Off-Grid Solar System Sizing Calculator

Fill Out Load Calculator

Use our Off-Grid sizing tool below to estimate system size. Check out our video on off-grid sizing for details and more information on the design process.

Fill out the table below to estimate energy usage. We’ve included some common household appliances found in off-grid homes. Try to account for everything, keeping in mind that off-grid homes should use efficient appliances, and the major heating loads (water & air heating) are usually not electric.
