Experimental investigation and performance analysis of box-type standard solar cooker with an inclined cover (BTSCIC)

This work proposes a novel transparent solar cooker design, and its performance is evaluated using a set of experiments. The cooker is fabricated from transparent and non-transparent, and lightweight material. The study was conducted at the Renewable energy laboratory in India (MNNIT Prayagraj). For thermal performance assessment of Box-type standard solar cooker with an inclined cover (BTSCIC) is compared with a box-type standard solar cooker (BSSC). The area, heat input, and thermal efficiency have all increased significantly. The total absorbing area increases by 32%, total solar radiation by 189%, absorber plate temperature by 19.8%, inner air temperature by 16.5%, pot water temperature by 17.1%, and inner wall average temperature by 58%, as compared to box-type Standard Solar Cooker. The average exergy was 4.2% (BTSCIC) and 2.61% (BSSC), respectively. The cost payback period of BTSCIC was 2.22 years and BSSC 1.5 years.
