Experiment Shine Light On Solar Panel Measure

A solar panel is made up of many individual photovoltaic cells that convert light to energy.

Experiment shine light on solar panel measure.

Parabolic solar dishes on the other hand concentrate solar thermal energy to drive an engine which in turn drives a generator to create electricity. 3 record the solar cell current and observe the turn speed of the propeller of the electric motor. After completing the procedure allow each oven to cool before dismantling and take caution when handling the light. 2 connect the solar cell with the electric motor and a dmm to measure current.

Shine the light directly into box 2 and record the temperature rise every five minutes. Beyond using a good light source you need to align the solar cell toward it properly to get optimal power. Experiment with a dslr or hybrid camera to measure the overall brightness of the sky. Be sure you will get a reading when you use the bulb with the lowest lumens.

The goal of this experiment is to determine how changes in incoming light intensity affect the output of solar cells. Think of it as positioning a sail towards the wind. For best results dim overhead lights in the room before turning on the flashlight. But even better the reflectors greatly increase solar system output.

Put the camera in manual mode so that you can specify the shutter speed iso and aperture settings. Most photovoltaic panels absorb light in the relatively low energy red and green wavelengths. A solar panel installation company contacted hanna instruments about measuring light intensity. After 30 minutes carefully transfer the oven thermometer to box 2 and secure the cover.

Set up your lamp so that light will shine directly onto the solar panel. Your experiment will measure the effect of changing light intensity on power output from the solar cell. Turn on the flashlight and measure the surface area. Measure the surface area covered by the light rays at this angle.

Next rotate the flashlight to a 60 angle 60 solar elevation as shown on the right in figure 4 1. Record your measurements in the chart below. Set the ammeter output so that it will read milli amps ma. By showing how the reflectors scatter light the researchers started to take the risk out of using reflectors with solar panels.

Today photovoltaic cells can reach an efficiency of 40. The best way i have found to align a solar cell towards the sun it to mount a small stick perpendicular to the solar cell s surface then adjust the cell to minimize the stick s shadow. Connect the ammeter to the solar panel and set the solar panel on a flat surface. The wavelength of light absorbed by the panel determines how much energy is transferred.

1 place the solar cell on the table directly under the desk lamp and switch on the desk lamp.
