A solar oven can even be built out of everyday materials. There are also cheap versions available on the market. What’s best about them is that they can be used to prepare just about anything which can be made with a standard oven or stove. You can bake bread, steam vegetables, and even roast meat in them. Further, solar ovens are usually placed outside the home; therefore they don’t take up any space in your kitchen. There are also some disadvantages to using solar ovens. They generally can’t be used on cloudy and rainy days.
They are most efficient during the hottest times of the day, such as in the late afternoon, after most people have already finished eating. But in this case, the oven can at least be used to keep food warm until evening.
