Success Story: Case Study by Techstack
Our experience as a custom software development company in New York includes building specialized systems that improve quality control and operational efficiency in real production environments.
Computer vision for solar panel quality control
We worked with a New York–based solar panel manufacturer to replace manual inspections with an automated computer vision system. The solution delivers sub-millimeter measurement precision, helping detect defects earlier while reducing inspection time and production slowdowns.
By handling varying image resolutions at production speeds, the solution enables the client to increase manufacturing output while maintaining strict quality standards—critical for competing in the solar panel market.
