Annual Energy Consumption (kWh)*
Review your electricity bills to determine the total yearly energy consumption in Kilowatt-hour (kWh) energy units and enter that number here. The calculator will size a Solar PV system to offset the specified amount of energy on a yearly basis.
Desired Annual Energy Off-set with Solar PV*
Being 100% Net-Zero means that you are producing as much energy as you consume in one year; this relies on sizing a system to produce excess energy during the peak producing Summer months, resulting in energy credits that can be used in the Fall and Winter; however, depending on your how many solar panels can be installed on the roof, or your local net-metering agreement details, it may be necessary to off-set a smaller portion of your energy consumption. The Direct-load-displacement method (typically off-setting 25-33% of annual consumption) uses a smaller Solar PV system to avoid exporting power out to the grid, and solely focuses on directly powering the day-time electrical loads with Solar PV power instead.
