There are ALOT of factors to consider. Where is the house located geographically, what is the average electrical bill, are there cheaper/more efficient technologies that can be put in place first like Solar water heating or CFL lighting etc.
for instance a 2000sqft home with Solar water heating, cfls and other energy saving devices may be able to reach a net $0 energy consumption with a 5KW system, if those devices were not installed then that same 5KW may only represent 25% or 30% of the required energy.
The best bet is to find someone who Specializes in Solar Home Makeovers and ask them for an estimate.
Multiply the horsepower by a factor of 0.746 (approximate) to obtain the equivalent power in kilowatts.
You do not. Kilowatt hours is a measure of energy and a megawatt is a measure of power. The two measure different things and so one cannot be converted to the other. It is like asking how you can convert feet (distance) into miles per hour (speed).
5000 watts is equal to 5 kilowatts because 1 kilowatt is equal to 1000 watts. So, to convert watts to kilowatts, you simply divide the wattage by 1000.
Total power output of the sun: 3.86 x 1023 kilowatts (386,000,000,000,000,000,000,000 kilowatts) Total solar power received on Earth: 1.74 x 1014 kilowatts (174,000,000,000,000 kilowatts) Solar power falling on 1 square meter of ground: 750 watts (0.75 kilowatt) Output of a 1 square meter solar panel: 120 watts (0.12 kilowatt)
To convert kilowatts to watts, multiply by 1000. Therefore, 75 kilowatts is equal to 75,000 watts.
Use the formula: energy = power x time. If power is in watts, convert it to kilowatts. Then you have: power (in kilowatts) x time (in hours) = energy (in kWh). Of course, you'll first need to figure out how much power the device - whatever you are talking about - uses.
Power is obtained using the equation: Power (Watts) = Voltage (Volts) x Current (Amps) To convert to Watts to Kilowatts (kW), simply divide by 1000 (or shift the DP left by 3 places). eg. 5000W = 5kW Bringing these together: Kilowatts = ( Volts x Amps ) / 1000
These are two different values. kWh is the amount of kW that are used in an hour. To convert kW to kva use the same formula but leave out the pf (power factor) component.AnswerFirst of all your should realise that power is measured in watts (or kilowatts), not in kilowatt hours! A kilowatt hour is an unit of measurement for energy, or work done, NOT power! So your question doesn't actually make any sense!Furthermore, a kilovolt ampere is the unit of measurement for apparent power, and it should be written as 'kV.A', not 'kva'.So you cannot convert energy in kilowatt hours to apparent power in kilovolt amperes, as we are talking about two completely different quantities! It's like asking "How do you convert miles into kilometres per hour?" That's what I mean by your question not making any sense!The first answer needs correction, as the kilowatt hour is not 'the amount of kilowatts used in one hour'. You do not 'use' kilowatts, as kilowatts is simply a rate. So the correct definition is that a kilowatt hour is the amount of energy used in one hour, at the rate of one kilowatt.
To convert brake horsepower (bhp) to metric units, you can use the following conversion factor: 1 bhp is equal to approximately 0.7457 kilowatts (kW). Multiply the bhp value by 0.7457 to get the equivalent power in kilowatts.
The components of a watt are amps multiplied by volts. IE. w = v x a. So you can transpose the formula to arrive at the correct answer. Kilowatts, are watts to the power of three. IE. 3000Watts = 3kW
You can't. 123 cc is a volume, horse power is power. If you know the output of a 123 cc engine, either (i) you already know its horsepower, or (ii) you convert kilowatts to horsepower by hp = kw/0.746.
To calculate the power consumption in kilowatts, first convert the current from amperes to kilowatts using the formula P = V x I. In this case, P = 120V x 1.07A = 128.4 watts. Then, convert watts to kilowatts by dividing by 1000: 128.4 watts / 1000 = 0.1284 kW. Therefore, a 120 volt 100 watt light bulb pulling 1.07 amps uses 0.1284 kilowatts of power.
