what is solar cooker and solar panel and also give its limitation
Answers
Answer:A solar cooker is a device which uses the energy of direct sunlight to heat, cook or pasteurize drink and other food materials. Many solar cookers currently in use are relatively inexpensive, low-tech devices, although some are as powerful or as expensive as traditional stoves, and advanced, large-scale solar cookers can cook for hundreds of people. Because they use no fuel and cost nothing to operate, many nonprofit organizations are promoting their use worldwide in order to help reduce fuel costs (especially where monetary reciprocity is low) and air pollution, and to slow down the deforestation and desertification caused by gathering firewood for cooking.
Solar panels are devices that convert light into electricity. They are called "solar" panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Some scientists call them photovoltaics which means, basically, "light-electricity."
Explanation:
1.Cooking with solar cookers obviously requires sunlight, which makes it difficult to use during winter months and on rainy days. 2.Cooking also takes a significantly longer time compared to conventional methods. 3.Users must schedule their cooking time and maximize the use of sunlight.
Limitations: The amount of sun energy that could be collected. The radiation of sun is nearly fixed; the place that can be used to pave solar panels are limited; we cannot exploit all of sunlight to electricity because biosphere needs it; the energy conversion efficiency has a theoretical limit.
