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! 🌞
