The Toolkit
Built for homeowners and renters nationwide. Real utility rates. Real incentive programs. Real savings.
The biggest barrier to electrification isn't the technology. It's the information gap. We're building free calculators that close it, starting with solar. Real data, real math, available nationwide.
No roof access? No problem. Estimate the energy savings and payback period for plug-in solar panels on your balcony, patio, or window. Factors in your local electricity rate, sun hours, and panel orientation.
Stack every available incentive program: utility rebates, state tax credits, federal programs, and local incentives. See your actual net cost for a heat pump or heat pump water heater after everything is applied.
Enter your appliances and their install years. See which ones are closest to failure and get a prioritized timeline for switching to electric — so you plan the upgrade instead of panicking through an emergency replacement.
Compare monthly and 10-year operating costs using your actual utility rates. See the breakeven point and how rate changes affect the math over time.
Should you switch to a time-of-use rate after electrifying? Input your usage patterns and see which plan saves more, especially with a heat pump and EV.
See how much of your heat pump's electricity your solar panels would offset. Uses local solar production data and your estimated heat pump consumption.
Can your panel handle a heat pump, HPWH, and EV charger? Upload a photo of your panel and see open slots, possible constraints, and cheaper options to ask an electrician about before approving a full panel upgrade.
Compare the operating cost of a heat pump water heater vs. your current gas or electric tank. Factor in your local rates, household size, and usage patterns.
Find the right home EV charger for your vehicle, electrical panel, and budget. Compare Level 1 vs. Level 2, see install cost estimates, and check which chargers qualify for rebates in your area.
Ditch the gas-powered yard tools. Compare electric mowers, leaf blowers, chainsaws, and trimmers by battery life, power, and cost. See which models match your yard size and workload.
Compare heat pump brands and models side by side. Filter by climate zone, home size, SEER2/HSPF2 ratings, noise level, and price. See which manufacturers have the best warranty and installer networks near you.
