How Many Solar Panels Do I Need To Power A Refrigerator?

Knowing the number of solar panels that power your refrigerator can be a daunting task. This is because there are many things to consider. The fact that a different refrigerator has different energy needs is common sense. The good news is that we can help you calculate the exact panels to run your refrigerator.

To do this calculation, you need a monthly electric bill. It will help you know your electricity consumption. Also, you should determine the number of hours you will receive sunlight in your area. During those hours, see the number of watts your solar panels can give out.

Calculate the electricity consumption in your refrigerator

First, you need to determine how much electricity your refrigerator consumes, on average. This information can be found on your monthly electric bills. The energy you consume varies from month to month, so you need an average number. Because it consumes more power in the winter, you can take one of the winter bills as the basis for your account. On your invoice, you will see how many kilowatt-hours of electricity you used during this month. Assuming this is the amount you use each month, divide it by the number of days in a month to see your daily energy consumption.

The amount of energy your panels produce.

You know how much energy your refrigerator needs each day. Multiply this number by 1000 to convert kilowatts to watts. Divide the amount by hours sunlight was received. Now you know how much energy the panels should produce per hour.

The number of hours of sunshine in your area

Solar panels depend on the shining sun. How many hours does your refrigerator have sunlight every day? Again, take winter days as a rule, because in winter, the refrigerator gets less sunlight. Suppose your refrigerator receives sunlight 6 hours a day.

Types of solar panels

The speed and efficiency with which solar cells can convert solar energy into electricity also help know how many solar panels you will need. Monocrystalline solar cells are instrumental. The amount of sunlight needed to generate a certain amount of energy is much lower than that of polycrystalline cells.

Also, depending on whether you are considering buying a high-tech solar kit or considering creating your panels from cheaper materials, prices may vary. Therefore, the number of solar panels that you can assemble into an array can vary, and their quality must also be evaluated.

Calculate the number of plates needed

The last information is the amount of watts that the panels can produce. When buying panels, pay attention to the number of watts written on your label. The average board produces around 100 watts, but the larger panels can produce more. If you want to buy 100 watts, divide the watts per hour you calculated in the last step by 100, and you’ll find out how many panels you need to power your refrigerator!


Of course, depending on the refrigerator’s needs, you may not always have to consume a lot of energy regularly. Especially if you are an environmentalist and learn to choose coolers that offer better jobs and consume less energy, you may be able to cut that number in half, or even less.
