Light waves are absorbed by dark colors.
What is solar cooker state its principle of working.
Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.
Especially in the developing world solar ovens are much to be preferred over other methods of cooking.
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.
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.
This was developed to lift water for irrigation purposes.
Construction and working principle of solar power plant.
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.
A flat plate collector.
Sunlight warms pots and or food which is used for cooking.
Solar oven also called solar cooker a device that harnesses sunlight as a source of heat for cooking foodstuffs.
A solar cooker is a device that works with solar energy for heating and cooking food.
In this section we will be discussing the working of solar cookers step by step.
All colors together create white.
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.
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.
The solar oven is a simple portable economical and efficient tool.
Solar cookers work on the basic principle that is the conversion of sunlight to heat energy which is used for cooking.
The light from the sun is actually focused at the container which gets heated thereby cooking the food.
A box type solar cooker is shown in fig.
A mirrored surface with high specular.
The walls of the box are made thick so as to minimise loss of heat due to radiation.
It is painted all black from inside.
The solar cooker works mainly on three principles such as retention absorption and concentration.
In solar cookers sunlight is used as a fuel.
However we see true black because all the light waves are being.
A solar cooker must have the means to trap or hold the.
Most solar cookers work on the basic principle.
Solar cooker is a device for the preparation of food by concentrating solar radiation on the food to be cooked.
