Looking for the perfect solar oven? We review 5 of the top solar ovens on the market right now. See how they compare, and find out which one we recommend and why.
Solar cooking has a long history and was first documented by Swiss physicist Horace-Bénédict de Saussure. He built the first solar oven way back in 1767. However, it hasn't always been a feasible method of cooking due to the lack of, or the cost of the constituent materials.
But, now that technology has caught up with the theory, solar cooking is actually a very effective and accessible method of cooking. The one thing you do need however, that isn't guaranteed for us all, is a steady supply of sunlight.
In this post we help you find the best solar cooker for your home with our solar oven reviews. We've chosen the top 5 solar ovens available right now, so you don't have to look any further.
We also look at the pros and cons of using solar ovens, how they work, and propose the key things you should look for when buying one.

So, how does a solar oven work?
A solar cooker works by "collecting" as much sunlight as possible, before converting this sunlight into heat. Importantly, the heat must be retained for the cooker to be effective at heating food.
A good solar cooker must excel in three key areas:
1. It must be effective at concentrating sunlight.
Using highly reflective materials that are set at particular angles, light can be "gathered" and focused on specific points. Solar ovens are so effective at focusing the sun's energy that some are capable of producing temperatures as hot as 400°C. This is easily hot enough to sear or grill meat.
2. It must be able to change the light energy to heat energy without much loss.
The cooking utensils that are used play a very important part in the energy transfer from light to heat. Dark colored surfaces are much more effective at absorbing light energy, and conducting and emitting heat energy. Pots and pans that are dark, thin, shallow, and with lids that seal tightly (to trap the heat) make the most effective containers for cooking with a solar oven.
3. It must retain heat energy well.
The cooker should isolate the outside air from the air inside the cooker. This reduces the heat loss. By using a glass lid on a pot or pan a process similar to the greenhouse effect can be produced that allows light energy in and traps heat.
This effect is common to those of us that use cars on hot days. When left in the sun the inside becomes extremely hot. This is because the initial light that enters the car has a shorter wavelength. After it is absorbed and reflected back (combined with some water vapor and CO2), it has a longer wavelength that will not pass through the window and remains trapped in the car.
Some ovens use a glass window or panel to produce this effect.
Why cook using the sun?
There are many reasons why using portable solar ovens is preferable over conventional methods. Solar cooking isn't without its flaws either, so it's important that we offer a balanced view. Here are some of the reasons for and against using solar oven.
The Advantages of Solar Cooking
- Your fuel is the sun's heat, which of course is free.
- It's amazing for the environment.
- Since there is no need for gas, electricity, or coal, there is less demand on resources. Reduce your carbon footprint (read our guide to wind turbines for even more energy saving tips).
- As there is no combustion, there are no nasty pollutants emitted into the atmosphere like carbon dioxide.
- Since they have to be used outdoors, they will not cause indoor temperatures to rise like conventional ovens do. This can save energy too.
- It's a healthier way to cook.
- No carcinogens or pollutants produced by smoke.
- No dangerous radio waves produced by microwaves.
- The moderate cooking temperature doesn't destroy the healthy nutrients in the food.
- Not relying on the power grid means that it can be used in times of power shortages.
- It's safe. No fire means no danger.
- It's very easy to cook with a solar oven.
- The even temperature of the oven makes burning food a very difficult task.
- It's versatile. Bake, boil, roast, or grill.
- It's great fun cooking outdoors!
The Disadvantages of Solar Cooking
- It relies on the weather. No sun, no cooking.
- It can take a bit longer than using a traditional oven.
- Cooking times will vary, depending on the time of day, and the time of year.
Before You Buy: Buyer's Checklist
Buying one of these for the first time will be a jump into the unknown for most people. Solar cookers come in a range of bewildering styles and sizes. Make sure you get the perfect model for your lifestyle with our buyer's checklist.
- What style of solar cooker is it?
Solar cookers generally come in three styles. There are those that heat a box (oven), those that directly heat a pot via panels, and parabolic cookers.
The models that use panels to heat a bowl or pot are generally the cheapest and most portable. They won't reach the cooking temperatures of other styles.
Those that use an oven style by heating an enclosed box retain heat well and are well suited to things like baking. They are great for meals that can be left alone for a couple of hours to cook.
Finally, there are the parabolic solar stoves. They use a dish shape to concentrate heat on a single point. They can reach really hot temperatures, but are more susceptible to the changes in position of the sun. They will need to be turned with the changing sun.
- What features does it have?
Ideally, it should come with a thermometer that enables you to measure how hot your oven is getting. This makes measuring cooking times much easier. It also makes cooking safer.
Solar cookers tend to need custom pots and pans that are built to retain as much heat as possible. Does the cooker come with utensils?
Also, if you plan on being on the move, does it have a carry bag and is it easily put away?
- How big is it?
Some ovens are more portable than others. Some state they are portable solar ovens, but in reality they are cumbersome to move anywhere. Check out the stats to see how much it weighs if you plan on traveling with it. Check out our Solsource solar cooker review for an example of a model that's not very portable.
Also check its cooking capacity. How many pots will fit at once? How big is the cooking area?
- Does it have a warranty?
Solar ovens aren't cheap so make sure it comes with a warranty to protect your investment. 30-day money back guarantees are becoming more common too, and offer no risk. Our solar ovens reviews make note of the warranty if available. The best solar ovens are well put together and come with decent warranties.
