Watt and kWh are both commonly used units in electrical formulas. To achieve watt to kWh conversion, you need to first have an understanding of these two units, which will help to give you a better understanding of the formulas used in watt to kWh conversion, and the following is an explanation of these two concepts.
1. What is a watt? What is the relationship between watts and kilowatts?
Watt is the unit of power in the International System of Units, and power refers to the rate at which work is done. As an example, assuming that your solar panel has a power of 200watt, then it indicates that your solar panel can produce 200 joules of electricity per second under the ideal conditions for this 200watt solar panel.
Furthermore, watts and kilowatts are not units of the same magnitude, but they are both units that express power, and it is not difficult to make the conversion from watts to kilowatts, you just need to substitute the formula.
Kilowatt (kW) = Watt (W)/1000.
For example, suppose the output power of your solar panel is 200watt, then by substituting the above formula, you can know the output power of your solar panel is 0.2kW.
2. What is kWh?
Kilowatt hour is a unit of energy, usually used to indicate how much electricity is consumed or generated at a certain power for a certain period of time. This unit of energy can be used in many scenarios, such as power companies, equipment energy consumption and power plants, as a simple example, your home electricity bill will be labelled with how many kilowatt-hours of electricity you use this month. 1kWh means that a piece of equipment with a power of 1,000watt continues to work for one hour.
3. What is the role of device operating hours in the conversion from watts to kilowatt-hours and how do I get them?
To realize the conversion from watts to kilowatt-hours, you need one more key data, namely the operating time of the device, which is the intermediate value to realize the conversion from watts to kilowatt-hours, and serves as an aid in the calculation.
For example, if you want to get the running time of solar panels, you need to combine the peak sunshine hours in a day, of course, to get the peak sunshine hours in a day is more difficult, you can calculate the total peak sunshine hours in a year, combined with the formula: the total peak sunshine hours in a year / 365, you can get the average peak sunshine hours per day.
4. Watt to kWh Calculator
After getting the above two key data, you can realize the conversion of watts to kWh. According to the formula:
Kilowatt hour (kWh) = Watts (W)/1000 x the operating hours of the device
For example, assuming that your 200watt solar panel averages 5 hours of peak sunlight per day, and substituting the above formula, you can get that your 200watt solar panel outputs roughly 1kWh of electricity per day.
Of course, you can also utilize a variation of the formula in Watts to kWh, i.e.
Equipment operating hours = kilowatt hours (kWh) / (watts (W) / 1000)
Watts (W) = kilowatt-hours (kWh) / equipment operating hours x 1000
For example, suppose you need your solar panels to output 1kWh of electricity for your use every day, if you are located in an area where the average daily peak sunshine duration is 5 hours, then you want to know how many watts of solar panels you need, you can substitute the data into the formula: watts (W) = kilowatt hours (kWh) / equipment operating hours × 1000, substitute the data into the total number of watts of solar panels you need to 200 The total wattage of solar panels you need is 200W.
5. Summary
In your daily life, you will inevitably carry out the calculation of Watt to kWh, through the in-depth understanding of the Watt to kWh formula, you can easily complete this calculation process, of course, if you do not want to spend too much time in the calculation process above, then the Watt to kWh calculator can quickly and accurately for you to figure out the final result, I believe that this calculator will become a big help in your life.
