How Long Can Solar Battery Power a House During an Outage?

Water heating accounts for an average of 18% of the total energy used in the household, or around 162 kWh per month. On a normal day, a water heater runs for around 2 to 3 hours a day, which means that it will consume roughly 4-5 kWh of electricity a day.Heat pump water heaters are more efficient and can run on around 2.5 kWh per day.
