Masyarakat di daerah kepulauan dan pesisir pantai sering mengalami kekurangan air, terutama musim kemarau. Pada daerah dimana masyarakat tinggal tersebut terdapat sumber energi dan air laut yang melimpah, terlebih pada musim kemarau. Pada kondisi ini sangat tepat menggunakan solar still untuk mengolah air laut menjadi air tawar menggunakan energi matahari. Penelitian ini bertujuan untuk membandingkan solar still double slope menggunakan pendingin nitrogen pada dinding (SSDS.WCN) dan tanpa pendingin SSDS. Penelitian dilakukan secara eksperimen, teoritis dan kajian eksergi. Solar still menggunakan pelat penyerap sirip berpori, kaca penutup double slope dan pendingin nitrogen pada dinding sebelah utara dan selatan yang di bandingkan dengan tanpa pendingin. Nitrogen pada sisi utara dan selatan menggunakan metode pembilasan (Flushing). Penelitian menghasilkan produktivitas air kondensat menggunakan pendingin nitrogen pada dinding (SSDS.WCN) secara eksperimen rata-rata sebesar 2.28 kg/10jam.m2 dan teoritis sebesar 2.15 kg/10jam.m2 lebih tinggi di bandingkan dengan tanpa pendingin (SSDS) secara eksperimen sebesar 1.98 kg/10jam.m2 dan teoritis sebesar 2.07 kg/10jam.m2. Efisiensi solar still menggunakan pendingin nitrogen pada dinding (SSDS.WCN) secara eksperimen rata-rata sebesar 37.05% dan teoritis sebesar 38.87% lebih tinggi di bandingkan dengan tanpa pendingin (SSDS) secara eksperimen sebesar 34.02% dan teoritis sebesar 35.27%. Efisiensi eksergi rata-rata menggunakan SSDS.WCN sebesar 4.78% dibandingkan dengan SSDS sebesar 4.49%. Solar still menggunakan pendingin nitrogen pada dinding dapat meningkatkan produktivitas air kondensat, efisiesnsi solar still dan efisiesnsi eksergi di bandingkan dengan tanpa pendingin.

The current research work involves the design and performance assessment of a solar still, which is a conventional single‐slope basin‐type solar still (CSSBTSS) and a modified single‐slope basin‐type solar still (MSSBTSS) under the meteorological conditions of Solan city, Himachal Pradesh, India (30.90° N, 77.09° E). The individual and the combined effect of different sample quantities of sensible Himalayan Rambaan fibers (HRFs) and mass of latent paraffin wax (PW) A48 on the performance of MSSBTSS is evaluated and compared with CSSBTSS. The use of HRF material enhanced the evaporation rate significantly and improved the daytime distillates. Besides, different masses of latent PW filled inside the aluminum tubes improved the nocturnal distillates. For the analysis, three cases have been considered which are, namely: Case 1, solar still with sensible HRFs (MSSBTSS‐HRF); Case 2, solar still with latent PW A48 (MSSBTSS‐PW); and Case 3, solar still with sensible and latent material (MSSBTSS‐HRF‐PW). The results showed that the maximum thermal efficiency for Cases 1 and 2 was improved by 30.02% and 42.41% with five sample quantities of HRF material and 5000 g of PW. For Case 3, the maximum energy efficiency was 90.71% with a gain of 45.16% over CSSBTSS. The economic analysis concluded that the cost per liter of distillate yield produced using MSSBTSS‐HRF‐PW and CSSBTSS is ₹1.5 and ₹1.6, respectively. These outcomes showed the great potential of MSSBTSS‐HRF‐PW approach towards enhancing the overall performance and cost‐effectiveness of solar still.

The existence of fins on a basin's flat absorber undoubtedly enhances the thermal efficiency and distillate output by increasing the exposed surface area of water to sunlight. However, the issue of shading caused by the fins hampers the productivity of distillers. Researchers are currently seeking a resolution to this problem. The current study conducted a performance comparison of hemispherical solar distillers using copper conical fins with a diameter of 4 cm and a height of 2 cm. The distillers were also equipped with copper conical fins‐filled red bricks, which were painted black. These fins were placed on the bottom of the basin at various spacing intervals (0, 1, and 2 cm) and a water depth of 2 cm. The experimental data showed that the productivity values of the hemispherical solar distiller using copper conical fins (HSD‐CCF) were 6.00, 5.40, and 5.00 L/m2, while the productivity values of the hemispherical solar distiller using copper conical fins‐filled with red bricks (HSD‐CCF & RB) were 7.00, 6.30, and 5.80 L/m2 at spacing distances of 0, 1, and 2 cm, respectively. The conventional hemispherical solar distiller without fins (CHSD) achieved a peak efficiency of 4.50 L/m2. The HSD‐CCF achieves cumulative yields of 33.33%, 20.00%, and 11.11% when utilizing copper conical fins at spacing distances of 0, 1, and 2 cm, respectively, compared to the THSD. The efficiency of the hemispherical sun distiller using copper conical fins‐filled with red bricks (HSD‐CCF & RB) is enhanced by 55.55%, 40.00%, and 28.89% when compared to the conventional hemispherical solar distiller (THSD), at spacing distances of 0, 1, and 2 cm, respectively. The study discovered that including copper conical fins packed with red bricks improves the efficiency of solar distillers. Furthermore, the study revealed that increasing the spacing between the fins further reduces shading, hence enhancing performance.
