 # Know the Kilowatt and kWh Energy Usage Per Day

### Many individuals are wondering how do kilowatt and kWh differ?

They may have a general idea but aren’t sure exactly what that means. Both words synonyms for electricity are “kilo watt” and “kilowatt hour.” A more accurate definition of both kilowatt and kWh would be to say; the amount of energy used by an appliance at one time. However, the initials stand for; K, which stand for 1000, and H, which stand for half hour.

How long an appliance uses one unit of kilowatt can vary greatly depending on the use. If someone wants to know how much electricity their appliances use in a month they would look up the estimated usage in kilowatt units (kWh) and divide it by the number of months they own the appliance. Then they would look up their estimated per kilowhour usage. The difference between the two is one thousandth of a kilowatt-minute. It would be very difficult to determine the exact amount of energy used by an appliance during normal usage, but it can be quite easy to see how much energy is consumed when the temperature drops and the clocks spring forward or back.

### Another factor that will affect the results

When comparing the kilowatt and the kwh there are several factors that need to be considered. These factors include the age of the equipment, how often the appliances are used, the cost of operating the machine, and the cost of the electricity itself. Each of these factors will have a different impact on the comparison. An older model of machine will naturally use less electricity than a newer model that has a new design. Another factor that will affect the results of the calculation is how often the machine is used and the cost of operation.

Older model appliances that are used less will use fewer kilowatt per hour than newer versions. This means that the efficiency of the system needs to be compared with the expected number of two that it will be expected to provide. If the actual number used is much more than the expected number of kwh it will result in an increase in the cost per unit of energy. A modern stove will use considerably more kilowatt than a slow-burning fire-place, but this can be made up for by the increased efficiency. This increase is also multiplied by the number of years in which the equipment is expected to last, and therefore the change in cost per kwh over time.

### Assuming that the solar system can provide this amount at any given time

The calculation should also take into account the maximum number of hours in a day that the solar system can provide the desired amount of energy for the home. Assuming that the solar system can provide this amount at any given time the kilowatts used in each day will be calculated. The cost per kilowatt hour is then given as a percentage of the maximum sunlight required. The calculation can then be done on the assumption that the maximum sunlight occurs during the hours of maximum sunlight. If the maximum sunlight occurs at noon, or at any other time other than when the solar system is most efficient, the calculation would be different.

As can be seen, there are significant differences between the values obtained using the kW and kWh methods. It is important that these values are used in an overall comparison to determine the true cost of installing a solar home system. Many companies selling various types of energy saving appliances will provide data sheets that can be used to determine both the kW and kWh rates for a particular product. In many cases the estimated costs for installing a solar home system will be based on assuming a roof height of six feet. Installing a system based upon estimated energy usage per day using a roof height of five feet would almost certainly result in an under estimated cost for the energy savings.
