Solar Powered Crock Pot and Solar Cooking


The chances are that you are spending a lot of money on electricity bills because you often prepare your meals with some hot plates. Perhaps you use gas to steam and cook for your family. Now, you feel like it is ripping you apart and keep wondering how to put a stop to it. Well, solar powered crock pot is the solution to this challenge.

This means you can use solar heat or energy to cook your regular meals, such as rice, beans, meat, vegetables, stew, etc. With this innovative technology, you can be sure of keeping your electricity bills considerably low.

A typical solar crock pot is similar to your usual kitchen pot, but possesses some electrical connections and a regulator. Nevertheless, they present different features, as they are made by different companies. While many families have known about this innovative cooking method for some time now, tens of thousands of people are just starting to know about it. Just before discussing the details, let’s understand its basics.

How Solar Cookers Work?

Let’s start with how it works. Essentially, this technology can be used in two ways. But before getting to that, there is a general principle behind it, which is converting sunlight (solar energy) into heat energy. Afterward, the heat energy will be used for cooking. In order to assemble the system, you will need to have an outdoor solar panel with a reflective surface exposed to the sun to absorb sunlight and convert it into solar energy.

In other words, the conversion happens because photons (light particles) are always in constant interaction with the molecules in a substance. When heat energy strikes the molecules, they will get excited. The excitation will result in the energy that is being given off.

According to conduction mechanism of heat transfer, dark surfaces tend to absorb heat more than light ones. So, the best material for that purpose is an aluminum foil or a mirror. However, this mostly applies to the second method. As said before, solar-enabled cooking is done in two ways.

Indoor or Indirect Heating Method

For this first method, you will need some batteries. When solar energy is channeled into the battery, it will charge it. Typically, you can use your 45 kw car batteries for this purpose. It will enable you to generate enough energy to cook your meals as fast as you possibly can. The batteries serve as the powerhouse for storing the energy needed for cooking your meals. However, before getting to this point, you must already have stocked your solar powered crock pot with the raw food you wish to cook. Next, connect the batteries to a charge controller.

From the charge controller, the power is fed into a socket. Once you notice that the socket is powered, then you will have to plug your inverter to the socket. Generally, the function of an inverter is to convert direct current (DC) to alternating current (AC). Finally, the pot is connected to the inverter. The advantage of this technique over the next one is that you don’t have to cook your meals in an open place.

Also, this technique will enable you to decide how fast you wish the process to go. This means that you can get a bigger solar panel, inverter and batteries to expedite the process. Depending on the capacity of the system, you could use more or less 5 hours to cook your meat.

Outdoor or Direct Heating Method

Alternatively, you can have solar cooking or solar oven set up outside of your home. This is the most common method and you just need a normal cookpot for this. You will need a solar cooker panel, a material made of carton and aluminum foil for absorbing solar energy and channeling it into the pot. Yes, it is specifically meant for this purpose! It is easy to unfold and set up. To ensure that, it is better to cook during a hot day during the summer.

Next, put out your cooking bag, which comes with spacers. The spacers are candle-like PVC sticks used to separate the bottom of the pot from the cooking bag. When you have opened and set up the mechanism, position it in a way that it can directly face the sun. Afterward, you cover the cookware with the cooking bag and separate the edges of the pot with the spacers. Then seal the opening of the cooking bag and pass it through openings of the solar crock panel.

With this method, you will need a black cookpot because black materials absorb and retain heat better. While you are using this, it is advisable to respect the temperature of your meal, as it will help you monitor the progress of the process. This technique takes a lot of time as you could spend 7-10 hours cooking your food. In other words, you don’t use it when you are in a hurry.

Where is Solar Cooking Used?

There are certain countries where solar cooking is ideal because they have high temperature year-long, that enable the meals to be cooked really fast. Generally speaking, solar cooking can be used in almost all the countries you can possibly think of. If you live in the United States, U.K., anywhere in Africa, South America and the rest of Europe, you would not have a challenge using this solar-powered technology.

The good thing is, in countries like the United States, Afghanistan, China, India and Argentina, many people are already using it. While you can use it in Russia, you may have a little challenge doing so in the middle of the winter season.

With respect to Africa, this cooking method is steadily making inroads across the continent. In Kenya, for instance, local communities are employing insulated baskets with high heat-retentive capacity to trap sunlight. As the users pointed out, these baskets are capable of retaining heat when the intensity of sunlight has reduced. In turn, this significantly tackles the challenge of sunlight fluctuations. In 2017, Reuters reported that over 1,500 households in Kenya’s Busia County banked on solar energy to put cooked meals on their tables.

