Watts are units of power measured over one second. If one watt of electric power is used for one hour, the total volume of power consumed is expressed as one watt hour, or 1Wh. Similarly, 1,000 watts of power is expressed as one kilowatt (1kW) and 1,000 watt hours as one kilowatt hour (1kWh). If a 2kW system produces power continuously for five hours, the total volume of power generated is expressed as 10kWh.
