The voltage generated by a photovoltaic (PV) cell is influenced by the amount of electrical resistance in the conductors running through the cell. The resistance of the conductors changes considerably as temperature changes. As a result, the temperature of PV cell a can have a significant impact on its power output.
In this experiment, you will compare the power output of a cold solar panel, one at room temperature, and one that has been heated. This will allow you to understand the effect of temperature on solar panel performance.
Use a Vernier Energy Sensor to measure power output while varying the temperature of a solar panel.
Determine the open circuit voltage (VOC) and short circuit current (ISC) for a solar panel at different temperatures.
Understand how temperature affects power output for a solar panel.
