What ElectrifyCalc is
ElectrifyCalc is a home electrification hub: interactive tools plus long-form guides for decisions that involve real money and safety — solar payback, lease vs. buy vs. PPA, EV charger install cost, and whether your electrical panel can handle new loads. We focus on the United States (regulatory context, incentives, and typical utility pricing) so the math matches how quotes are actually built.
Why we built it
The residential solar Investment Tax Credit (Section 25D) expired December 31, 2025. Many older tools still assume a federal credit that no longer exists for homeowners, which quietly breaks payback and lease comparisons. At the same time, EV owners often get generic “you might need an electrician” advice without a transparent load methodology.
This site exists to close that gap: 2026-accurate assumptions where the rules are clear, explicit caveats where they are not, and formulas you can trace. Our methodology page documents the NEC, NREL, and EIA pieces behind the calculators.
Trust, expertise, and transparency
Electrification decisions sit next to money and safety — what Google calls YMYL topics. We treat the math like engineering documentation: assumptions are named, limits are stated, and references point to public standards (e.g. NEC articles), government statistics (EIA electricity rates), and national-lab methods (NREL PVWatts-style production factors). Guides separate what follows from statute versus what varies by utility territory or state program, because overstating certainty erodes trust faster than careful hedging.
For line-by-line formulas and citations, start with our methodology page — it is the technical companion to this About page.
How we keep content current
Federal credits and state rebates change with legislation and agency guidance. When deadlines shift — for example the Section 30C window for EV charger hardware — we update calculator defaults and supporting guides so headline numbers do not drift from what you would read on IRS materials. High-stakes articles may show a last-reviewed or updated date in front matter so freshness is visible in search.
If something reads wrong or out of date, email info@electrifycalc.site. Treat it like a bug report: we route corrections into code and copy the same way we fix broken links.
Planning tools, not certifications
ElectrifyCalc sits in Google’s YMYL space — decisions can involve tens of thousands of dollars and electrical safety. Outputs are estimates for planning and education. Always confirm panel work, permits, and tax positions with a licensed electrician or qualified tax professional before you commit.
What we ship
Calculators — solar & financing: Solar ROI (NREL-style production and EIA rates, no Section 25D for homeowner installs), Lease vs Buy vs PPA (long-horizon comparison), and EV charger installation cost (with Section 30C called out through its June 30, 2026 deadline where applicable).
Tools — EV & electrical load: Panel capacity (NEC 220.82 optional method), charging cost and time, panel upgrade ballpark, solar offset for EV miles, and charger amperage comparison — each designed to return a result on the page without a signup wall.
Guides: Cornerstone articles on incentives, sizing, and costs — cross-linked so you can move from theory to a calculator in one click.
How we treat data
- Sources in the open. Constants and formulas tie back to named references — NREL PVWatts-style production factors, EIA average rates, NEC articles for load calcs — so assumptions are inspectable, not hidden.
- No invented numbers. Where a figure is still a placeholder or estimate, we treat it as such in code and copy; we do not present guesses as survey data.
- Tax rules as labeled. Section 25D is treated as expired for residential solar as described in our product rules; Section 48E (third-party / commercial) and Section 30C (EV chargers) are referenced with the dates that apply to them. When law is ambiguous, we say so.
- Tests on the math that matters. Core calculation paths are covered by automated tests so refactors do not silently change payback or load results.
Principles
- Free to use. You see outputs immediately — no account required to run a tool.
- Neutral by design. Results are driven by inputs and cited assumptions, not by partnerships with installers or equipment brands.
- Calm, direct copy. We avoid hype and “save the planet” framing; we focus on whether the numbers work for your situation.
Independence & revenue
ElectrifyCalc is an independent project — not VC-backed, not owned by an installer. Revenue comes from contextual advertising (e.g. Google AdSense) and affiliate links where we recommend products; those programs do not change calculator logic or ranking of your results. Where a page earns commission, we disclose it (see our affiliate disclosure).
Built and operated independently, with a U.S. homeowner audience in mind.
