kW (kilowatt) measures power or the rate of energy use, while kWh (kilowatt-hour) measures energy consumption over time, quantifying the total energy used. kW, or kilowatt, is a unit of power in the International System of Units (SI) that represents a rate of 1,000 watts of energy being used or produced at any instant.
If you’re shopping around for solar panels or battery storage for your home, you’re undoubtedly come across the terms ‘kilowatt’ (abbreviated as kW) and kilowatt-hour (kWh). These terms might be a bit confusing at first, so we’ve written this article to explain these terms and make them easy to understand.
For example, solar panels are often rated in kW to indicate their power generation capacity at peak sunlight, while batteries are described in terms of kWh to specify how much energy they can store and supply over time. A unit of power equal to 1,000 watts.
For instance, a device with a high kW rating might seem powerful but could be more costly to operate if used frequently, as reflected in kWh. Energy providers charge customers based on kWh, not kW, because kWh accounts for the actual energy used over time, making it a more accurate measure of consumption and cost.
