This paper presents an experimental evaluation of portable modified conventional buckets of 10 l capacity. Out of ten modified portable storage, best three cases (viz. Non-insulated open plastic bucket (OPB), Non insulated plastic bucket top surface covered with a transparent cover (CPB), and Insulated plastic bucket closed with a transparent cover (ICPB)) are discussed. Maximum temperature rise after two hour time duration OPB, CPB, and ICPB are 29.82%, 47.36%, and 21.49% respectively as compared with the initial value the temperatures (22.8 ℃). At 14:45 hour CPB temperature reaches 35.6 °C which is 17.88 and 23.61% higher values as compared to the OPB and ICPB units. Net saving due to utilization solar energy in CPB for a range of 35-50°C is net saving increased by 12.34%, 25.76%, 40.73%, 57.93%, 76.45%, and 97.18% from 2017 to 2022 as compared with the saving in 2016.
