Hey Product Hunt! 👋 I'm an Engineer by profession, and I built CalcFlow to solve a problem I had when researching solar for my home. **The Problem:** Most solar calculators online use generic national averages. But location matters HUGE - Arizona gets 6.5 sun hours/day while New York gets 4.0. Same system, completely different ROI. **The Solution:** I built a calculator with real sun hours data for all 50 states (mapped to ~850 zip code prefixes). Enter your zip + electric bill, get accurate projections for YOUR location. **What it calculates:** - System size recommendation - Total cost after 30% federal tax credit - Payback period - 25-year savings (with inflation & degradation factored in) - Environmental impact Takes 30 seconds, completely free. **Feedback welcome!** Especially curious: - Does the payback period look accurate for your area? - What other features would be useful? - Any confusing parts? Try it and let me know what you think! 🌞
