 *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.

-All other strategies have tended to fail for various reasons. In India, household solar cooking was not in line with cooking traditions. In South Africa, a loan system for solar systems could not be established due to lack of interest on the side of the banks and cookers were still too expensive for poorer families. In Burkina Faso parabolic cookers were disseminated using a loan system, but the project suffered from low payback rates.

 *The Solar Cooking Compendium is based on the experience gained in implementing the Solar Cooker Field Test (SCFT) in South Africa from 1996 to 2003. 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). Executing agencies were the Department of Minerals and Energy (DME) and the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ).

 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/>

-A solar cooker uses the energy of direct sunlight to heat, cook, bake or pasteurize food or drink. It only works when the sun shines, so solar cooking can never be a stand-alone technology. [[Solar Energy|Solar energy]] can be an ideal component of the energy mix of a household to complement other combustion-based stoves that can produce heat on demand based on other fuels. To which degree solar energy can replace other fuels depends on local dishes and cooking habits. It is also very much dependent on the local climatic conditions, which can vary tremendously over the course of a day or a year. All in all, over the year in a whole, fuel savings amount to roughly 30%-40%.<ref name="GTZ HERA (2007): Here Comes the Sun.

 Similar to the butterfly cooker is a model that has a circular bowl made from cement. In Tibet, it is easier to construct, cheaper, and can be afforded by poorer families. 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. Click [[:File:GTZ Manual for construction solar cooker cement-2006.pdf|here]] for a step by step introduction on how to build the cooker.
