“…They have reported that the conical receiver is better than a cylindrical receiver to mitigate convective heat loss. Kamboj et al [20] experimentally investigated the solar steam boiler's thermal performance. An external steam boiler (receiver) was placed at the focus of the Scheffler solar concentrator.…”

In the present research article, an indirect type solar cooking system has been developed for indoor cooking. In the proposed cooking system, a cooking pot has been placed at a distance of 5 m from the parabolic dish collector, and the heat has been transmitted from the collector to the cooking pot by means of heat transfer fluid. A gear pump of 40 W and insulated pipes have been used to circulate the fluid. A number of experiments have been performed to analyze the performance of the cooking system. During the investigation, the system achieved the temperature of the heat transfer fluid up to 175°C. The time taken for cooking the rice and the black grams has been observed 21 and 68min, respectively. The average thermal efficiency of the proposed system for the entire day has been achieved at 13.11%.

“…Solar energy, even if having a high initial cost, should be preferred above other energy sources for its safety and environmental reasons. Solar energy has been studied extensively to maximize its benefits and because of its inconceivable capability of overcoming energy requirements, it has a wide scope of application in the pitch of water heating, 5,6 air heating, 7 air conditioning, 8 cooking, [9][10][11] water generation, 12 greenhouse, 13 and drying. 14 Flat Plate Collectors (FPCs) and Evacuated Tube Collectors (ETCs) are used for harvesting solar energy due to their simple design and effectiveness.…”

In the present work, an evacuated tube solar air heater (ETSAH) with inbuilt sensible heat storage material (SHSM) is experimentally evaluated. The system comprises two sets each having 50 evacuated tubes with an H‐type arrangement and a total collector area of 16.92 m2. For the purpose of hot air generation, ETSAH is simultaneously connected in series and in parallel with and without the use of reflectors. Three different mass flow rates of 122.90, 164.87, and 212.83 kg/h were fixed to get 12 diverse cases of ETSAH operation. The highest hot air temperature reported by the system is 121.7°C when it was connected in series with conventional reflectors at 212.83 kg/h of flow rate and 469 W/m2 average solar intensity. The system reported an overall average energy efficiency of 49.76% and an exergy efficiency of 17.97% with the highest average hot air temperature difference of 56.12°C from 09:00 to 20:00 h. Without the incorporation of any additional SHSM, the average hot air temperature delivered by ETSAH (when under the neighbor building shadow) is 49.73°C logged from 17:00 to 20:00 h. The economic analysis is also carried out to ensure its practical application and feasibility. For the best system performance, the annual cost of hot air generation is 0.0194 Rs./kg (0.0002433 $/kg).
