When it comes to cooking, electricity and natural gas are typically the most commonly used energy sources. Both types of energy have limited mobility, and when they do become mobile and portable, it comes with added risks. Butane Gas stoves, the portable version of your gas stove, are often known for their risks for explosions and are even banned in some countries.
Portable induction stove, while safer to some extent, also provides risks for EMF radiation. Besides, as with any electric device, the need for it to be plugged in or charged can be a hassle and inconvenient when you are going portable.
A solar cooker, AKA a solar oven can be the answer for your portable cooking needs for outdoor activities such as camping, hiking, remote adventures , long expeditions, and many others. It even works well for cooking at home as a cleaner cooking method , more efficient energy usage , and almost zero associated dangers.
Before we get started with how to choose your solar oven, let's discuss a bit about the basics of solar cookers.
In its fundamental principle, a solar cooker concentrates direct sunlight energy to heat food or drinks, and can cook or pasteurize food. The temperature can be as high as 750 °F (400 °C), so it can grill or sear perfectly on a sunny day.
Many methods can be utilized to achieve the concentration of sunlight. However, three remains the most popular methods of solar cooking. They are:
This method utilizes reflective panels, the panels are shaped so that the cooking vessel will receive sunlight in a concentrated form from the panels. It can come in many shapes, just like the photo above.
Generally, the cooking vessel should be darkened, and then enclosed in transparent plastic bag or glass bowl.
This is one the most commonly used method, the design is roughly based on a modern conventional oven. The cooking utensil is placed inside a 'box', that is insulated to trap solar energy and store it as heating to cook.
The box is usually covered with transparent material (glass/plastic) to filter out the ultraviolet rays. Only infrared rays, which are utilized to heat the cooking utensils will pass through the glass/plastic, which would allow the box store the solar rays into heat to cook.
Sometimes reflector panels are added to increase the cooking power, to further concentrate sunlight to optimize heating.
This one is a bit more sophisticated, and complicated to build. As the name suggests, this method uses a parabolic-shaped reflectors to concentrate all the sun light to a single point. As a result, the parabolic cooker reaches higher temperature quicker than any other current method.
However, since the sunlight is extremely concentrated, the amount of food, both in quantity and types, are limited.
After we understand the basics, and these three different types of solar ovens, let's move on to how you can choose your options when selecting one.
Now that we have a bit more understanding of the 3 above types of solar cookers , let's take a look at what the difference between them are.
Brand and quality will be a factor, one of the biggest factors is the time frame of cooking. In general, panel cookers are the slowest at gaining heat, followed by box cookers, and the fastest being the parabolic cookers.
Price-wise, they also follow the similar order, with panel cookers being the cheapest and parabolic cookers being the most expensive.
Here are some of the notable products available on the market today, in no particular order:
Known as the ultimate solar appliance. SUN OVEN is one of the leading manufacturer of solar cookers, and not without a reason. Their Global Sun Oven is the best-selling solar oven in the world, now discontinued and replaced by the newer All-American Sun Oven.
Both the Global and All-American Sun Oven utilized the box cooker method, so it's a bit bulky and will require a bit of a space, but it can generate heat in a fairly quick timeframe.
