Solar cooking in Mozambique—an investigation of end-user's needs for the design of solar cookers

Sub-Saharan Africa is characterized by insufficient access to modern energy. One solution to this problem could be the use of solar energy to satisfy the current energy demand. However, solar energy technologies have shown limited success up to now. In the literature it is argued that solar cookers are often implemented as a "solution looking for a problem", without consideration of the end-user needs. This study contributes to this debate by investigating the energy patterns and cooking profiles of public institutions for the design and implementation of solar cookers in the case of Mozambique. Interviews were conducted with 12 health institutions in Maputo and Sofala province in Mozambique. The paper concludes that solar cooking presents one solution to overcome the energy crisis in Sub-Saharan Africa but not the only solution. Solar cookers could improve the current cooking situation if combined with heat storage, back up, or a hybrid system that ensures reliability also during evening hours and rainy days. In general we could see that solar cookers should fulfill a variety of requirements related to cooking habits, schedule of daily routine and performance that are considered to enhance levels of use. - Highlights: • The study investigates energy patterns of public health institutions in Mozambique. • The aim is to find out how a solar cooker should be designed for implementation. • Solar cookers should be reliable and lead to economic savings. • Users are skeptical towards the use of solar cookers during the rainy season. • Solar cookers need to be combined with other energy sources to be successful
