How Many Solar Panels To Power A Refrigerator

The average refrigerator found in the united states uses approximately 57 kwh per month while the average freezer uses 58 kwh for a combined total of 115 kwh.

How many solar panels to power a refrigerator. I harvest up to 8kwh per day with these panels. Solar panels are sold in varying sizes but a 100 watt panel is a commonly found size particularly for rvs. The solar panels have to be connected to a battery and inverter to provide power to your fridge. A solar power setup suitable for refrigerator use requires several devices in addition to solar panels.

Divide that by 30 kwh per month per solar panel and you get 3 8 solar panels. If we assume a 5 5 x 3 foot solar panel 200 to 250 watts would generate about 0 75 kwh per day it would take three of those panels to power a fridge that uses 46 wkh per month. Here are a couple panels that would be good options though with varying wattage levels. I actually did a hybrid approach.

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. Mounting the panels on the roof can be via manufacturer mounting solutions or you can make your own with rigid pvc. A device called a charge controller will smooth the flow of power from the panels to the battery.

Batteries are needed to store the power that the refrigerator will use at night or when clouds block the sun. A solar panel is only going to deliver charge during the sunlit hours and when not in shade so let s assume that we chase the sun all day by moving the solar panel around and get 8 hours of sunlight. They are wired 4 in series and 2 strings in parallel. The solar panels will charge the battery and keep it ready to supply power to your fridge.

The exact number changes depending on the specifications of the chosen panel model as well as the sunshine available at the project site. Let s look at a few other examples. That panel is rated at 100 watts at peak efficiency meaning on a 78 degree cloudless day at solar noon on the equator during the equinox. So at 6 65 amps for 8 hours a 120w solar panel can potentially deliver 53 2ah of chargeback into our battery 6 65amps x 8hours 53 2ah.
