 *If the area around a house is covered with trees for shade, a solar cooker might have to be moved too far away from the house to be acceptable.
 *Solar cookers are ideal if cooking is not bound to happen at a certain time, e.g. for pasteurization of drinking water. In refugee camp situations or in locations, where other fuel options aren´t available solar cookers might be a good alternative.

It consisted of Phase 1 – Global market situation of solar stoves and social acceptance test (1996 - 1998) and Phase 2 – Estimate the market potential in South Africa, manufacture of solar stoves, and test marketing (1999 - 2003). The SCFT, a pilot program, was performed under a bilateral Technical Cooperation Agreement between the Governments of the Federal Republic of Germany and the Republic of South Africa (RSA).

 Panel-type solar cookers have a set of reflective panels focused on a black pot. These devices have been widely used in refugee camps as well as households. They can be very low in cost, with reflectors made of cardboard, plastic foam or other low-cost materials. Most panel solar cookers include a transparent cover or plastic bag in which a black cooking pot is enclosed. This increases the efficiency by reducing convective heat loss and exploiting the 'greenhouse effect'.<ref name="https://solarcooking.fandom.com/wiki/Category:Solar_panel_cooker_designs">https://solarcooking.fandom.com/wiki/Category:Solar_panel_cooker_designs</ref><br/>

This cooker has also been introduced in Afghanistan. The price of the cooker may vary considerably according to the cost of the surface mirrors and the cement. Disadvantages include a bowl that is more prone to breakage and the weight of the cooker (about 60 kg), making transport and handling difficult.

-Solar box cookers are much easier to construct than parabolic cookers and are frequently made from local materials by local artisans after they have been trained (Download: [http://www.bushcraftuk.com/downloads/pdf/solarbox.pdf Manual for solar box cookers]). Box cookers are less powerful than parabolic cookers and do not reach temperatures above 180 °C. Stir-frying is not possible, which makes them unsuitable for countries where this type of cooking is common. However, they are easy to handle, orientation to the sun is not as important as for parabolic cookers, and if the sun is temporarily covered by clouds, the temperature does not drop as fast as in parabolic cookers. During cloudy weather, a box cooker can serve as a retained heat cooker. Box cookers have been successfully disseminated in Bolivia.<ref name="GTZ HERA (2007): Here Comes the Sun.
