The productivity of a double slope solar still coupled with or without a parabolic trough collector is checked. A variety of steps are being taken to improve the efficiency of the solar still. Using wax as a phase change material (PCM) in a parabolic trough collector is a good way to store thermal energy. A parabolic trough collector (PTC) transferred incident energy to the solar still through a water tube connected to a heat exchanger filled in wax in the double slope solar still (PCM). Experiments were carried out after the orientation was set, with the water depth in the basin kept at 20 mm. The results show that solar stills with Parabolic Trough Solar Collector have higher temperatures and efficiency than solar stills without Parabolic Trough Solar Collector, as well as the ability to store latent heat energy in solar stills to ensure a constant supply of fresh water even after sunset. According to experimental results, the effect of the trough parabolic collector Parabolic Trough Solar Collector with PCM in the solar double slope enhances productivity by 40.7 and 38.93 percent, respectively.
