One kilowatt equals 1,000 watts. A kilowatt-hour (kWh) is a way to measure energy, or the amount of electricity used over time. . When shopping for solar panels for your home, you'll come across the terms kilowatts (kW) and kilowatt-hours (kWh). While these may seem like technical terms that only electricians need to know, they're important to understand if you're planning to go solar. Kilowatts are measurements of energy. . Definition: A kilowatt is a unit of power representing a rate of 1000 watts of electrical energy. Use in Solar Panels: KW denotes a system's power capacity or maximum output in solar systems. But what exactly does this mean?.
