How Do I Find the Annual Electricity Usage (total kWh per year)?

After estimating your roof size, you will want to determine your annual electricity usage.

Take a look at your most recent electricity bill. In addition to individual charges, you should see the average killowatt hours (kWh) per month, as well as the total annual kWh usage. According to the U.S. Energy Information Administration, the average annual electricity consumption for a U.S. residential utility customer was 11,280 kWh, which is an average of 940 kWh per month.

This calculation helps us understand your current price of electricity, and TerraSol Energies will help you dramatically reduce electricity costs when you choose to make the switch to solar power.
