kW or kilowatts are power and not interchangeable with speed
The number of kilowatts used by a device in one hour. This gives you the rate at which energy is consumed.
No device uses "kilowatts per hour". A watt or kilowatt is a unit of power, not of energy. That means that the "per hour" or "per second" is already implied - the watt refers to a "rate of energy conversion" - not to an amount of energy. If a devices uses a certain amount of kilowatts, it uses this amount all the time while it is on - whether it is kept on for a second or for several days.
To calculate the energy generated by a solar panel in one hour in kilojoules, you would need to know the power output of the solar panel in kilowatts. You can then convert kilowatts to kilojoules by multiplying by 3,600 (since 1 kilowatt-hour is equal to 3,600 kilojoules). This calculation will give you the energy generated by the solar panel in kilojoules per hour.
To convert watts to kilowatts, you divide by 1,000. Therefore, 500 watts is equal to 0.5 kilowatts. To convert minutes to hours, you divide by 60. So, 500 watts per minute is equivalent to 0.5 kilowatts per 60 minutes, or 0.5/60 = 0.00833 kilowatts per hour.
Kilowatts per hour is a unit of power. To calculate it, you simply divide the total number of kilowatts consumed by the total number of hours. This calculation is commonly used to measure electricity usage over time.

Every hour a 1 Megawatt turbine would produce 1,000,000 watts. That would be the equivalent of 1,000 Kilowatts.
Assuming an electricity rate of $0.12 per kilowatt-hour, running a 70-watt light bulb for 1 hour would cost $0.0084 or 0.84 cents. This calculation is done by converting watts to kilowatts (70W = 0.07 kW) and then multiplying by the cost per kilowatt-hour.

360 kilowatts would power about 1000 TVs, indefinitely. If 360 kilowatts of power were used, the energy used in 1 hour would be 360 kilowatt-hours.

The Battersea power stations A & B were both decommissioned with A being taken offline in 1975 and B taking offline in 1983. Therefore, the number of kilowatts an hour they produce is zero.
