To successfully complete the whole project, initially we need to choose the proper solar panel with appropriate power rating and weight. Because, these things are directly related to the efficiency of the car. So, we did an experiment which involved the load management of the car while driving along with the V-I rating. Here, we chose a random car and put different bars with different weights on different position (. front hood, roof top/ seat, back hood) of that car. Then we connected the multi-meter to the respective input pins (‘+ve’ and ‘-ve‘) of the battery of that.
