We know that watts (W) measure the rate of energy usage, be it production or consumption. What Is the Definition of a Kilowatt Hour? When you look at your electricity bill, your consumption is in kWh. If you boiled water in it continuously for an hour, it would use 1,500 watts of power, or 1.5 kWh. The specifications list it as a 1,500-watt appliance. Let’s look at an example using a cordless electric kettle. Similarly, a watt-hour is one watt (W) of power consumed or transferred over an hour. A kilowatt-hour (kWh) is one kilowatt of power consumed or transferred in one hour. Using the solar cells in solar panels as an example, their peak capacity - the maximum power a cell can produce - comes in bright, sunny conditions. ![]() The kilowatt peak (kWp) is the maximum capacity a system can deliver when operating under standard conditions. KWp stands for the kilowatt peak for a system, sometimes known as kil-watt peak or watt-peak. Look at your electric bill and you’ll see that it’s priced in kilowatt-hours (kWh). The 100-watt light bulb requires more electrical energy to illuminate, hence its higher wattage. Think of a 100-watt light bulb - it shines brighter than a 60-watt bulb because it uses electrical power at a higher rate. To put it simply, the higher the wattage, the greater the energy use. Power is defined as the rate at which energy is consumed or produced. īoth watts and kilowatts are methods to measure power or an amount of energy they allow us to quantify the rate at which power is consumed or produced over a period of time. The watt (W) - the rate at which work is being done - was named after Scottish inventor James Watt. The “kilo” part of the word “kilowatt” means a thousand, so a kilowatt is 1,000 watts.Ī watt (W) is a unit of power, measuring power rates over a period of time. What Is a Kilowatt?Ī kilowatt is 1,000 watts of electrical power. By putting less carbon dioxide into the atmosphere, you’ll be helping in the fight against climate change. You’ll also discover how understanding kilowatts can help you save energy, thereby reducing your greenhouse gas emissions. This in-depth guide will cover many of the things you didn’t know about kilowatts, including what they are exactly, how we measure and use them, and a lot more. ![]() While you might be familiar with these terms, there’s a good chance you’ve only scratched the surface. Now the system size (kW) never changes, it is always a 10 kW system on this particular roof, but as solar radiation varies from year to year and the equipment ages, the production or kWh will vary each year due to many variables.Electricity bills and energy suppliers often speak abou t kilowatts and prices per kilowatt-hour. ![]() If it is built facing directly south at an optimum angle to the sun in Colorado I can calculate that in one year that system will produce 14,333 kWh of electricity. So now if you buy a 10 kW sized solar system (about 25 solar PV panels) it is also called a 10,000 watt system or also called a 10 kW system (just move the decimal point left 3 spaces when adding the kilo).x 10) or converted to kilo (meaning 1000) it used 1 kWh. Now if that same light is on for 10 hours the bulb will use 1000 watt/ hrs.If a household light bulb is rated at 100 watts, which describes the power it draws instantaneously when turned on, and you leave that 100- watt bulb on for one hour it will have consumed 100 watts continuously for an hour or as it is called, 100 watt/hr.To help make more sense of this, let me use the light bulb as an example: KWh is what a specific sized photovoltaic system will produce over a given amount of time. Both concepts are referenced when talking about a photovoltaic solar system and important to understand before buying a solar PV system.Ī kW measure power, it represents the actual electrical size of an electrical component, and a kWh measures production of an electrical component such as a photovoltaic system or consumption of a component such as a light bulbs when on. The difference between a kilowatt (kW) and kilowatt-hour (kWh) is the most misunderstood topic while trying to understanding electricity and how we measure power and consumption/production. ![]()
