FIELD OF THE INVENTION
The present invention relates to a solar system. The present invention particularly relates to smart green solar oven which utilize sun heat for maintaining constant temp in oven by circulating heat energy and which are more efficient in any weather conditions.
BACKGROUND OF THE INVENTION
As a matter of life or death, the preservation of food has long been one of our most pressing problems. Almost from the very beginning of our existence on earth, it became necessary for us to find ways of preserving food during seasons of abundance in order to live through seasons of scarcity. It is only natural, then that man should discovery and develops such methods of food preservation as drying, smoking, pickling, and salting long before he had any knowledge of the causes of food spoilage.
These rather primitive methods are still widely used today, not only in backward societies where no other means are available but also in the most modern societies where they serve to supplement the more modern methods of food preservation. They are not universally adaptable for the preservation of all types of food products. Furthermore, the keeping qualities of food preserved by such methods are limited as to where a product is to be preserved indefinitely or for a long period of time; some other means of preservation ordinarily must be utilized.
The preservation of perishable commodities, particularly foodstuffs, is one of the most common problems in rural area where electricity source is not available. Conventionally many solar heaters were used to preserve food or for heating water but during summer that hot water is not able to utilize or during winter or cloudy weather efficiency of solar will be less.
Considering the above drawbacks, it is desirable to provide smart green solar oven which utilize sun heat for maintaining constant temp in oven by circulating heat energy and which are more efficient in any weather conditions.
