Can I Run A Refrigerator with Solar Power?

Yes, solar power can power various household appliances, including a standard refrigerator, a mini-fridge, or an RV refrigerator.

It would be best to have solar panels, a battery, an inverter, a charge controller, or only a solar generator to use solar power. Solar panels can transfer sunlight into electricity, but there is a power station or battery to store energy and power a refrigerator. A solar generator could be the best option to charge the refrigerator with solar power, which combines solar panels with a power station.

Solar energy  is an excellent resource that is gaining in popularity daily. Solar power is never exhausted because it is a renewable energy source. Solar energy is environmentally friendly. It emits no carbon dioxide. In addition, solar energy can lessen your reliance on the utility and lower your electricity bill.

Although you can use solar power to charge a refrigerator, it is essential to know how many watts a refrigerator uses and how much solar energy is required, keep reading, and you will learn the answer.  

How Many Solar Panels Do I Need to Run A Refrigerator?

How many solar panels to run the refrigerator? Solar panels are an effective method to lower your electricity bill and help the environment. However, how many solar panels are needed to fuel a fridge? Depending on the size of your refrigerator and the amperage of your solar panels, the number of solar panels required will vary.

how many solar panels to power a refrigerator

Before determining how many solar panels are required to power a refrigerator, you must calculate the following:

  • How many watts does a refrigerator use?
  • How many watts do solar panels generate?
  • How many peak sun hours do you receive?
  • How much solar power does your refrigerator need?

How Many Watts Does A Refrigerator Use?

Most refrigerators in the United States include an EnergyGuide label that estimates their Annual Energy Consumption (kWh/year), which can be used to calculate their daily energy consumption (kWh/day).

For instance, this refrigerator's label indicates an "Estimated Annual Electricity Use" of 600 kWh. To calculate the daily energy consumption of this refrigerator, we divide its estimated annual energy consumption by 365 (the number of days in a year):

Estimated Daily Energy Consumption = 600 kWh ÷ 365 = 1.644 kWh/day = 1644 Wh/day

It is the easiest and quickest method, but you can also calculate your refrigerator's energy consumption using the manufacturer-supplied electrical specifications.



Annual Energy Consumption

Daily Energy Consumption

Small Fridge

4.5 Cubic Feet

237 kWh/year

650 Wh/day (0.65 kWh/day)

Middle Fridge

12 Cubic Feet

312 kWh/year

850 Wh/day (0.85 kWh/day)

Large Fridge

27 Cubic Feet

728 kWh/year

2000 Wh/day (2 kWh/day)

How Much Energy Does A Refrigerator Use?

Here is a reminder of the distinction between electrical power and electrical energy to avoid confusion:

Electrical power: measured in Watts (W) or kiloWatts (kW), represents the electricity consumption rate.

Electrical energy: measured in Watt-hours (Wh) or kiloWatt-hours (kWh), electrical energy is consumed over a given period. Power (Watts or kiloWatts) and Energy (Watt-hours or kiloWatt-hours) have the following relationship:

Energy Consumption (Wh) = Power Consumption (Watts) x Duration of Use (Hours).   

For instance, if you have a 500W refrigerator that you use 24 hours per day, the daily energy consumption would be 500W x 24H = 12000Wh (12kWh).

As previously explained, a refrigerator's power consumption is the rate at which it consumes electricity. While older refrigerators can consume up to 700 Watts of power, newer, more energy-efficient models only consume 150-300 Watts.

You can find the power consumption (Watts) of your refrigerator on the manufacturer's nameplate or calculate it using other electrical specifications, such as its Amperage (Amps) and Voltage (Volts).

How Long Does A Refrigerator Run?

Refrigerators have operating cycles (Duty cycles), which means they do not operate continuously.

The compressor, the primary electrical component in a refrigerator, cycles ON and OFF to maintain a constant temperature within the appliance. The refrigerator's compressor must work harder to maintain the desired temperature whenever the ambient temperature rises, which causes power surges and increased duty cycles.

