Solar energy is of huge interest due to the current situation with global warming. A number of solar technologies have been developed, such as photovoltaic, concentrated solar power, and solar water heating systems, to name a few. However, the technologies are being slowly implemented, and Botswana, with generous amounts of sun, is particularly suitable for solar energy. The opportunities were investigated due to the overwhelming and horrifying warnings echoed by many of the world's scientists regarding global warming. First, a handful of solar technologies were thoroughly investigated. A field study at Gakgatla village was then conducted, where the locals were interviewed. The interviews were analyzed, and solutions were suggested based on the identified needs of the locals. The biggest challenges identified were the lack of electricity in many of the households, parental figures not being supportive of the children's education, and theft. Additionally, many locals cooked with firewood. The most helpful solution but difficult to implement is photovoltaic panels. Solar water heating systems would also be helpful to the locals who predominantly had cold water. Additionally, solar cookers could help minimize exposure to hazardous smoke. Lastly, solar lamps could help students study during nighttime. Some locals also showed huge enthusiasm for what the future partnership with Botho University will bring. It is encouraged to develop a prototype of a solar cooker, particularly the parabolic solar cooker, in order to install solar cookers in Gakgatla village. Solar dryers would also greatly benefit the locals and are also suggested developments. Both of the mentioned solutions would help minimize the locals' exposure to the hazards of cooking with firewood. The solar dryers will also help eliminate bacteria by drying the food in a protected space inside a container.
