Energy Calculators

Estimate electric heating savings from insulation, plus electricity costs, solar, EV charging and backup runtime scenarios.

Available energy calculators

6 calculators for this project type.

Energy & UtilitiesElectricity Cost CalculatorCalculate energy consumption and cost for appliances or equipment over a chosen period.

Energy & UtilitiesSolar Installation Cost CalculatorSize a panel-count scenario, calculate DC kilowatts and model energy production separately from the installed project budget.

Energy & UtilitiesHome Battery Cost CalculatorCompare nominal battery energy, depth of discharge and assumed inverter losses before pricing equipment and installation.

Energy & UtilitiesHeating vs Cooling Operating Cost CalculatorPrice two distinct delivered thermal loads with their appropriate seasonal electrical efficiency assumptions.

Energy & UtilitiesSolar Panel Payback CalculatorCompare a user-specified solar investment with annual energy value and model the year when cumulative savings recover its cost.

Energy & UtilitiesInsulation Upgrade Savings CalculatorCompare seasonal conductive heat losses before and after an insulation upgrade using your local weather assumptions.

Planning energy projects

Electricity Cost and EV Charging Cost compute purchased kilowatt-hours. Solar Payback compares annual bill offsets with project cost, while Home Battery and Generator Runtime estimate backup duration with very different storage and fuel assumptions. Neither model predicts actual bills without representative operating inputs.
