Experiment Shine Light On Solar Panel Measure

Your experiment will measure the effect of changing light intensity on power output from the solar cell.

Experiment shine light on solar panel measure. Next rotate the flashlight to a 60 angle 60 solar elevation as shown on the right in figure 4 1. Think of it as positioning a sail towards the wind. 1 place the solar cell on the table directly under the desk lamp and switch on the desk lamp. 3 record the solar cell current and observe the turn speed of the propeller of the electric motor.

Beyond using a good light source you need to align the solar cell toward it properly to get optimal power. Measure the surface area covered by the light rays at this angle. Be sure you will get a reading when you use the bulb with the lowest lumens. For best results dim overhead lights in the room before turning on the flashlight.

After completing the procedure allow each oven to cool before dismantling and take caution when handling the light. Set the ammeter output so that it will read milli amps ma. Today photovoltaic cells can reach an efficiency of 40. Turn on the flashlight and measure the surface area.

Most photovoltaic panels absorb light in the relatively low energy red and green wavelengths. Parabolic solar dishes on the other hand concentrate solar thermal energy to drive an engine which in turn drives a generator to create electricity. A possible variation would be to investigate the effect of changing the color of the light. In the 1880s photovoltaic cells had an efficiency of 1 to 2.

Set up your lamp so that light will shine directly onto the solar panel. Shine the light directly into box 2 and record the temperature rise every five minutes. But even better the reflectors greatly increase solar system output. The goal of this experiment is to determine how changes in incoming light intensity affect the output of solar cells.

By showing how the reflectors scatter light the researchers started to take the risk out of using reflectors with solar panels. Connect the ammeter to the solar panel and set the solar panel on a flat surface. 2 connect the solar cell with the electric motor and a dmm to measure current. A solar panel installation company contacted hanna instruments about measuring light intensity.

The wavelength of light absorbed by the panel determines how much energy is transferred. Experiment with a dslr or hybrid camera to measure the overall brightness of the sky. Turn off the flashlight. A solar panel is made up of many individual photovoltaic cells that convert light to energy.

Put the camera in manual mode so that you can specify the shutter speed iso and aperture settings.