How Many Watts Does A Solar Panel Generate? 

First, determine your solar panels' power yield. Under perfect conditions, a solar panel can provide up to its rated electricity. However, the actual production will vary. The actual wattage produced by your solar panels depends on several factors, including:

- Accessible sunlight

- Temperature

- Orientation and angle of your solar array

- Panel type (polycrystalline, monocrystalline, thin film)

- Solar panel productivity

All of the above factors affect the amount of electricity your solar panel will generate. Also, observe that some conditions can vary substantially throughout the day.

How Many Peak Sun Hours Do You Have? 

In the solar industry, W/m2 (Watts per square meter) is the standard unit for measuring sunlight (Solar irradiance). Before a solar panel is assigned a Wattage rating, it is subjected to a series of tests known as "Standard Test Conditions" (or STCs for short).

These STCs contain a standard testing condition that replicates the amount of sunlight a solar panel would receive in ideal conditions: 1000 W/m2 (1 kW/m2).

peak hour graph
Data Source: Alternative Energy Tutorial

Under these ideal conditions, a Peak Sun Hour is the energy the sun receives in one hour. Peak Sun Hours help us determine the amount of energy solar panels could produce in a given location.

Daily Energy Production (Wh) = Wattage of Solar Panels x Daily Peak Sun Hours

Reversely, and more importantly, for our purposes, you can use your region's daily peak sun hours to establish the size of the solar panel you require if you know how much daily energy the solar panels generate:

Wattage of Solar Panels = Required Daily Energy Production / Peak Daily Sun Hours

For instance, if you need to generate 600Wh of energy per day in an area that receives six hours of optimal sunlight daily, you will need a 100-Watt solar panel. (600Wh / 6 Sun Peak Hours) = 100W.

How Much Solar Power Does A Refrigerator Need? 

To calculate the amount of solar energy required to operate a refrigerator, divide the refrigerator's daily energy consumption (in Watt-hours) by the number of Peak Sun Hours you receive daily, then multiply the result by 1.15 to account for system losses.

Solar Power Needed = (Estimated Daily Energy Consumption / Peak Sun Hours) x 1.15

For instance, if your refrigerator consumes approximately 2000Wh of energy per day and receives 5 hours of peak sunlight daily, you will need (2000Wh / 5H)*1.15 = 460W of solar power to operate your refrigerator.

What Size of Solar Panels Do I Need to Run A Refrigerator?

To determine what size of the solar panel to power a refrigerator, you must first determine how many amps the refrigerator draws. Multiply the voltage of your refrigerator by the amps it consumes; most refrigerators use approximately 13 amps. It will provide the wattage your refrigerator requires. Next, The number of solar panels necessary can then be calculated by dividing the wattage by the voltage.    

Once you have determined the energy requirements for your refrigerator and any other electronic devices you intend to power with solar energy, you can assemble the appropriate solar panels. Choosing solar panels is relatively straightforward, mainly if you know your energy needs.

  1. How to make my refrigerator more energy efficient?

It is possible to reduce your refrigerator's daily energy consumption. These suggestions will make your refrigerator more energy-efficient and reduce your monthly electric bill:  

  • Keep the refrigerator well-stocked. When a fridge is empty, it requires more energy to chill itself than when it is complete.   
  • From time to time, defrost your freezer; this enhances the appliance's efficiency. When frost reaches a thickness of 1/4 inch, it is time to get to work.
  • Cover all liquids and stews placed in the refrigerator. They emit moisture, which increases the load on the refrigerator's compressor.

    Final Thoughts

    The refrigerator is the most demanding working household appliance. It preserves our food frozen and fresh 24 hours per day, seven days per week. Since the refrigerator accounts for between 5 and 10 percent of your annual electricity bill, running it on solar power is highly enticing.   

    This detailed guide will help you to figure out how many solar panels you need to run a refrigerator, how many watts it uses, and how much solar power it requires. Jackery Solar Generators combine solar panels with power stations to power your refrigerator with high capacity.
