Solar Refrigerator Vs. Solar Generator For Refrigerator

Solar energy is widely available and is one of the best ways to reduce electricity usage. The two best options for using solar energy are either choosing a solar refrigerator or a solar generator for the fridge. In this section, we'll discuss the pros and cons of solar refrigerators and power backup solutions and which one you should choose.

Solar-Powered Refrigerator

A solar-powered refrigerator runs directly on the sun's energy and includes photovoltaic panels. The PV panels work by converting sunlight into DC electrical power. The energy available is used to cool the refrigerator and keep the inner food safe and healthy.

People wanting to enjoy off-grid living, camping, or outdoor activities in areas with high sunlight can choose solar-powered refrigerators. However, it is suitable only for areas with long hours of direct sunlight.

In addition, power production is not uniform and depends on how much sunlight it receives during the day. Therefore, you need another power backup solution ready to charge the freezer during the night.


  • Solar-powered refrigerators use reliable and purest forms of energy; hence they can help you cut electricity bills.
  • It is energy efficient, and you'll need a 250-watt panel and a couple of deep-cycle batteries to power it.
  • As there is no need for fuel or gas, you don't have to spend money on its maintenance.


  • Power production is not uniform, as solar radiation is unavailable throughout the day.
  • It is not suitable for areas where the average solar radiation flux is low.
  • You'll have to install a large collector to produce high solar energy with solar refrigerators.

Solar Generator For Refrigerator 

Solar generator for refrigerators is a renewable and eco-friendly source of energy. That means you can power your appliances using solar energy even if no electricity is available. It converts sun rays into electricity and stores it in lithium-ion batteries for later use.

As solar generators are portable, they can be used for various appliances at home or outdoors. You can charge different electrical appliances and charge the solar generator simultaneously. This helps you to enjoy camping, outdoor activities, or off-grid living even when you are not connected to the electrical grid.


  • It is a solar power system. It converts solar energy to power and stores it in a lithium-ion battery of a portable power station. Hence, you can power up your refrigerator even at night.
  • A 1000-watt solar refrigerator generator can power almost 90% of electrical appliances, one to rule them all.
  • Pass-through charging converts solar to electricity and helps you power all appliances and charge the battery simultaneously.
  • As it uses solar energy, no fumes or harmful gases are emitted. Hence, it is safe to use indoors.
  • There are no maintenance costs associated with solar power generators. All you need to do is clean the solar panel with one clean cloth to improve efficiency.


  • Some large-capacity solar generators can be an expensive option compared to solar refrigerators.

    How Many Watts Does A Refrigerator Use?

    As there are different variants of refrigerators available on the market, the wattage required to run a fridge varies considerably. For example, a small refrigerator, mini solar cooler, or compact freezer uses fewer watts, whereas a large refrigerator needs more power.

    Read on to find out how much solar energy you need to run a refrigerator, the starting and running watts, and the different refrigerator types available on the market.

    What Is Watt?

    Watt (or W) is a unit of power used to quantify the energy transfer rate for a moment at a time. On the other hand, watt-hour (Wh) measures energy for a specific period. For instance, energy spent in one hour is termed a watt-hour.

    For instance, if a solar generator has a capacity of 200 watts, the watt-hour will be around 240 Wh. Meanwhile, a larger solar power generator of 1000 watts Pro will have a watt-hour of 1002 Wh.

    How Many Starting & Running Watts Refrigerator Use?

    Large appliances like freezers and refrigerators have electric motors present in them. That's why they need more starting watts than running watts. Starting watt is the amount of energy required to start an appliance; meanwhile, the running watt is the power any device needs to run for hours.

    The actual power requirement of a fridge will significantly depend on energy class, size, temperature difference, etc. Older larger units generally require 700-1000 running watts, while the starting watts are high (up to 2000-3000 watts). Meanwhile, newer units consume less energy and power.

    Generally, starting watts are always four times greater than running watts. Here is the simple formula to calculate starting watts.

    Starting watts = 4 * Running watts

    Let us assume that a refrigerator consumes 300 running watts. Here is how you can calculate the starting watts:

    Starting watts = 4 * 300W = 1200W.

