This experiment was done to find out how different types of solar concentrators affect the performance of solar cells. The tests were carried out using a parabolic dish covered with a reflective aluminum sheet and a mirror
Procedure preview:
For this experiment, the independent variable is the type of solar reflector used. The dependent variable is the power output from the solar cell. This is determined by measuring the voltage and current produced. The constants (control variables) are the resistor, amount of sunlight, the temperature and the type of solar panel used. The parabolic dish is covered with the aluminum foil to give the surface a reflective finish. Be sure to use the more reflective surface of the foil. The aluminum foil is fastened to the parabolic dish using the masking tape. This experiment is conducted outdoors under .....
