## What is SunEyed?

Know your real solar savings before you talk to anyone.

SunEyed calculates your personalized solar ROI using real weather data from over 40,000 stations worldwide. Enter your electricity bill, configure your roof panels, map obstructions, and get an accurate payback period in minutes — entirely on your device, with no account required.

HONEST ANALYSIS, NO SALES PITCH
SunEyed is built for homeowners who want the facts first. No sign-up. No data harvesting. No pressure. Your numbers stay on your phone. When you're ready, you can share your analysis as a PDF with any installer of your choice — on your terms.

HOW IT WORKS
  1. Enter your electricity usage and rate
  2. Configure your roof panels — set direction, slope, and number of panels for each roof face
  3. Map obstructions — trace trees, chimneys, and neighboring buildings directly on the sun path chart
  4. SunEyed calculates your annual production, yearly savings, and break-even period using real local weather data

KEY FEATURES
  • Solar savings and break-even calculation based on real weather data
  • 40,000+ weather station database — accurate for locations worldwide
  • Multi-array support — configure multiple roof faces independently
  • Camera and motion sensor obstruction mapping — physically point your phone at obstructions and trace them onto the sun path chart
  • Monthly usage vs. production comparison with net metering support
  • Adjustable panel specs — wattage, efficiency, system losses, array type
  • Export a PDF summary to share with installers as a request for quote
  • Works entirely offline — all calculations run on device
  • No account, no sign-up, no subscription

PRECISE WHERE IT MATTERS
Most solar calculators use regional averages. SunEyed matches your exact coordinates to the nearest weather station in its database, giving you monthly solar radiation values specific to your location. The obstruction tool goes further — it models how trees, chimneys, and other structures cast shadows across your roof throughout the year, reducing your estimated production only where the sun is actually blocked.                                                                                                              

YOUR DATA STAYS ON YOUR DEVICE
SunEyed does not require an account. Your electricity usage, location, and roof configuration are stored locally on your phone and never uploaded to any server.                                                                                                         

FREE FOR PERSONAL USE
  • SunEyed is completely free for homeowners evaluating solar for their own home. No subscription, no hidden fees, no expiration.
  • Using SunEyed in a professional or commercial context — as a solar installer, energy auditor, or contractor — requires a commercial license. Visit suneyed.com for details on professional use and upcoming installer features.
