About EnergyTools
Free, data-driven solar energy tools built for homeowners who want to make informed decisions.
Our Mission
EnergyTools exists to give every homeowner free access to the same quality of solar analysis that installers use internally. We believe transparency empowers better decisions — whether you're comparing quotes, sizing a system, or evaluating your payback period.
Our calculators use real NREL data, localized utility rates, and current incentive programs to deliver estimates you can trust. No sales pressure, no lead-bait — just honest numbers.
What We Offer
ROI Calculators
Estimate your solar return on investment, payback period, and lifetime savings.
Location-Based Data
Get localized cost estimates, sun-hour data, and incentive lookups for your area.
Quote Comparison
Compare installer quotes side-by-side with red-flag detection and scoring.
Tax Credit Guidance
Navigate federal and state incentives, including deadline tracking and eligibility checks.
Why Free?
We believe homeowners deserve access to accurate solar data without paying for it or signing up for sales calls. Our tools are funded through optional referral partnerships with certified installers — you're never obligated to use them.
Every calculator runs entirely in your browser. We don't store your data, sell your information, or share your inputs with third parties. Your privacy is built into the architecture.
