What does GridTally do?
GridTally helps homeowners explore home energy upgrades using free calculators in their browser. Users can adjust assumptions to estimate solar panel and battery capacity, compare heat-pump and gas-furnace running costs, calculate EV home charging costs, and explore mini-split BTU and generator load requirements. Worked examples explain the assumptions behind common scenarios. The tools provide preliminary planning estimates to help users prepare questions for installers; they do not replace professional load calculations or engineering designs.
