![]() this unit is so important in measuring the electricity consumption particularly. energy of any device means the power consumed in a given time, this gives the idea how fast or how slow the power is consumed by the electrical appliances. Kilowatt hour is the unit of energy consumed by any electrical appliances. The difference between watts (W) and kilowatt (kw) is that the SI unit of power is watt or W and sometimes the value exceeds 1000W so it is written in terms of kilowatt that is kW, same power considered for 1 hour will be equal to kWh which is the energy consumed by an electrical appliances. it is usually calculated by the product of the voltage and current that is Power (W) = Voltage (V)*Current (I)or alternatively it is also the product of the square of the current and equivalent resistance (R) across the terminals that is Power (W) = Current (I)*Current (I)*Resistance (R). Watt is a unit of power consumed by any electrical appliances. Alternatively in 1Watts there are 0.001 kW. So a question arises that how many watts in a kilowatt the answer is simple, there is 1000 Watts in a 1 kilowatt. Once the Energy is known this can be converted to Units and once the Unit is known, we can calculate the monthly electricity bill. With one kWh of energy, you could power that iron for one hour.Here is a simple online Watts to kWh calculator that converts power to energy. To bring that number to life for you, let’s assume you have an iron that uses 1,000 W of energy per hour. You now know that your setup gives you one kilowatt-hour of energy. Fortunately, for this equation, you don’t need to know any external factors about your system, so you don’t need to worry about converting watts to volts. This means it’ll be producing its full potential when it comes to wattage. We’ll assume your panel gets 4 hours of bright sunlight for this equation. If you have more than one panel, you can simply add the wattage of all the panels together, and use that when doing your calculation. ![]() To make this example simple, we’ll assume that’s the entire capability of your solar panel setup. Knowing these values will help you when you start working on your solar generator watt calculator. ![]() If you’re unsure, feel free to contact us we’re always happy to help make solar simple. You can find this in the user’s manual of your panel, as well as its packaging. To use that formula, you’ll need to know the wattage capability of your solar panels. The watts to kilowatt-hours formula is as follows: Watts, as you know, are represented using the letter W. In mathematical formulas, kilowatt-hours are represented using the letters kWh. Now that you understand the difference between watts and kilowatt-hours, let’s get into the formula you’ll need to use. Have a look at our electric bill calculator for more information on that calculation. If you leave that lightbulb on for 10 hours, you will have used one kilowatt-hour of energy.Ĭalculating this can help you understand your electric bill. Say you have a lightbulb that uses 100 W of power per hour. Here’s an example that illustrates kilowatt-hours: It’s important to remember that it’s a unit used to measure power usage, not time. This would be full exposure to sunlight at the brightest time of day.Ī kilowatt-hour, on the other hand, refers to 1,000 watts being used in an hour. If your panel says it produces 250 W, that means it’s capable of producing 250 units of power when it’s in optimal conditions. So how do watts fit into the solar panel picture? Well, since watts measure power, they will give you a quantification of the power produced by your solar panel. If you’re looking for a watt calculator, we have a guide on how to do that as well. The symbol for watt is W, which you’ll see us using in the formula below. The watt is the unit used to measure power, hence the definition “the rate at which energy is consumed.” We have a useful guide on converting watts to amps if that’s what you’re looking for.Įnergy is defined as the capacity to do work, while power is defined as the rate at which work is done. This shouldn’t be confused with amps, which are used to measure current. It’s the amount of energy an item needs to perform its job, and describes the rate at which energy is consumed. But first, we want to ensure you have an understanding of both units, which are used to measure power.Ī Watt is a single unit of power. Converting watts to kilowatt-hours is as simple as using a formula.
