels through image analysis.

Efficiency Optimization

Analyzing shading patterns and other environmental factors to optimize panel placement and maximize energy output.

The client had over 5000 solar panel images (including RGB and thermal spectrums) captured by drones, which they wanted to be annotated accurately to train machine learning models.

Our Solution

A Collaborative Approach to High-Quality AI Training Data

After understanding the project's complexity, we engaged a dedicated team of 10 image annotators. We used the polyline annotation technique to mark defects and anomalies in both the RGB and thermal images.

Comprehensive Training

We provided initial training to ensure our annotators were proficient in using the client's proprietary image annotation tool and familiar with the specific types of defects and issues that needed to be identified.

Defect Identification and Annotation

Based on the client's project specifications, we developed detailed image annotation guidelines. Our team divided the provided image datasets into manageable segments to ensure thorough inspection and precise labeling.

Quality Assurance by Subject Matter Experts

We employed a strategic human-in-the-loop approach: Initially, our annotators manually labeled datasets, which served as a reference for the client's proprietary annotation tool to tag all the images.

Iterative Feedback and Continuous Improvement

We maintained close collaboration with the client through regular feedback sessions, which allowed us to refine our processes and annotation criteria continually. We assigned a project manager to provide regular progress updates to the client.

Project Outcomes

Impressed by our service quality and the tangible improvements in their operations, the client signed a 1-year project contract with us. Key outcomes achieved by the client include:

35% increase in the accuracy of the client's defect detection algorithms

20% reduction in overhead cost as the client was able to proactively address defects and minimize downtime for repairs

Improved AI models facilitated swift identification of solar panel defects, streamlining maintenance processes
