Democratizing solar
estimation for everyone.
GeoArce was built to eliminate barriers in solar energy estimation. Whether you're a homeowner exploring options, an installer scoping projects, or a developer evaluating sites — professional-grade analysis should be free, instant, and accessible.
Our Mission
To provide the most accurate, accessible, and comprehensive solar roof estimation tool on the internet — completely free of charge. We believe that the transition to renewable energy begins with information, and that information should be available to everyone regardless of location or budget.
Our Vision
A world where every homeowner can understand their solar potential in under 60 seconds. Where installers can scope projects remotely before site visits. Where the decision to go solar is backed by precise, trustworthy data — not sales pitches.
What drives us
Every design decision and feature is guided by these core principles.
Worldwide Accessibility
Solar energy potential shouldn't be locked behind expensive software or regional restrictions. GeoArce works everywhere, for everyone.
