Ecology: Soes the anle of sun affect a solar cell
Case Study:
Does the Sun’s Angle Affect the Output
Of a Solar Cell?
Abstract
During the experiment to determine Solar Cell Energy, one unit of flexible solar cells was exposed to solar radiation at different angles in one axis of rotation. The cells were attached to a adjustable plane with a protractor that acted like a “see-saw” to adjust the angle of the solar cells to the Sun. Around the plane, a column of cardboard was constructed with black fabric covering the inside and bottom surfaces to prevent unwanted reflections. The time of day, temperature, voltage, and current was collected for everyone-degree change in angle. Using Microsoft Excel, the data of the voltage, and current was graphed with respect to angle.
Introduction:
The energy extracted from solar radiation by solar cells is vital to expanding our source of energy. Alternative sources of energy are being sought out constantly and solar energy has already been a primary source as solar cells have been in existence for many years. By figuring out how to maximize the efficiency of solar cells, engineers can build better cells and models for usage in homes and businesses. The purpose of this lab is to gain a better understanding of the relationship between solar cell voltage output and the angle of incidence with the Sun’s rays. Since the Sun is never stagnant, an understanding of this relationship will help in designing practical positioning of solar cells. Engineers and solar cell manufacturers have already pre-determined for this lab that solar cells are most efficient when placed exactly perpendicular to the Sun’s rays. The question for me is how much power can be produced at other angles in which certain arrangements and what relationships exist between the angle of incidence and power. The idea is that the solar cell will collect power very well for a certain range after its perpendicular position and then quickly fall as it is lowered to parallel and
