The potable water production using glass cover double slope solar still with a different heat absorption materials

Solar stills are straightforward method for acquiring refined water utilizing radiation from the sun. Some solar still models additionally upgrade the dissipation properties of the solar stills, for example, air velocity and water depth to produce larger amount of yield. The results showed that the performance of solar stills was improved through the increase in solar radiation. It was also determined that both internal and external reflectors are capable of increasing the amount of absorbed solar radiation on the basin liner. However, the distilled water produced by the solar still system is very limited. Therefore, this paper presents the experimental results of the performance of the solar still system. This experiment will be conducted in UniversitiTeknologi PETRONAS (UTP) solar field testing facility. The weather forecast and solar radiation intensity data will be obtained from Ipoh Meteo Department for the experiment. The parameters of the basin size, cover material and water depth are fixed. Generally, 3 types of experiments will be conducted:
 Black soil basin
 black painted basin
 Conventional solar still
When the water temperature increase the water production will increase, the water production from black painted basin solar still system is higher than both black soil and conventional solar still system. Water production from black painted basin solar still is 2.106 l/m², while black soil and conventional only produce 1.480l/ m² and 1.028l/m² respectively.
