About EV Solar Calculator
Engineering-grade tools for smarter energy decisions
Our Mission
To provide transparent, accurate, and easy-to-use calculators that help people understand the true costs and savings of electric vehicles and solar energy—without the sales pitch.
Why We Built This
The transition to electric vehicles and renewable energy is one of the most important shifts of our time. But making the switch can feel overwhelming:
- Confusing marketing claims — "Save thousands!" but based on what assumptions?
- Hidden costs — Charging equipment, installation, electricity rate increases
- Regional variations — What works in California may not work in the UK
- No single source of truth — Information is scattered across dozens of sites
We created EV Solar Calculator to cut through the noise with honest, engineering-grade calculations that show you the real numbers—not fantasy projections.
What Makes Us Different
Transparent Math
Every calculation shows its formula. No black boxes. If you're an engineer (or just curious), you can verify our work.
Conservative Estimates
We err on the side of caution. We'd rather under-promise and over-deliver than inflate your expectations.
Regional Awareness
Electricity rates, gas prices, sun hours, and incentives vary wildly by location. Our calculators adapt to your region.
No Sales Agenda
We don't sell EVs or solar panels. We don't get commissions. Our only goal is to help you make an informed decision.
