Solar Panel Angle Calculation Name: Stephen Status: student Age: 15 Location: N/A Country: N/A Date: 2000-2001 Question: I'm doing an experiment which involves how the change of angle of a solar panel will affect the output it'll produce. The light source is an open 6 Watts light bulb, and a voltmeter will be connected to the solar panel to measure the output. Can you tell me what I can expect if the degree changes? And is there any formulas which I can use to measure the output whilst the change in degree? Replies: There is a formula for the relative intensity of radiation as a function of the angle of incidence A (measured from the panel), so directly overhead corresponds to an angle of incidence = 90 degrees. The relation is just sin(A). However, it is a bit more complicated beause the illuminated area of the panel increases as the angle of incidence decreases.
