in the beginning of this experiment, students must choose the solar panels that are already available in the lab and then check and see if there is a problem with the panel and the connectors. the checking process can be done easily by measuring the output voltage (or current).if you cannot get the reading from the meter please inform me immediately after that, please look at the back of the panel to obtain all the important information such as Im Vm Isc and Voc . if that particular information is not available, please ask the lecturer directly. then you need to measure the dimension of the selected solar panel and calculate the area. this number will then be used to deduce the sun's power in Watts that hits the solar panel.
