In industrial applications, hot water is used in food processing or as a heat transfer fluid. It is sometimes used to operate machines such as absorption refrigeration systems for the production of cold for the preservation of foodstuffs, etc. Producing hot water from energy sources that are not harmful to the environment, such as solar energy, is a challenge to limit the negative impacts of the use of fossil fuels on nature. Despite the advantages of solar hot water production and the potential of solar energy in Africa, this technique remains little used in Sub-Saharan Africa due to the lack of equipment and its high price. The objective of the project is to help design, manufacture and test a local, efficient and affordable solar water heater for the African market. The first experimental tests on the hot water production showed that the hot water storage temperature in the equipment\'s tank can reach 80°C, on sunny days under the test conditions in Benin. On non-sunny days, the completed collector should operate with an electric booster to reach the hot water storage temperature of 80°C required for some industrial applications (absorption machines). These first tests are conclusive and this low environmental impact device can be improved and popularised for industrial and domestic applications in sub-Saharan climatic conditions.
