Your appliances use more energy than you may realize it s amazing just how much power the average home uses.
What size solar system do i need to run a fridge.
7am 5pm 10 hours.
First we should assume a modern normal sized fridge running constantly.
According to energystar gov recent models sized in the 21 to 24 cubic foot range use about 560 kwh per year i want to use a monthly number so divided by 12 that s roughly 46 kwh per month from an upright modern refrigerator.
Solar kit to run tv laptop fridge mobile or lights hi and good luck.
Evening running fridge and lights.
5pm 9pm 4 hours.
Total consumption over 10 hours 13 5 amp hours.
You multiply the combined wattage of the solar panels by the number of hours sunlight they will receive per day.
It would help if you were a little more specific about the power consumption of your appliances but i will suggest the following.
Daytime running fridge only.
If you run your a c for 4 hours per day that means you would need 14 solar panels to cover 120 hours per month of use.
Estimate that fridge cycles.
When the air compressor on a refrigerator starts up it needs a surge of power that can use three times the normal running current.
1200 watts divided by 1 000 equals 1 2 kwh produced per day.
Now if you are going to set up your solar system yourself you will also need a charge.
In the day with just your fridge running.
This surge happens only for a split second.
A good rule of thumb is 4 hours.
300 times 4 is 1200 watts.
Hence it will not need to turn on as often.
After startup the fridge uses power according to the nameplate voltage and current.
