How many solar panels to run a refrigerator.

The solar panels will charge the battery and keep it ready to supply power to your fridge. There are more variables than you might expect. A typical inverter offered at discount stores or home centers provides 1 500 watts continuous ac power and 3 000 watts of surge power. If we assume that each solar panel will average about 75 percent of four hours of direct sunlight each day it would take about three solar panels to power a fridge.

Batteries are needed to store the power that the refrigerator will use at night or when clouds block the sun. Please assume my daily amp. Inverter if you have an inverter it will need to handle about twice as much as the maximum load so a 2 200w inverter should work for this example. A solar power setup suitable for refrigerator use requires several devices in addition to solar panels.

This unit should run a typical 16 cu. A device called a charge controller will smooth the flow of power from the panels to the battery. I harvest up to 8kwh per day with these panels. Mounting the panels on the roof can be via manufacturer mounting solutions or you can make your own with rigid pvc.
