Post: How to run a freezer on solar power

Table of Content

A recent study found that the average American family spends $1,500 a year on their electricity bill. This number seems high, but it’s actually quite low when you compare it to other countries. For example, in Italy, the average family spends $3,000 a year on electricity.

So, how can you save money on your electricity bill? One way is to run your freezer on solar power. Solar power is a renewable resource that is becoming increasingly popular as the cost of traditional energy sources continue to rise. Plus, it’s good for the environment!

There are a few things you need to know before you can start running your freezer on solar power. In this blog post, we’ll walk you through everything you need to know to get started.


Solar power is a clean and renewable source of energy that can be used to power a wide variety of devices, including freezers. While most solar-powered freezers are designed for use in off-grid or remote locations, it is possible to run a freezer on solar power even if you are connected to the grid.

There are a few things to keep in mind when running a freezer on solar power, including the size of the freezer, the type of solar panels being used, and the amount of sunlight that is available. In most cases, it is best to use a freezer that is specifically designed for use with solar panels, as this will ensure that the freezer is energy-efficient and will not put too much strain on the system.

If you are running a freezer on solar power, it is important to make sure that the solar panels are facing south and that they are not obstructed by trees or buildings. The amount of sun that hits the solar panels will directly impact how much power the freezer uses, so it is important to position them correctly. In addition, it is important to clean the panels regularly to ensure that they are able to absorb as much sunlight as possible.

What you need

In order to run your freezer on solar power, you will need:
-solar panels
-a solar charge controller
-deep cycle batteries
-an inverter

You will also need to size your system based on the power requirements of your freezer. To do this, you will need to know the power requirements of your freezer in watts. Once you have this information, you can determine how many solar panels and batteries you will need to run your freezer on solar power.

Solar panels

Installing solar panels is a great way to reduce your carbon footprint and save money on your electric bill. If you have a chest freezer, you can even run it on solar power. Here’s how to do it:

First, you’ll need to determine how much power your freezer uses. Check the manufacturer’s specifications or look for a sticker inside the freezer that lists the power consumption.

Next, you’ll need to calculate how many solar panels you’ll need to generate enough power to run the freezer. This will depend on the average amount of sun exposure your location gets, as well as the efficiency of the solar panels.

Once you have your solar panel system set up, you’ll need to connect it to your freezer. This can be done by wiring the panels directly to the freezer’s power cord or using a DC-to-AC inverter.

Now, you can enjoy the peace of mind that comes with knowing your freezer is running on clean, renewable energy!


An inverter is an electrical device that converts direct current (DC) into alternating current (AC).[1] The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.

A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry. Static inverters do not use moving parts in order to generate AC power.

Charge controller

A solar charge controller is a device used to regulate the charging of batteries from a solar PV array. It ensures that the batteries are not overcharged and damaged, and that the power is Released when the batteries are fully charged. The charge controller may also provide features such as low power disconnect (LPD), LED indication, and temperature compensation.


Solar-powered freezers usually come with rechargeable batteries. These need to be regularly charged in order to keep the freezer running properly. There are two main types of batteries used: lead acid and lithium ion. Lead acid batteries are cheaper but must be regularly maintained, while lithium ion batteries are more expensive but require less maintenance.

Refrigerator or freezer

A refrigerator or freezer is one of the appliances that consume the most electricity in a household. In the United States, refrigerators and freezers account for about 6 percent of total residential electricity consumption—an average of 936 kilowatt hours (kWh) per year, according to the U.S. Department of Energy (DOE). To put that in perspective, the average U.S. household spends about $107 per year on electricity for their fridge or freezer.

While there are many ways to save energy when running a fridge or freezer—like making sure it’s properly insulated and not overstocked—one of the most effective ways is to switch to solar power. Solar fridges and freezers are becoming increasingly popular as solar panel technology continues to improve and become more affordable.

There are two main types of solar fridges and freezers: absorption type and compressor type. Both use solar panels to convert sunlight into electrical energy, which is then used to power a cooling system.

Absorption type solar fridges and freezers use a gas absorption system similar to that found in many RV propane refrigerators. In this system, a liquid coolant is evaporated by heat from the sun, which then absorbs heat from the air inside the fridge or freezer, cooling it down. Compressor type solar fridges and freezers use a compressor, much like a conventional electric fridge or freezer, to cool the air inside the appliance.

While both types of solar fridges and freezers are effective, compressor type units tend to be more expensive than absorption type units. However, they also tend to be more energy-efficient and have shorter payback periods—meaning you’ll recoup your initial investment in a shorter amount of time.


Assuming you have a well-insulated freezer, you can expect to use between 1 and 2 kWh per day while running on solar power. Depending on the cost of electricity in your area, this could mean saving between $30 and $60 per month on your power bill. Of course, the actual amount you save will depend on the efficiency of your freezer, the amount of sunlight you get, and the size of your solar system.
