The Opportunity

Problem

Students developing solar power prototypes can't reliably simulate designs because current software crashes on basic laptops and lacks mobile support.

Solution

SunProtoHub lets student teams co-build, simulate, and iterate solar prototypes in real-time without software crashes. Share editable links, run group sims on any device including mobiles, and track changes for competitions. Centralized hub prevents version chaos in group projects.

Target Audience

Engineering and renewable energy students building solar power prototypes for coursework or competitions

Differentiator

Real-time multiplayer editing + shared sim engine, tailored for student teams with competition templates
