Two Types of solar cookers1 Box type  solar cooker 2 Parabolic solar cooker Box Cookers Solar box cookers (sometimes calledsolar ovens) are the most common and inexpensive type of solar cookers . Thesebox cookers have a very simple construction and they are made of low costmaterials. The outer box is often made of wood. The inner box is made ofinsulating material, which is covered with clear glass or with plastic, andoften has a reflector of aluminum .

According to Solar Cooker International,solar box cookers cook at moderate temperatures and often can accommodatemultiple pots. It can reach a temperature of 140? C. The solar box cooker, likeother solar cookers, needs direct sunshine to operate and produces zeroemission.  2 Parabolic solar cooker In comparison to solar box and panel cookers,parabolic cookers (sometimes called curved concentrator cookers) can reach muchhigher temperatures and can cook more quickly, but require frequent adjustmentand supervision for safe operation, according to Solar Cooker International. Itneeds more precision to focus the sunlight on the food in the pan. If thesunlight is not correctly focused on the food in the pan, the food will not becooked well. There are many designs for parabolic solar cooking appliances. Becauseof the parabolic shapes and with the aid of reflecting material quite a lot ofsolar energy is concentrated in the focal point.

A very high temperature ofbetween 200 and 300ºC can be reached because of a combination of the circulardesign, the size and the polished aluminium. It is suitable for baking,roasting and grilling. Parabolic solar cookers function well if they are usedcorrectly. However, they are not easy to make and need much care to use. Likeother solar cookers, parabolic cookers also need direct sunshine and theycannot store and keep sunlight for later use.
