The average price of electricity continues to rise in Arizona. Many homeowners are looking for ways to reduce their energy consumption and lower their monthly bill. One way to do this is by understanding which household appliances use the most electricity and how much they cost to operate. The following Arizona appliance wattage chart and electricity usage chart provides a quick guide to this information.
This chart can also help you determine which appliances your solar battery can run and for how long. The kilowatt-hour (kWh) is the standard measurement utility companies use to measure electricity supplied to their customers. kilowatt-hours is a measurement of electricity used over time.
If your solar battery has 10 kilowatt-hours (kWh) of storage capacity, that means it can power appliances for 10,000 watt hours. A single 8 watt LED light bulb uses 0.008 kWh (8 watt hours) of electricity per hour. Thus, a 10 kWh battery can run a single LED light bulb for 1,250 hours. To calculate this, take the total amount of storage capacity (10 kWh) and divide it by the usage (0.008 kWh) to arrive at 1,250.
Further, the chart lists the wattage (also known as demand) of all common household appliances. Demand is the amount of energy an appliance draws at a single point in time, and is calculated in kilowatts (kW). 1 kWh equals one hour of electricity usage at 1 kW of demand, and thus a 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is kW x time = kWh.
The chart also details the energy costs for the two main electric utilities in Arizona: Arizona Public Service (APS) and Salt River Project (SRP). In addition, the chart lists how much the appliances will cost when powered by a solar panel system.
