Should You Switch to an Electric Vehicle or Go Solar in 2026?
With electricity prices and gas costs fluctuating, making the switch to an electric vehicle or installing solar panels is one of the biggest financial decisions homeowners face. Our free calculators help you cut through the marketing and see the real numbers.
How Much Does It Cost to Charge an Electric Car?
The average American drives about 13,500 miles per year. For a typical EV that uses around 30 kWh per 100 miles, that works out to roughly 4,050 kWh of electricity annually. At the national average electricity rate, that's significantly less than what you'd spend on gasoline — but the exact savings depend heavily on your state's rates. Our EV Charging Cost Calculator uses your state's actual rates to give you a precise estimate.
Are Solar Panels Worth It? Federal Tax Credits for 2026
The federal Investment Tax Credit (ITC) still covers 30% of solar installation costs in 2026, making this one of the best times to go solar. Combined with state-level incentives — some states offer an additional 10-25% in rebates or credits — the payback period for solar panels has dropped to as low as 5-7 years in sun-rich states. Over 25 years, the average homeowner saves tens of thousands of dollars. Use our Solar Panel ROI Calculator to see your exact savings.
EV vs Gas: The True Cost Comparison
An electric vehicle isn't just cheaper to fuel — maintenance costs are 30-50% lower because there's no oil changes, fewer brake replacements (thanks to regenerative braking), and far fewer moving parts. Our Total Cost of Ownership Calculator factors in purchase price, fuel, maintenance, insurance, and depreciation to give you the complete picture over 5 years.
Why Use Our EV & Solar Calculators?
EVSolarCalc offers free, no-signup calculators built for homeowners and car buyers who want real numbers, not estimates based on national averages. Each calculator uses actual utility rates, gas prices, and solar incentive data for your specific state — giving you a personalized picture of what switching to an EV or going solar actually costs where you live.
Our data is updated regularly with figures from the U.S. Energy Information Administration, AAA gas price reports, and state utility filings. Whether you're comparing an electric vehicle to a gas car, estimating your monthly charging bill, or figuring out when solar panels would pay for themselves, our tools show you the math transparently — no marketing language, no hidden assumptions.
Too many "free calculators" bury results behind email signups or round down to suspiciously convenient numbers. Ours are genuinely free, instant, and built to show you exactly how every figure is calculated. If a switch to an EV or solar doesn't pencil out for your situation, we'll tell you that too.
Frequently Asked Questions
How accurate are these calculators?
Very accurate for planning purposes. We use state-level electricity rates from the U.S. Energy Information Administration and gas prices sourced from AAA. The solar calculator uses NREL sun-hour data and actual state incentive percentages. Results are estimates — your exact savings will vary based on your utility plan, driving habits, and roof orientation — but they're far more precise than national-average tools.
Do I need to create an account to use the calculators?
No. All calculators on EVSolarCalc are completely free with no signup, no email address required, and no paywalled results. Enter your details and see your numbers instantly.
Which states are supported?
All 50 U.S. states. Each state has its own average electricity rate, gas price, solar sun-hours, and incentive data built into every calculator. You can also override the defaults with your actual utility rate for an even more precise estimate.
Is the federal EV tax credit included in the calculations?
The Gas vs EV Cost Calculator and EV Charging Cost Calculator focus on ongoing fuel costs and do not include the one-time $7,500 federal EV tax credit. The EV Total Cost of Ownership Calculator does include the tax credit as an adjustable field, since eligibility varies by vehicle and income.
Does going solar make sense if I also drive an EV?
For most homeowners, yes — combining rooftop solar with an EV is one of the highest ROI home improvements available in 2026. Solar panels can effectively eliminate your EV charging costs, and the federal 30% Investment Tax Credit applies to the full system including EV charger installation. Use our Solar Panel ROI Calculator to see your specific payback period.
