Question

Lab 9: Challenge Lab Physics 2702 Page 1 of I 9. Challenge Lab During this challenge lab you will have access to the same equipment you have used during this quarter i.e. DMMs, decade resistance boxes, solar panels, flood lamps, etc. Set up the following circuit (the resistor with the arrow trough it is the circuit diagram symbol for a variable resistor) .You will need to measure the "I vs. V" curve of a solar panel using the flood lamp held 20 cm above the solar panels as a "sunlight source You will then need to plot this data in Excel .You will then need to analyze the data to determine the peak power that the solar panel produces. As a reference, a typical I vs. V curve for a solar panel is shown below, with the "Peak Power a.k.a. maximum power point indicated. Your data for the solar panel should look similar Extra Credit: Assuming that sunlight from directly overhead provides 1000 W/m of radiant energy on a flat surface, and that typical Silicon solar panels like these are 15% efficient in converting sunlight into electrical energy, does the flood lamp do a good job mimicking the sun? Taken trom

Explanation / Answer

Setup needs to be done and data need to be taken to plot the graph.

Since silicon solar panels have low efficiency(~15%) so they do not mimick the sun poperly