Well, the narrative isn’t different in Zambia, a country in southern Africa. In rural Zambia, the locals are turning to solar-enabled cooking as an alternative to hot pots and firewood. Given that the country has intense sunshine in face of hard-biting energy crises, SunFire solar ovens, Zambia’s popular solar-cooking products, have become a household brand. The manufacturer, SunFire, leverages the outdoor or direct heating method (described above) to design, build and sell the products.

In Uganda, the locals’ accounts show a growing trend of solar-powered cooking across the continent. Indeed, it is the perfect alternative to fossil sources of cooking energy, such as firewood, charcoal and dung. Well, Kawesa Mukasa, head of the country’s solar research association, disclosed that they’ve developed and sold over 250 solar crock pots to the people. The type of solar crock pot distributed by the company works like the Fresnel lens (to be discussed later).

Looking at it from another perspective, there are many homes that are fed up with spending too much money on cooking their meals, as we explained earlier. This cooking method offers them a great alternative. Keep in mind, however, that it doesn’t completely eliminate the method you are used to now. Instead, this technique just serves as a complement. Often, it is deployed to refugee camps to cut cooking cost for a large number of displaced people. For instance, it was used to cook for over 40,000 families in 2005 in Darfur, South Sudan.

Pros and Cons of Solar Cooking

So far, our emphasis has been on how, where and why solar cooking is used. Today, the technology is increasingly gaining traction because people appreciate its benefits. While it has some attendant benefits, it also has some disadvantages. This part of our guide will put those two into perspective.


  • Unlike other cooking methods where you must replenishing your fuel, solar cookers involve one-off payment, thereby making it cheap

Main Types of Solar Cookers

There are many solar cookers on the market. In this part of the guide, we will break them down one after another.

Solar Panel Cooker

This type is the simplest and most affordable one out there. You will love it because it doesn’t generate too much heat when in use. By concentrating sunlight into the cookware through its curved surface, it cooks the content of the pot. Just follow the above-mentioned explanations given in the second method to grasp how it works. More importantly, this solar cooker is affordable and simple. Shield it from the wind because it is not insulated. Also, it’s very likely that it can heat up to 65 degrees Fahrenheit and you need only 2-4 hours to cook. Feel free to use it to cook anything: soup, stew, beans.  

Basic Box Solar Cooker

Unlike the Solar Panel Cooker, this type is constructed with a single reflector and an opening capped by a pane of glass. With the single reflector, sunray is concentrated around a dark-colored pot, which is placed inside the box. With this simple setting, you can use it to cook your meals. It is commonly used in India and can absorb and retain temperature as high as 392 degrees Fahrenheit. Depending on the size, you can place many pots in one.  

 Solar Oven

By principle, Solar Panel Cooker and Solar Ovens have a lot in common. However, the latter use an insulated box to ensure that heat is retained. Well, they are perfect for baking, which explains why the panel is considered as an “Oven.” When sunlight makes impact on the box, it will then generate heat that would be trapped.

The good thing about this type of solar-powered cooking is that it is capable of reaching temperatures as high as those methods used for traditional cooking. Typically, it can reach 400 degrees Fahrenheit. Again, it is important that you use a dark cookware or bakeware, as they tend to absorb and retain heat more than others.


Parabolic Solar Stove

Just like the ones that came before it, Parabolic Solar Stove primarily channel its sunray to the cookware and can also generate a temperature up to 450 degrees Fahrenheit. Interestingly enough, it is capable of heating faster than the traditional cooking methods. Moreover, it can cook from sunset to sunrise, including subzero temperatures.

Fundamentally, Parabolic Solar Stove concentrates light on the bottom of the pot, helping it cook meals a lot faster than others. Regarding its panel, it is shiny, lightweight and durable. If you love to grill, fry and steam, this type is your best bet, as it is fast and hot.

Fresnel Lens

This one takes cooking to the next level by completely eliminating the idea of concentrating sunray on the cooking pot. It is designed in a way that the solar energy passes through the lens to heat up the pot (food). In some cases, it is made of reflective rings that channel sunray onto the pot. Although the rings tend to be similar to the parabolic reflector, they are horizontally extended.

However, it is designed in a way that the diameter of the rings is bigger, thus allowing heat to get to the cookpot easily. With the intense heat generated from this mechanism, you can boil and fry anything. It is also easy to assemble. With intense radiation, you have to always keep close tabs on your meals.  


Evacuated Tube Cookers

Last but not least, these cookers can generate up to 550 degrees Fahrenheit of heat or even more. They can be used for cooking bread, vegetables and dessert. While they share lots of similarities with the types reviewed earlier, they are capable of working well even when it’s cloudy. GoSun, the leading solar crock pot maker, is pioneering this innovation. From findings, it heats food with the aid of the tube, so there is no need for preheating the tubes.
