Solar & Renewable Calculators

Solar Panel Output is evaluated from Panel Wattage, Number of Panels and Peak Sun Hours per Day. The calculation reports System Size, Daily Output and Annual Output.

Solar System Size is evaluated from Monthly Electricity Usage, Peak Sun Hours per Day and Panel Wattage. The calculation reports Recommended System Size, Number of Panels Needed and Approximate Roof Area Required.

Solar Hours is evaluated from US Region / City and Solar System Size. The calculation reports Peak Sun Hours per Day, Daily Solar Production and Annual Solar Production.

Solar Payback Period is evaluated from System Cost, Annual Electricity Savings and Federal Tax Credit. The calculation reports Net System Cost, Simple Payback Period and 25-Year Net Savings.

Wind Turbine Power is evaluated from Rotor Diameter, Average Annual Wind Speed and Capacity Factor. The calculation reports Swept Area, Estimated Rated Power and Annual Energy Output.

Battery Storage is evaluated from Daily Home Electricity Use, Target Backup Duration and What to Power During Backup. The calculation reports Battery Capacity Needed, Tesla Powerwall 3 Units and Estimated Battery System Cost.

Solar Battery Bank Size is evaluated from Daily Energy Consumption, Days of Battery Backup and Depth of Discharge. The calculation reports Total kWh Needed, Required Usable Capacity and Required Gross Battery Capacity.
