Abstract: In this research, a novel indirect liquid jaggery-making system based on solar energy has been devised and assessed indoors in the climate of northern India. The thermic oil serving as the heat transfer fluid in the conical cavity receiver is heated using a parabolic dish concentrator. This accumulated intense heat is conveyed through connecting pipes to an indoor cooking pan. The system's performance was assessed over three consecutive days, processing 1 kg of sugarcane juice. Additionally, energy and exergy analyses were conducted, revealing a maximum energy efficiency of 11.08% and a maximum exergy efficiency of 2.31% for the system.

Keywords: parabolic dish concentrator; solar cooking; liquid jaggery; heat transfer fluid; HTF; energy efficiency; exergy efficiency.
