Are you still spending 4 hours on completion photo logs?
After finishing a low-voltage NONFIT solar power plant construction site, do you open Excel in the office at night, paste photos, and type names—does this work take more than 4 hours per project?
During busy periods with consecutive construction sites, you might find yourself creating logs late into the night, draining your physical and mental energy. This is not "craftsman's work"; it's an "administrative burden."
Godo Kaisha 440 is releasing "AI Daicho-kun," a web service that completely solves this problem, in May 2026.
It is the industry's first AI automation tool specializing in completion photo log operations for low-voltage NONFIT solar power plants.
Before - Previously, 4 hours for shooting, organizing, and writing... After - Just take pictures and let AI handle it.
"Just take pictures" and the log is complete—What is AI Daicho-kun?
AI Daicho-kun is a web service that automatically generates completion photo logs simply by taking pictures with a smartphone. AI automatically identifies and sorts components unique to solar power plants, such as panels, PCS, junction boxes, racks, and fences, and outputs them as a report.
■ Main Features
■ AI automatic sorting: AI automatically classifies photographed images by component. No manual organization required.
■ Automatic input to electronic blackboard: Automatically inputs descriptive text for photographed images.
■ Automatic report typesetting: Automatically generates general-purpose photo logs.
■ Missed shot detection: AI checks a list of required shots and provides real-time warnings on site. Prevents discovering "missing" shots later.

Introduction Effect: Photo log work per project reduced from "4 hours to approximately 20 minutes"
By introducing AI Daicho-kun, the completion photo log work time per project can be reduced by up to 80%.
*Calculated at an hourly wage of 2,750 yen. Actual reduction effects vary depending on project scale.

Why "Specialized in Low-Voltage NONFIT"?—Development Background
Many construction management web services on the market are designed for general construction and civil engineering. As of now, there are virtually no services specifically for low-voltage NONFIT solar completion log operations.
The representative, Yamamoto, personally experienced this "inefficiency of log work" while managing his own renewable energy EPC business.
"Small and medium-sized EPC companies and sole proprietors are sticking photos in Excel and printing A4 late at night. This time is not spent on improving construction quality or acquiring new projects."—From this conviction, he decided to develop the service in-house.
