At the beginning, I and my mentor did a research on some of the methods, through the website's academic, met several solar-faculty lecturers and talked with an electronic salesman. After a few studies have been done, then I and my mentor go to some of the electronics stores around Parit Raja, Batu Pahat to see and make the difference in the price of component items that must be available on the solar system. In some solar kid and also solar lamps in the store, we buy to do some research on circuit design and components that need to be used for solar panels.
