A mini refrigerator uses about 70 watts per hour or 0.07 KWH.
Therefore it uses about 24 times 0.07 KWH, or 1.68 Kilowatt Hours per day.
There are varied sizes of "mini refrigerators" and varying degrees of
insulation, so the wattage may vary from 40 watts per hour to 100 watts per hour or .96 KWH to 2.4 KWH per day
It depends on the size of the party. But a normal kitchen refrigerator takes about ¼ - ½ kWh per day.
My refrigerator is a normal one in the kitchen and it uses about 0.4 kWh each day. If a party refrigerator is 2 x as big it would use 2 x as much energy each day.
When the motor is running it uses the same power - number of watts - all the time. To find the energy used (in watt-hours) you multiply the watts used by the total time in hours. So if it uses 500 watts and is on for 3 minutes each hour, it uses 500x3/60 watt hours each hour, or 600 watt-hours in one day.
A middle classed home uses 9.6 mega watts a year (9.6 million watts) divide that by 365 and you'll get the answer.AnswerA watt is an instantaneous measurement of the rate at which you consume energy. Therefore, there is no such thing as 'watts per day'. You should be asking 'How many kilowatt hours does a house use in a day?', because a kilowatt hour is an unit of energy.
it depends on the load.. If you are using a total load of 1000 watts for 1 hour your energy consumption is 1 unit
To obtain amps from watts a voltage must be given.

$67.74 using 120 volts. Great job on the math, but a refrigerator doesn't run 24 hours a day. It runs off of a thermostat and has periods of off/on. It depends on the climate in which you live (i.e. how hot it is in your house) as to how often your refrigerator kicks on. Its actually really hard to keep track of. If you buy a "Kill A Watt" meter, you can plug your fridge into it and it will tell you how many watts the fridge has actually used in a day. It probably only runs a few hours total each day!
Mine says 2W and 220-240 volts on the bottom, so I assume 2 watts.
The watt is a rate of delivery or use of energy (1 Joule per second) Anything called watts per day means an increase in power per day. (100 watts first day, 200 watts second day, 300 watts third day etc). I'm sure you don't mean that. Direct ("normal" ) sunlight that falls on a square metre is up to about 100 Watts so you'll never get more power from that even with 100% efficiency. Consult the brochures. Probably a few tens of watts per square meter. Energy per day is watts x time-of-sunlight (direct, near 90 degrees). Which will be Joules. 3600x1000 Joules equal 1 Kilowatt-hour, sometimes called "1 unit".
how much units cosumed by 15 watts cfl ina day
That is a believable claim. 399 units per year or 1.09 units per day is an average power of 0.045 units per hour, equal to 45 watts. In practice the refrigerator pump probably take about 5 times as much when it's running but the thermostat keeps it turned off most of the time. My ordinary kitchen refrigerator has used 1.3 units in 3½ days, an average of 15 watts.
There are many factors that will come into play here. 1. Where do you live? The region will determine how much sun, on average, you will receive. In Wisconsin we get about three hours of full sunlight each day. Temperature also is important. The warmer your location, the worse solar panels work. If your area is over 85 degrees, your panels will not produce as well. 3. What size panels? Panel ratings are made using short circuit current and open voltage peaks. In th real world you can expect about 80% from a panel. My 75 watts panels will peak at 56 watts on a sunny and cool day. In the summer, the panels degrade to about 48 watts. 4. What is the power needed for your unit? If you draw is, on average, 200 watts you will need to cover 200 watts. Let's do the math now. To do so you take the 200 watts times 24 hours. So we will need to collect 4800 watts a day of power. Assuming you live near me you will have three hours of equivalent full sunlight to do this with 56 watts an hour from each panel. That comes out to 168 watts a panel per day. The minimum number of panels for my area would be 29. This should give you enough for all but the warmest days to cover your unit.
60 days
(600 watts) x (12 hours per day) = 7.2 kilowatt-hours per day
