1 Box type  solar cooker

2 Parabolic solar cooker

Box Cookers Solar box cookers (sometimes called
solar ovens) are the most common and inexpensive type of solar cookers . These
box cookers have a very simple construction and they are made of low cost
materials. The outer box is often made of wood. The inner box is made of
insulating material, which is covered with clear glass or with plastic, and
often has a reflector of aluminum . According to Solar Cooker International,
solar box cookers cook at moderate temperatures and often can accommodate
multiple pots. It can reach a temperature of 140? C. The solar box cooker, like
other solar cookers, needs direct sunshine to operate and produces zero
emission.

 

2 Parabolic solar cooker

In comparison to solar box and panel cookers,
parabolic cookers (sometimes called curved concentrator cookers) can reach much
higher temperatures and can cook more quickly, but require frequent adjustment
and supervision for safe operation, according to Solar Cooker International. It
needs more precision to focus the sunlight on the food in the pan. If the
sunlight is not correctly focused on the food in the pan, the food will not be
cooked well. There are many designs for parabolic solar cooking appliances. Because
of the parabolic shapes and with the aid of reflecting material quite a lot of
solar energy is concentrated in the focal point. A very high temperature of
between 200 and 300ºC can be reached because of a combination of the circular
design, the size and the polished aluminium. It is suitable for baking,
roasting and grilling. Parabolic solar cookers function well if they are used
correctly. However, they are not easy to make and need much care to use. Like
other solar cookers, parabolic cookers also need direct sunshine and they
cannot store and keep sunlight for later use.
