“…Thermodynamic analysis of the designed dish was done using water as a working fluid considering average incident solar radiation (I) as 550 Wm −2 . Heat absorbed by the dish per unit area (q) was calculated using the relation below (Arjun Singh and Natarajan, 2021; Kopalakrishnaswami and Natarajan, 2021). …”

“…It was found that the stagnation temperature was augmented by about 7.4% and 11.3% at the bottom and top surfaces and also the average thermal efficiency was enhanced by about 6.3% compared to the conventional one. Arjun Singh and Natarajan (2021), Kopalakrishnaswami and Natarajan (2021) compared the various receiver designs with modified conical cavity receivers. Based on the numerical and experimental investigations, it was found that the modified conical cavity receiver was a better choice for the SPDC system compared to other receiver configurations.…”

Purpose The utilisation of renewable energy sources for generating electricity and potable water is one of the most sustainable approaches in the current scenario. Therefore, the current research aims to design and develop a novel co-generation system to address the electricity and potable water needs of rural areas. Design/methodology/approach The cogeneration system mainly consists of a solar parabolic dish concentrator (SPDC) system with a concentrated photo-voltaic module at the receiver for electricity generation. It is further integrated with a low-temperature thermal desalination (LTTD) system for generating potable water. Also, a novel corn cob filtration system is introduced for the pre-treatment to reduce the salt content in seawater before circulating it into the receiver of the SPDC system. The designed novel co-generation system has been numerically and experimentally tested to analyse the performance at Karaikal, U.T. of Puducherry, India. Findings Because of the pre-treatment with a corn cob, the scale formation in the pipes of the SPDC system is significantly reduced, which enhances the efficiency of the system. It is observed that the conductivity, pH and TDS of seawater are reduced significantly after the pre-treatment by the corncob filtration system. Also, the integrated system is capable of generating 6–8 litres of potable water per day. Originality/value The integration of the corncob filtration system reduced the scaling formation compared to the general circulation of water in the hoses. Also, the integrated SPDC and LTTD systems are comparatively economical to generate higher yields of clean water than solar stills.
