A solar water heater of the storage collector type was produced and tested at Julius Nyerere University in Kankan during the period from January 6 to 10, 2020. The device made it possible to heat 60 liters of water per day to nearly 73 °C on average. The solar collector has an area of 1,372m2. The device was placed in an environment of temperature varying between 22 °C and 31 °C. During the experiment, the day of 01/07/2020 was the least sunny, followed 01/06/2020 (very unclear sky). The daily average temperatures of the ambient environment, at the inlet and the outlet of the sensor are (26 °C; 25 °C and 70 °C) for 07/01202 and (27 °C; 26 °C and 73 °C) for on 01/06202, which corresponds to the daily returns 41% and 42% respectively. The days of 08 and 09/01/2020 the sunny days were favorable (clear sky), the average daily temperatures recorded are respectively: ambient (27 °C and 26 °C), re-entry (26.2 °C and 27 °C) and the output (73 °C and 75 °C) of the sensor, with yields (42% and 43%). The day of 01/10/2020 was the sunniest (very clear sky), the different average daily temperatures are as follows: 28 °C; 27 °C and 78 °C. Today's sensor efficiency is 46%. During these five days of experimentation, the average temperatures recorded are: ambient environment (26.8 ° C), at the input (26.24 °C) and the output (73.8 °C) of the sensor, with an average efficiency by 43%. This justifies the proper functioning of the system.