    Here, 1200 watts are the minimum power you need to charge your solar refrigerator for hours. That said, you'll need to purchase a specific solar power generator that can provide more than 1200W power.

    Pro Tip: Before buying the best solar-powered generator for a refrigerator, it's vital to check the battery capacity, brand, and manufacturer. There are different solar power generators available in the market. Also, check the power station's features and ensure they have a robust protection system to keep the large appliance like refrigerator safe.

    How Much Solar Power Do I Need To Run A Refrigerator?

    One of the common questions homeowners ask while buying solar generators is: how much solar power do I need to run a refrigerator. The short answer lies in the type of refrigerator you have.

    For instance, if you have a large refrigerator that consumes around 800W, you'll have to purchase a solar generator with a high capacity. A solar power generator that can provide 800Wh (watt-hour) or more would be suitable for powering large refrigerators.

    Meanwhile, if you want to charge a mini cooler for camping or other outdoor activities, consider purchasing a solar generator with a capacity of 1000 watts. With a 1000 W solar generator, you can power different appliances with clean and green energy.

    Here are a few different types of refrigerators with their starting and running watts.

    • Large home refrigerators require 200-400 running watts and 800-1600 starting watts. This refrigerator is usually present in homes and businesses.
    • Average home refrigerators require 100-250 running watts and 500-1000 starting watts.
    • Small home refrigerators require 75-150 running watts, whereas starting watts are 400-600. An average solar power generator can keep your small power generator charged for long hours.
    • Mini coolers or fridges require 50-100 running watts and 200-400 starting watts. The portable refrigerator and solar generator combo will help keep your food cool and healthy.
    • Compact home or RV refrigerators require only 40-50 running watts, with starting watts around 80-120. These refrigerators are portable and perfect for camping and outdoor activities.

    Another question that solar generator buyers ask is: how many solar panels to run a refrigerator or freezer? The answer to this depends on your requirements and the wattage your electrical appliance consumes per hour.

    On average, the refrigerator takes around one to four solar panels to run. However, it will directly depend on the panel's solar generation capacity and the refrigerator's size. You can choose the number of solar panels depending on the power generator size and the estimated daily energy consumption.

    Here is the breakdown of how many watts different refrigerator types consume.

    "This is awesome! Bought it as a backup generator with 2 solar panels. When plugged into the power outlet, it charges really fast and even runs while being charged. This is a powerful "beast." It can run my big fridge for days. I have several Jackerys from 240 to 1500, and it gives me peace of mind for outages in a hurricane area where we are living without loud engines running or having to install anything on my roof. A little heavy, but where we store it that is not a problem. I recommend getting an extension cord with it. That allows some distance between the solar panels and the generator. Jackery is great. The customer service is incredible. They always have solutions. As I said. I have several of them. Never regretted the purchase. --Shannon"

    "In south Florida, we deal with a lot of power outages. And my work requires me to be out working when these occur. Though I have good generators, my wife is unable to operate them. This unit solves that issue. She runs a few cords and can restore enough power to abide till I can get the generators up. That's worth every penny to me.-- Dax Skywalker"

    One of the most vital features of Jackery solar power generators is pass-through charging. That being said, you can recharge and power appliances at the same time. With this, you'll never run out of power in any condition if you have a Jackery power solar generator with you.

    What Size Of Solar Generator To Power Refrigerator?

    The size of the solar generator to power the refrigerator will depend on multiple factors, including the refrigerator's age, features, size, temperature, amount of time it remains open, and more.

    Here is the simple mathematical formula to calculate the size of a solar generator for your refrigerator.

    Let us assume that you are using a solar generator 1000 pro that has a capacity of 1002 Wh.

    Working time = 1002Wh * 0.85 / operating wattage of your device.

    For instance, suppose your refrigerator consumes 200 watts of power. (You can find the power consumption of the freezer in the user manual).

    Then you can calculate the working time by substituting the value in the formula.

    Working time = 1002Wh * 0.85 / 200W = 4 hours.

    However, this does not mean you can power your appliance for only one hour. Due to the pass-through feature, you can even keep it plugged in for charging and power appliances simultaneously.

    Note: This is a rough calculation to determine the power consumption and working hours. If you're unsure which Jackery model will suit your needs, feel free to consult Jackery experts.
