Solar cooker is a device for the preparation of food by concentrating solar radiation on the food to be cooked.
What is solar cooker state its principle of working.
Retention is the final principle in solar cooking if a solar cooker is not well insulated and if it does not have a cover or lid then all of the concentrated heat energy and all of the absorbed heat would quickly dissipate into the air and be lost to the surrounding environment.
Solar heating device like a solar cooker uses reflector to reflect sunlight to a small area where the cooking container is placed.
In solar cookers sunlight is used as a fuel.
The majority of solar cells are fabricated from silicon with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
A solar cooker consists of a mirror that helps in allowing the ultra violet rays of the sun and converts it into ir light rays.
Most solar cookers work on the basic principle.
A solar cooker must have the means to trap or hold the.
Sunlight warms pots and or food which is used for cooking.
The solar oven is a simple portable economical and efficient tool.
The solar cooker works mainly on three principles such as retention absorption and concentration.
We see the color white because virtually all of the light waves across the color spectrum are reflected away from the surface of the material.
Construction and working principle of solar power plant.
Solar oven also called solar cooker a device that harnesses sunlight as a source of heat for cooking foodstuffs.
In this section we will be discussing the working of solar cookers step by step.
It consists of a box made of non conducting materials like plastics fiber glass or wood.
How does a solar cooker work.
The walls of the box are made thick so as to minimise loss of heat due to radiation.
This was developed to lift water for irrigation purposes.
Figure shows a solar power plant with a low temperature solar engine using heated water from flat plate solar collector and butane as the working fluid.

However we see true black because all the light waves are being.
The light from the sun is actually focused at the container which gets heated thereby cooking the food.
Light waves are absorbed by dark colors.
Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.
It is painted all black from inside.
All colors together create white.
Especially in the developing world solar ovens are much to be preferred over other methods of cooking.

A solar cooker is a device that works with solar energy for heating and cooking food.
