In this experiment, you examine how the orientation of a photovoltaic (PV) panel relative to the sun affects its efficiency. Using sunshine (or a lamp) and a small PV panel connected to a digital multimeter, students vary the angle of the solar panel, record the resulting current output on a. . The purpose of this experiment is to analyze the system behavior when the light rays strike the PV panel and a portable rheostat is connected. The photovoltaic panel efficiency is calculated from the behavior of. . The efficiency of the panel is then calculated using voltage and current readings as well as compensating for solar orientation by using a known reference from a Solar PV radiometer. INTRODUCTION The primary purpose of this lab is to become more familiar with Solar Power. Measuring the power. . Then, you'll plot the data. Solar energy gene ration is beco ming one of the most widesp read soluti ons to address energy costs and g lobal climate change. With this project, you can get down to the atomic level and learn about the world of solid-state electronics as you investigate how solar cells work.
