How many kilowatts are produced by 12 modules rated at 250W each?

To determine the total kilowatts produced by 12 modules rated at 250 watts each, you first calculate the total wattage. Multiply the number of modules by the wattage rating of each module:

12 modules × 250 watts/module = 3000 watts.

Next, convert the total watts to kilowatts since 1 kilowatt is equal to 1000 watts. To do this, divide the total wattage by 1000:

3000 watts ÷ 1000 = 3 kilowatts.

This calculation shows that the combined output of the 12 modules is 3 kW. Thus, the correct answer is that the total output produced by these modules is 3 kilowatts.
