Solar energy is a renewable, sustainable form of energy. Obtaining pure and clean power from the sun is a viable solution that has the potential to benefit the environment, while also providing hope for the future.

You are helping the environment by utilizing the sun through 100-watt solar panels. These solar cells are also mobile, comfortable, and cost-effective. But can a 100-watt solar panel run a refrigerator?

A 100-watt solar panel can only power a refrigerator for a brief period and it will require a power pack. On average, 100 watts of solar panels can yield 400 watt-hours of electricity a day. A refrigerator with a freezer requires 2000 watt-hours per day.

In this article, we will go further to explain whether or not a 100-watt solar panels can power a refrigerator. You’ll learn how many watts are required to generate electricity for a refrigerator and some extra types of equipment!

Let’s get started!

Can A 100-Watt Solar Panel Run a Refrigerator?

Operating a refrigerator on a 100-watt solar panel may be difficult. Fridges require a consistent energy supply to keep your food safe and fresh.

The best part is that if you get the suitable power criteria estimations and some associated equipment, you ought to be able to operate your fridge on solar power.

How Much Energy Can a 100-Watt Solar Panel Generate?

Calculating the energy output of solar cells can be difficult. A 100-watt solar panel, on average, generates 400 watt-hours each day.

You may also be curious how many ammeters a 100-watt solar panel constitutes.

A 100-watt solar panel generates approximately 5 amps of electricity per hour. However, this is only true in direct sun.

What is The Yield of a 100-Watt Solar Cell on a Foggy Day?

Even on a foggy day, solar panels continue to function. On a foggy day, the yield of a 100-watt solar panel is assumed to be approximate – 25% of the standard power produced by the solar panel.

If you would like to run your kitchen with 100-watt solar panels, you must charge your capacitors on a foggy day.

How Many Watts are Required to Run a Refrigerator?

A typical modern refrigerator may require between 80 and 300 watts, although some small domestic refrigerators have a minimum power of 65 watts.

What is Required to Supply a Refrigerator With a 100-Watt Solar Panel?

You may require some extra devices to successfully operate a refrigerator with 100-watt solar cells. Just ensure they are compatible with your refrigerator design.

Batteries, inverters, and solar charging regulators are extra hardware for your solar array.


Batteries are an integral part of your solar arrangement, and your fridge will most likely not run dependably without them.

The amount of power generated by your solar panels may vary depending on the amount of sunlight it absorbs. When you need to operate your fridge in the dark or on a foggy day, batteries prove to be very helpful.


An inverter is an electronic equipment that transforms direct current (DC) electricity from batteries to alternating current.

An inverter is needed because AC power is delivered to homes and businesses via the main public power grid. Batteries, on the other hand, only store direct current power. This must be converted to alternating current.

The inverter you utilize should be ten times more potent than the actual number of watts required to operate your refrigerator.

Inverters are not required for other modest home devices or 12v compressor refrigerators.

Frequently Asked Questions

Can 100-watt solar panels supply a recreational vehicle?

A 100-watt solar panel with 4 hours of peak sunlight can produce 400 watt-hours each day. You’d need up to 3 100-watt solar panels to drive the RV.

What Appliances Can a 100 Watt Solar Panel Power?

You can reap some benefits by connecting a 100-watt solar energy system to deep cycle batteries. It will enable more advanced programs. Let’s look at the list below to see applications of a 100 Watt solar panel you can use.

  • Charging a smartphone
  • Light-emitting diodes
  • The ceiling fan
  • The laptop
  • Lighting and lamps
  • Router WiFi

How much solar energy is required to power a fridge?

Split your fridge’s daily average energy usage by the total count of peak hours of sunlight in your area to determine the amount of solar power required to run it.


You now understand that a 100-watt solar panel produces 400 watt-hours of power each day. A standard refrigerator with a freezer requires 2000 watt-hours per day to operate.

A 100-watt solar panel could be sufficient to activate a refrigerator for a short time, but it will require a power pack. In summary, a 100-watt solar panel would not be capable of creating sufficient routine power to keep your food fresh constantly.

You may require approximately three to four 100-watt solar panels to complete the task. Four 100-watt solar cells will most likely be the most reliable method for the refrigerator to work efficiently.
